Data sheet
All specifications apply over a 0 to 55 °C range (unless otherwise
stated) and apply after a 45 minute warm-up time. Supplemental
characteristics, denoted as typical, nominal, or measured, provide
additional (non-warranted) information at 25 °C, which may be
useful in the application of the product.
Definitions
Specifications: Represents warranted performance.
Typical: Represents characteristic performance which is non-warranted. Describes
performance that will be met by a minimum of 80% of all products. All typical values
are indicated by parenthesis.
Nominal: Represents characteristic performance which is non-warranted. Represents
the value of a parameter that is most likely to occur; the expected mean or average.
Measured: Represents characteristic performance which is non-warranted.
Represents the value of a parameter measured on an instrument during design stage.

Repeatability measures the ability of the instrument to return to a given power setting after a
random excursion to any other frequency and power setting. It is a relative measurement that
reflects the difference in dB between the maximum and minimum power readings for a given
setting over a specific time interval. It should not be confused with absolute power accuracy,
which is measured in dBm.1

Specifications for Analog Modulation
Composite modulation
Simultaneous modulation
16
AM, FM, and ØM each consist of two modulation paths which are summed internally
for composite modulation. The modulation sources may be any two of the following:
Internal, External 1, External 2.
Multiple modulation types may be simultaneously enabled. For example, AM, and FM
can run concurrently and all will affect the output RF. This is useful for simulating signal
impairments. There are some exceptions: FM and ØM cannot be combined. Two
modulation types cannot be generated simultaneously by the same modulation source.

Inputs and outputs
All front panel connectors can be moved
to rear with Option 1EM.
10 MHz input
Accepts a 1, 2, 5, or 10 MHz ±0.2 ppm. Nominal input
level –3.5 to +20 dBm, impedance 50 ohms.
[BNC, rear panel]
10 MHz output
Outputs the 10 MHz reference signal. Level nominally
+3.9 dBm ±2 dB. Nominal output impedance 50 ohms.
[BNC, rear panel]
External 1 input
This BNC input connector accepts a ±1 Vpeak signal for
AM, FM, pulse, and phase modulation. For all these
modulations, ±1 Vpeak produces the indicated deviation or
depth. When ac-coupled inputs are selected for AM, FM,
or phase modulation and the peak input voltage differs
from 1 Vpeak by more than 3%, the hi/lo annunciator light
on the display. The input impedance is 50 ohms and the
damage levels are 5 Vrms and 10 Vpeak.. If you configure your
signal generator with Option 1EM, this input is relocated
to a female BNC connector on the rear panel.
External 2 input
This BNC input connector accepts a ±1 Vpeak signal for
AM, FM, phase modulation, and pulse modulation. With
AM, FM, or phase modulation, ±1 Vpeak produces the
indicated deviation or depth. With pulse modulation,
+1 V is on and 0 V is off. When ac-coupled inputs are
selected for AM, FM, or phase modulation, and the peak
voltage differs from 1 Vpeak by more than 3%, the hi/lo
annunciator light on the display. The input impedance is
50 ohms and the damage levels are 5 Vrms and 10 Vpeak
If you configure your signal generator with Option 1EM,
this input is relocated to a female BNC connector on the
rear panel.
GPIB
Allows communication with compatible devices.
[rear panel]
LF output
Outputs the internally-generated LF source. Outputs 0 to
2.5 Vpeak into 50 ohms, or 0 to 5 Vpeak into high impedance.
[BNC, front panel]
RF output
Nominal output impedance 50 ohms.
[type-N female, front panel]
Sweep output
Generates output voltage, 0 to +10 V when signal
generator is sweeping. Output impedance < 1 ohm, can
drive 2000 ohms. [BNC, rear panel]
Trigger input
Accepts CMOS1 signal for triggering point-to-point in
manual sweep mode, or to trigger start of LF sweep.
The damage levels are –0.5 to +5.5 V. [BNC, rear panel]
Trigger output
Outputs a TTL signal: high at start of dwell, or when
waiting for point trigger in manual sweep mode; low
when dwell is over or point trigger is received, high or
low 2 µs pulse at start of LF sweep. [BNC, rear panel]
1. Rear panel inputs and outputs are 3.3 V CMOS, unless indicated otherwise. CMOS inputs will accept 5 V CMOS, 3 V CMOS, or TTL voltage levels.

General Characteristics
LAN connector
LAN communication is supported by the signal generator via the LAN connector. It is
functionally equivalent to the GPIB connector. The LAN connector enables the signal
generator to be remotely programmed by a LAN-connected computer. The distance
between a computer and the signal generator is limited to 100 meters [10BaseT].
For more information about the LAN, refer to the Getting Started chapter in the
Programming Guide.
