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.

DUT

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 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 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.

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 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 true-average, 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 19901.

The simplified block diagram shown
here illustrates this technique.

Low Sense

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.

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.

Measurement speed

Normal: 20 readings/s
x2: 40 readings/s
Fast: 110 readings/s
Buffered (50 readings):

1000 readings/s

The U2000 Series USB sensors have
two measurement modes:

Average only mode (default mode):
optimized for wide dynamic range. In
this measurement mode, a trigger can
be controlled externally via TTL input.

Normal2 mode: used for making aver­age power measurement in a defined
time interval (time-gated measure­ment) with reduced dynamic range.
A trigger can be derived from an RF
signal (internal trigger) or controlled
externally via TTL input (external
trigger).

1. The 1000 reading/s is the derived measurement speed from the first 50 readings in buffered mode. The maximum number of measurements that can be obtained in one
second is 250 readings in buffered mode.

2. Not applicable for U2004A.

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 AUTO (default) range Low power path High power path Switching point

U2000/1/2/4A –60 to +20 dBm –60 to –7 dBm –7 to +20 dBm –7 dBm
U2000/1/2H –50 to +30 dBm –50 to +3 dBm +3 to +30 dBm +3 dBm
U2000/1B –30 to +44 dBm –30 to +23 dBm +23 to +44 dBm +23 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.

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

Offset at switching point:

≤ ± 0.5% (≤ ± 0.02 dB) typical

high power path is selected. The high
power path remains selected until

approximately –7.5 dBm is reached
Switching point hysteresis:
± 0.5 dBm typical

as the signal level decreases. Below

this power, the low power path is

selected.

measurement noise. For overall accuracy, refer to the measurement uncertainty calculator which is available on the Agilent 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:

Otherwise, use Equation 2:

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.

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 ρ)
relates to the SWR based on the fol­lowing formula:

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.

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.

SWR =
