Compact “power meters”,
simple set-up
The U2000 Series are standalone
sensors. That means they essentially
operate like power meters, just in
smaller forms. No reference calibrator is required. The fact that each
sensor draws minimal power from a
USB port—and that it doesn’t need
additional triggering modules or
power adaptors to operate—makes
it more portable, especially for base
station testing. Setting up is easy:
just plug it to the USB port of your
PC or laptop—or even select network
or handheld spectrum analyzer—and
start your power measurements.
The figure below illustrates the very
simple, straightforward setup of the
U2000 Series.

High accuracy
Each U2000 Series sensor provides
excellent linearity, SWR and uncertainty specifications, so you can be
confident in every measurement you
make.
Wide range, high power
The U2000 Series’ dynamic range
spans across a wide 80 dB, taking on
high power up to +44 dBm.
Remote monitoring and tests
With the U2000 Series sensor
plugged to a networked USB hub,
you can conveniently monitor power
measurements of an antenna tower
from the control room, beyond the
limits of USB cable lengths.

Introducing the U2000 Series USB Power Sensors (continued)
Faster production testing of
multiple channels
Transform your signal generators and spectrum analyzers
into accurate power meters
The U2000 Series’ fast measurement
speed helps reduce test time. This,
coupled with the capability to enable
monitoring of more than 20 channels
simultaneously, is an advantage in
the production line where efficiency
is of utmost priority.
You could literally have a power meter next to you—or instead, turn your Keysight MXG signal generator or N9340A/B handheld spectrum analyzer into a
power meter for accurate power measurements. Even with the U2000 connected, you can switch between power measurements and the device’s original
function at any time. You can also use the U2000 with your Keysight PNA
network analyzer for source power calibration.
The U2000 Series has both internal
and external zeroing capabilities.
With internal zeroing, high isolation
switches in the sensor are opened to
isolate the sensor from the deviceunder-test (DUT) it is connected to.
As such, you don’t need to power-off
the DUT or disconnect the sensors.
This speeds up testing and reduces
sensor wear-and-tear.
No manual input of calibration data
is required. All calibration factors,
as well as temperature and linearity
corrections, are stored in the sensors’
EEPROM, auto-downloaded at
calibration.
Often times, you’d need to automate
your tests. The U2000 Series sensors
are well-equipped for seamless integration to your system with industrystandard SCPI compatibility. They
also come with built-in triggering
capability to allow receipt of external
triggers from other instruments.
Intuitive power analysis software
The N1918A Power Analysis Manager software not only displays measurements
with the U2000 Series, it also provides various features and functions to help
you monitor and troubleshoot signals efficiently and effectively.
The U2000 Series is also supported by the Keysight BenchVue software (version
3.0 and above). BenchVue makes it easy to control your power meter to log
data and visualize measurements in a wide array of display options without any
programming.
This software is available on the Keysight Instrument Control DVD, which is
included with each sensor. You can download the latest version of the software
cost free at www.keysight.com/find/BenchVue. Upgrading to the paid BenchVue Power Meter Pro version (BV0007A) provides unrestricted data logging.
Keysight recommends that you use the BenchVue software for new projects or
applications.

Diode-based sensors frequently
rely on the application of correction factors to extend their dynamic
range beyond their square-law
region, typically in the range of –70
to –20 dBm. While this technique
achieves measurement of CW signals
over a wide dynamic range, it fails to
do so for modulated signals when the
signal level is above the square-law
region. Modulated signals must be
padded down, with their average and
peak power levels within the diode
square-law region, for accurate average power measurement.
The simplified block diagram shown
here illustrates this technique.
The U2000 Series USB power sensors
are true-average, wide-dynamicrange RF/microwave power sensors,
based on a dual-sensor diode pair/
attenuator/diode pair topology as
proposed by Szente et. al. in 19901.
This technique ensures diodes in the
selected signal path are kept in their
square law region—with output current and voltage proportional to input
power. The diode pair/attenuator/
Low Sense+
RF in
Low Sense–
High Sense+
High Sense–
diode pair assembly can then yield
the average of complex modulation
formats across a wide dynamic range,
irrespective of signal bandwidth.
The dual-range Modified Barrier
Integrated Diode (MBID)2 package
incorporates diode stacks in place of
single diodes. This further improves
measurement accuracy of high-level
signals with high crest factors without incurring damage3 to the sensor.
Implementation of both techniques
in the U2000 Series USB sensors
enable effective average power measurements of a wide range of signals,
including multitone and spread spectrum signals used in CDMA, W-CDMA
and digital television sytems.

Switching point
The U2000 Series power sensors have two measurement paths: a low power path and a high power path, as shown in the
table below.
Models

High power path

U2000/1B
–30 to +44 dBm
–30 to +23 dBm
+23 to +44 dBm

Each power sensor automatically
selects the proper power level path.
To avoid unnecessary switching when
the power level is close to the switching point, switching point hysteresis
has been added.
Offset at switching point:
≤ ± 0.5% (≤ ± 0.02 dB) typical
Switching point hysteresis:
± 0.5 dBm typical
Example with U2000 “A” suffix
sensors: Switching point for the
U2000/1/2/4A sensors is at –7 dBm.
Hysteresis causes the low power
path to remain selected until approximately –6.5 dBm as the power level
is increased. Above this power, the
high power path is selected. The high
power path remains selected until
approximately –7.5 dBm is reached
as the signal level decreases. Below
this power, the low power path is
selected.

This accuracy is essentially a combination of linearity, instrumentation accuracy, and traceability to absolute accuracy at 50 MHz, 0 dBm.
Note: Mismatch uncertainty, calibration factor uncertainty, and power level dependent terms (zero set, drift, and noise) are excluded in this
specification and specified elsewhere in the data sheet.
2. The accuracy for –7 to +1 dBm (U2000/1/2A), +3 to +11 dBm (U2000/1/2H), and +23 to +31 dBm (U2000/1B) power level will be dominated
by zero set and measurement noise. For overall accuracy, refer to the measurement uncertainty calculator which is available on the Keysight
Technologies Web site.
3. It is advisable to perform external zeroing on the U2000 Series power sensor for power measurement level below –30 dBm. During the external zeroing process, the RF input signal must be switched off or the device-under-test disconnected from the U2000 Series power sensor.

Effect of time-gating and averaging
on normal mode measurement noise:
The normal mode measurement
noise wil depend on the gate length
(time-gated period in second) and the
number of averages. The noise can
be approximately calculated with the
following equations.
If the gate length is < 2.73 µs, use Equation 1:
Noise = Noise per sample ×

Number of averages
Otherwise, use Equation 2:
Noise = Noise per sample ×

4
×
Number of averages Gate length/(0.68 µs)
Note: If the noise value obtained
from Equation 1 or 2 is lower than
the measurement noise specification,
use the value as specified in the
measurement noise table.
Effects of averaging on noise:
Averaging over 1 to 1024 readings
is available for reducing noise. The
table below provides the measurement noise for a particular sensor
with the number of averages
set at 16 (for normal mode) and
32 (for x2 mode). Use the noise
multiplier, for the appropriate of
averages, to determine the total
measurement noise value.
Example:
U2000A power sensor, –60 to
–35 dBm, normal mode, number
of averages = 4

Calibration factor and
reflection coefficient
Frequency
Calibration factor (CF) and reflection
coefficient (Rho) data is unique to
each sensor. The CF corrects for the
frequency response of the sensor.
The reflection coefficient (Rho or ρ)
relates to the SWR based on the
following formula:
10 to 30 MHz
30 MHz to 2 GHz
2 to 14 GHz
14 to 16 GHz
16 to 18 GHz
SWR =
1+ρ
1–ρ
Maximum uncertainties of the CF
data are listed in the following table.
There is only one set of CF data used
for both high and low power paths of
each sensor.
