Introducing the U2000 Series USB power sensors

The U2000 Series enable simpler, lower-cost

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

The U2000 Series fast measurement speed
of 1000 readings/s in buffered mode 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.

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
device-under-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
industry-standard SCPI compatibility. They also
come with built-in triggering capability to allow
receipt of external triggers from other
instruments.

Transform your signal generators and spectrum analyzers into accurate
power meters

You could literally have a power meter next to youor instead, turn your Agilent 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 Agilent PNA
network analyzer for source power calibration.

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.

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 dBm 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 U2000 Series USB power sensors are true­average, wide-dynamic-range RF/microwave
power sensors, based on a dual-sensor diode
pair/attenuator/diode pair topology as
proposed by Szente et. al. in 1990

. The
simplified block diagram shown here illustrates
this technique.

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/diode pair assembly can then
yield the average of complex modulation
formats across a wide dynamic range,
irrespective of signal bandwidth.

Diode (MBID)

package incorporates diode
stacks in place of single diodes. This further
improves measurement accuracy of high-level
signals with high crest factors without

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.

Calibration factor and reflection
coefficient

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 )
relates to the SWR based on the following
formula:

SWR =

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.

The uncertainty analysis for the calibration
data was done in accordance with the ISO
Guide. The uncertainty data reported on the
calibration certificate is the expanded
uncertainty with a 95% confidence level and
a coverage factor of 2.

Using the U2000 Series with the N1918A Power Analysis Manager

The N1918A software is available in two versions: the basic Power Panel and advanced Power
Analyzer. Power Analyzer provides full access to the softwares complete features and capabilities
and its license, N1918A-Option 100, is available for purchase separately. A free, fully functional
trial version of the Power Analyzer is accessible for 30 days upon installation from the bundled
N1918A Power Analysis Manager CD. The table here shows functions accessible with each
version when used with the U2000 Series.

Display units:

Absolute: Watts or dBm
Relative: Percent or dB

Display resolution:

Resolution of 1.0, 0.1, 0.01 and 0.001 dB in log
mode; one to four digits in linear mode.

Default resolution:

0.01 dB in log mode; three digits in linear mode
Zero: For performing internal and external
zeroing.

Range: Sensor-dependent, configurable in
1-kHz steps.

Relative: Displays all successive
measurements relative to the last referenced
value.

Offset: Allows power measurements to be
offset by 100 dB to +100 dB, configurable in

0.001 dB increments, to compensate for
external loss or gain.

Duty cycle: Duty cycle values between 0.001%
to 99.999% can be entered in increments of

0.01% to display a pulse power representation
of measured power. The following equation is
used to calculate the displayed pulse power
value: Pulse Power = Measured Power/
Duty Cycle

Limits: High and low limits can be set in the
range between 150.00 dBm to +230.000 dBm,
in 0.001 dBm increments.

Preset default values: Channel Offset (dB) =
0, Duty Cycle Off, Frequency 50 MHz, AUTO
Average, AUTO Range, Free Run Mode,
dBm mode.
