3. INSTALLATION & OPERATION:
3-1. MOUNTING: Each Digital Attenuator is supplied with 12 mounting holes (4-40 UNC-2B x 4.1 [0.16 Deep])
located on the front, back, top and bottom end of the attenuator. Refer to the appropriate API Weinschel
Specification/ICD drawing for mounting hole location.
Figure 1. Connector Location
CAUTION
When applying an RF signal to the RF INPUT connector, DO NOT exceed the maximum allowable
power level specifications of the unit.
Do not over torque the SMA connectors more than 7 inch pounds. Damage may occur.
3-2. RF CONNECTORS & CABLE INSTALLATION: The Model 4205 series contains two SMA female connectors
labeled J1 and J2 that mate nondestructively with SMA male connectors per MIL-STD-39012. Care should be taken
to prevent strain on the interconnecting cables, since damage here may not always be apparent. Check the attaching
RF cables and the SMA connectors for signs of cracked insulation and/or bent or worn pins prior to connection. Tests
show that connectors must be clean for accuracy and stability. This requires an inspection and cleaning of each
connector immediately before use. When cleaning precautions are observed regularly, connectors can maintain
their stability for over several thousand connection cycles. API Weinschel recommends a torque value of 7 to 10
inch pounds when connecting any RF cable to the attenuator's RF connectors.
3-3 CONTROL CONNECTORS: Model 4205 attenuators can be controlled in one of two modes: parallel TTL or
USB. The TTL control connector is a standard 10-pin ribbon cable connector that mates with an AMP 746285-1 style
connector. The USB connector is a standard 5-pin USB mini B series. NOTE: Only one interface should be connected
at a time. DO NOT supply a connection to both control ports simultaneously.
3-3.1. Parallel TTL Connector (J4): In parallel TTL mode up to eight TTL control signals (model dependent) are
used to activate or deactivate a particular attenuation cell. A TTL high will enable the attenuation state for the cell,
whereas a TTL low will maintain the cell in its zero attenuation state. In addition, there are two DC supply voltage pins
which are used to supply power to the unit.

3-3.2. USB Connector (J3): In USB mode the attenuator is controlled and powered via a standard USB 2.0
connection to a USB host. The 4205 operates as a USB CDC device, so it may be controlled via any software that
can communicate to a standard COM port. Programming is done via simple ASCII strings to control the device (see
the Command section paragraph 3-4).
For ease of use, the 4205 has two modes of operation: console and raw mode. Console mode provides a simple
command-line based interface that can be used in conjunction with any standard terminal emulator program. Console
mode sends command prompts ('>'), echoes received characters, issues error messages, and supports the
backspace key for simple editing, while raw mode is more suitable for programming. By default, the unit is shipped
with Console mode enabled, but this operation can be change by the user (see the CONSOLE command for more
details).
3-4. USB DRIVER INSTALLATION: When you connect the 4205 to the USB for the first time, you should be
presented with the New Hardware Wizard.
Follow the steps shown below to install the USB CDC .inf file. (NOTE: A copy of the INF information is included in
paragraph 3-6 of this document. If you do not have an electronic copy, you can create one using Notepad. Copy and
paste the information into Notepad and save it as a plain text file with the name AW4205_CDC.INF)

To verify that the driver has installed properly, view the Ports section in Device Manager. You should see the 4205
listed as a USB COM port. Note the assigned COM port number.
Using a terminal emulator, open a connection to the COM port shown above. The default COM port settings should be
acceptable, as these are unused by the 4205. If the 4205 is in Console mode (the default), you should see the signon
message.
API Weinschel
11
Model 4205
IM-612
The COM port numbers are assigned by Windows based on the device USB VID, PID, and Serial Number. The 4205
uses different USB PID codes for each of the three models as shown below:
Model
USB PID
4205-31.5
106F
4205-63.5
106E
4205-95.5
106D
By default, the attenuators are all shipped with the USB serial number set to '000000'. If you are using a single
attenuator of a given model, you can ignore this setting. If you wish to use multiple attenuators of the same type, you
can change the serial number to a unique setting so that each attenuator is assigned a different COM port. This can
be done through the Console using the IDN command, which allows the user to change the serial number/ID to any 6character setting. As the units are serialized at the factory on the product label, you may wish to use this number for
easy identification.
To assign a new serial number to the attenuator, connect the unit as normal. It is recommended to do this with only a
single attenuator connected to the USB to avoid any confusion. Note the serial number located on the product label
(ie 100), and send the command 'IDN serialno', replacing serialno with the actual desired string. Unplug and reattach
the attenuator's USB connection. You will have to reinstall the driver (this time you can let Windows install it
automatically), after which it should be re-enumerated with a different COM port number.
3-5. COMMAND OPERATION: Commands are comprised of text-based ASCII strings. The command parser is
case-insensitive, so either upper or lower case characters are acceptable. Command parameters may be separated
with either an ASCII SPACE char (0x20) or an ASCII COMMA char (0x2E), but the separator character used must be
the same within an individual command string. Additional SPACE characters are ignored. Input program messages
may be terminated using either an ASCII CR character (0x0D) or an ASCII LF character (0x0A). Command message
strings are limited to 64 characters total, including the terminator. Multiple commands can be included in one
message by separating the individual commands with an ASCII SEMICOLON character ';' (0x3B), up to the 64
character message limit. Typically, Response messages sent from the device are terminated using both a CR (0x0D)
and LF (0x0A) to terminate the message. The output terminator sequence may be changed using the RMT command.
A list of supported commands can be seen by typing 'HELP' at the Console prompt.
The command structure/operation is similar to that used in IEEE 488.2, and includes some of the 488.2 Common
Commands such as *IDN?, *RST, *CLS, and *OPC?, in addition to device specific commands. In 488.2, programming
commands take one of two forms: a Program message or a Query message. Program messages are used to send
commands to the device, while Query messages are used to elicit a response. Query commands are those that
contain a '?' character. In general, the device does not generate any response to a program message unless the
message contains a valid Query command. (Note that this does not apply when operating in Console mode, or when
using some commands such as HELP which are designed to provide the user general information). You can use this
feature to provide a method to synchronize command execution with the controller by appending a Query to the
desired command, and waiting for the response. For example, sending "*CLS;*OPC?" will place a "1" in the output
queue when the *CLS command has been executed. Query commands that return multiple values will have the
values separated by an ASCII COMMA character (0x2E). If multiple Query commands are included in the same
message, the individual query responses will be separated with an ASCII SEMICOLON character (0x3B).
An Error Queue is provided that logs the results of command/execution errors in a FIFO fashion. The queue entries
can be read using the ERR? command, which returns both an error code and a descriptive text message, such as
101, "invalid command"
When the queue is empty, ERR? returns the message 0, "no error". The queue can be emptied by repeatedly
API Weinschel
12
Model 4205
IM-612
sending ERR? until all entries are read from the queue, or via sending the *CLS message.
Unless otherwise specified, commands revert to their default setting at system reset/poweron, with the exception of
the system setup and configuration commands which store their setting in non-volatile memory (NVM).
3-5.1. Command Reference: In the command descriptions that follow, argument types are described using the
following additional conventions to indicate the relative size of the parameter:

character data, including the max number of characters allowable. (ie string8 has a max of 8 chars)
Numeric arguments default to decimal (base 10) notation, but may optionally be provided in hex if appropriate by
using a "0x" prefix (ie 0x0a = 10)
Required command keywords are shown in CAPITAL letters, and arguments are shown in italics. Square brackets '[]'
may be used to indicate an optional parameter, for example [select]. Optional parameters, if not supplied by the user,
assume the default setting specified in the text.
3-5.2 Application Specific Commands: Attenuation value settings are specified in dB, with up to 1 digit of
precision after the decimal point for attenuators that support step sizes of < 1dB. When specifying integral dB values,
usage of the decimal point format is strictly option (ie '10' is the same as '10.0'). The attenuation setting must be a
multiple of the attenuators intrinsic step size or the command will generate an error. For example, an attenuator that
has a stepsize of 0.5 dB will accept settings of 0.5, but will generate an error if set to 0.3. For responses, attenuation
values will be formatted to the base precision of the attenuator.
Attenuation switching speed requirements are built into the command execution time and are always
enforced such that if you execute a command sequence such as "ATTN 10;*OPC?" the response will not be sent until
the attenuator has been programmed and has changed state. The attenuator can be switched at the maximum rate
that commands are executed, which is typically in the 1-2ms range.

interval
Remarks:
This command ramps the attenuation value at a user specified rate. The start_db and end_db values
can be any settings valid for the attenuator, and the attenuation will ramp up or down as required. The attenuation
value will step according to the current STEPSIZE setting. Attenuation values are changed at the rate specified by
interval, which is in units of msec. Note that no other commands can be executed until the fade operation is
completed. The query form of the command (FADE?) will return the current attenuation values as the steps are
executed.
Return Value: none
Example(s):
STEPSIZE 1.0
// set stepsize to 1 dB
FADE 10.0 85.0 500
// fade from 10dB to 85dB in STEPSIZE increments at a rate of 500ms
STEPSIZE 0
// set stepsize to default (0.5dB)
FADE? 90 0 1000
// fade from 90dB to 0dB in 0.5dB steps at a rate of 1000ms (1sec)
90.0
// values are sent as the attenuation changes

Remarks:
This function sets the output Response Message Terminator (RMT) sequences. The val parameter
specifies the character sequence used, and can specify up to two characters, typically as a hex word high byte-low
byte pair. Common definitions for the terminators include the ASCII CR (0x0D) and LF (0x0A) characters. A single
character may be specified either by using 0 for the high byte, such as 0x000D, or by only specifying a single
character (ie 0x0D). On output the characters are sent low byte then high byte, unless it is specified as 0. Note that
the CONSOLE mode will always use a fixed CRLF (0x0A0D) sequence. This value is stored in non-volatile memory
(NVM), and does not take effect until the next system restart event.
Return Value: none

APPENDIX A
APPENDIX A
CARE AND HANDLING OF MICROWAVE COAXIAL
CABLE ASSEMBLIES
A-1 CARE AND HANDLING OF ASSEMBLIES.
A-3 MAKING INITIAL CONNECTIONS.
To ensure accurate measurements and optimal
performance of Weinschel products, the microwave coaxial
cable assemblies used in system and test setups must be
properly used and maintained. Proper connections, routine
inspection of all cables, and cleaning of the connectors are
extremely important procedures which can prolong the
longevity and accuracy of equipment.
Exercise caution when mating cables. Poor connections
lead to poor system performance. They can also damage not
only the cable assembly, but more significantly, front or rear
panel connectors on the equipment itself which may be more
difficult to repair.
A-2 CABLE INSPECTION.
Routinely check external cables for signs of cracked
insulation, dents, twists, flattening, signs of jacket abrasion, or
other signs of abuse. Wrinkles in the jacket indicate that the
minimum bend radius has been exceeded. Most often, this
occurs near the marker tubes and connectors.
Also inspect the connector interfaces for the following:
•
•
•
•
•
•
•
Bent pins (male).
A-3.2 MATING CONNECTORS. Gent ly mate the
connectors by hand, taking care not to force the coupling nut
at the slightest resistance. It is often possible to feel whether
or not the pins are mated. If the coupling nut is difficult to
turn, either the pins are not mated, the coupling nut is
cross-threaded, or one of the connectors has been damaged by
excess torque.
Bent or missing tines (female).
Worn or chipped plating.
Damaged or displaced dielectric inserts.
Thread damage.
Folded or mushroomed outer interface rims.
Mushroomed pin shoulders (male) or tine ends
(female).
• Score lines on pins and outer interface rims
visible to the unaided eye.
• Recessed or protruding pins.
It is advisable to clean the connectors prior to inspection to
make subtle damage more apparent. If any of the above is
noted, replace the assembly before its further use results in
equipment damage. Also inspect the mating connectors for
similar damage.
Inspect the connector interface for signs of debris. Debris
may be in the form of:
•
•
•
•
A-3.1 ALIGNING CONNECTORS. Align the center
lines of two connectors before actual mating. Male retaining
nuts contain a small amount of necessary play which may make
it possible to mate the threads without the pins being properly
aligned. Pin misalignment can damage pins and dielectric
inserts.
Plating chips or other metal particles.
Dust or dirt.
Oily films.
Other miscellaneous foreign particles.
Never hold a male connector coupling nut
stationary while screwing a female connector into it. This
rotation can erode the plating and damage both the outer
interface rim as well as the pin. If the pins become locked,
serious damage can result to both the equipment and the cable
assembly.
A-4 ENSURING PROPER CONNECTOR TORQUE.
A-4.1 OVERTORQUING. Once connectors have been
properly mated, apply only the proper amount of torque.
Overtorquing damages both connectors involved. Also, a
connector which has been damaged by overtorquing, in turn,
damages every connector to which it is subsequently mated.
It usually leads to poor system performance as well.
Overtorque can cause:
•
•
•
•
•
•
•
•
Bent pins.
Recessed or protruding pins.
Recessed or protruding dielectrics.
Chipped plating.
Damaged coupling threads.
Coupling nut retaining ring damage.
Mushroomed outer interface shells.
Mushroomed pin shoulders.
If signs of debris are present, clean the connector interface
as directed in Paragraph A-6.
A-i
CARE & HANDLING OF COAXIAL CABLES
A-4.2 HEX-NUT TYPES. To mate a connector of the
hex-nut type, always use a torque wrench set to the correct
torque value. Tighten the connector slowly until the wrench
snaps. Tightening too quickly can cause the wrench to exceed
its set limit. Do not snap the wrench more than once as this
also causes overtorque.
A-4.3 KNURLED NUTS. T ighten connectors with
knurled nuts by hand. If this does not provide sufficient
tightness use a hex-nut connector and torque wrench instead.
Never use pliers to tighten a connector. Table A-1
recommends torque specifications for the various types of
connectors.

A-5 PROPER CABLE HANDLING.
Never exceed the minimum bend radius specified for a
cable. Guard against tight bends at the end of connector strain
relief tubing, or at the ends of marker tubing where they may
be less noticeable. Although cable bend may seem slight, the
actual radius of the bend at the point of angular departure may
be far smaller than the acceptable radius.
Never pinch, crush or drop objects on cable assemblies.
Also, do not drag a cable over sharp edges as this will pinch it
and cause it to exceed the minimum bend radius.
Never use a cable assembly to pull a piece of equipment.
Cables and connectors are not designed to support or move
equipment.
A-ii
A-5.1 SECURING CABLES. Use toothed, rubber-lined
"P-clamps" to hold cables in place. If it is necessary to use
tie-wraps, use the widest possible wrap and the lowest setting
on the gun to ensure the minimum pressure on the cable.
A-5.2 STORING CABLES.W he n st oring cables,
minimize cable "set" by coiling them in large diameters (1 or
2 feet). Unroll the cable properly when it is ready to be used;
do not pull the loops out hastily. Similarly, re-roll them when
storing them away again.
A-6 CLEANING CONNECTOR INTERFACES.
Use the following guidelines in cleaning connector
interfaces:
a. Do not use chlorinated solvents including common tap
water. These solvents are extremely penetrating and
sometimes ruin otherwise good devices and assemblies.
b. Moisten a cotton swab with isopropyl alcohol. Roll
the swab on a paper towel to remove excess.
c. Use the moistened cotton swab to wipe away debris.
Do not try to dissolve the debris by overwetting the swab.
d. Repeat the cleaning process using additional swabs as
necessary. If metallic particles are embedded in the
dielectric, use an eyeglass and a sharp pick in an attempt
to dislodge them. Swab again.
e. When satisfied that the interfaces are clean, blow them
dry with dry compressed air, or preferably dry nitrogen
(pressurized spray cans work well). Do not use breath.
f. Clean the mating connectors. These may be the source
of the debris.
