Agilent has the power
measurement solution
you’ve been looking for
In a competitive environment such
as wireless manufacturing, testing
needs to be as efficient as the rest
of the manufacturing process. If you
are looking for a single-meter
solution that can do a full range of
power measurements with speed,
accuracy, and reliability, you’ll find
all these capabilities and more in
Agilent’s EPM-P series power
meters and E9320 power sensors.
Two EPM-P series models offer
excellent performance optimized for
wireless communications testing:
E4416A single-channel meter, 9 kHz
to 110 GHz, sensor dependent
E4417A dual-channel meter, 9 kHz
to 110 GHz, sensor dependent
Together with the E9320 power
sensors, the EPM-P power meters
measure the complex modulation
formats of today’s TDMA and CDMA
standards, as well as emerging wideband CDMA (W-CDMA) standards
for 3G wireless communications.
Power meter measurements include
peak, peak-to-average ratio, and
average power of RF and microwave
signals. Extensive triggering features
are available for making time-gated
measurements. Fast test times, with
measurement speed of up to 1,000
corrected readings per second,
help you increase throughput to
meet time-to-market and time-tovolume goals.
Designed for manufacturing
High-performance
power sensors
The EPM-P series power meters work
with the E9320 peak and average
power sensors to create a low-cost
solution that answers a wide range
of manufacturing test needs.
Six power sensors make up the
E9320 family:
E9321A, 50 MHz to 6 GHz,
300 kHz bandwidth
E9322A, 50 MHz to 6 GHz,
1.5 MHz bandwidth
E9323A, 50 MHz to 6 GHz,
5 MHz bandwidth
E9325A, 50 MHz to 18 GHz,
300 kHz bandwidth
E9326A, 50 MHz to 18 GHz,
1.5 MHz bandwidth
E9327A, 50 MHz to 18 GHz,
5 MHz bandwidth
Each sensor offers variable
bandwidth settings so that you
can maximize the sensor’s dynamic
range for your application.

The EPM-P series power meters
with the E9320 family sensors
provide peak power, average power,
peak-to-average ratio, and timegated measurements of the complex
modulation formats in wireless
communication systems.
Time-gated measurements are
performed using the meter’s
extensive triggering features, which
include continuous, level, external
TTL, and GPIB triggering. A
TRIGGER OUT port, on the rear
panel, allows other equipment
to be synchronized to the power
meter measurements, simplifying
measurement setups.
The flexible user interface allows
you to perform and display up to
four simultaneous time-gated or
free-running measurements. For
time-gated measurements, each
gate can be set up to measure the
average, peak, or peak-to-average
ratio, and you can set individual
start and duration times for each
measurement. This capability is
especially useful for measuring
power on TDMA signals that require
time-gating of various combinations
of peak and average power. On a
GSM signal, for example, you can
use time-gating to measure the
average power of the “useful”
time period (5% - 95% of the
burst duration), as well as to
measure the peak power, peak-toaverage ratio, and pulse droop.
One meter for TDMA, CDMA,
and W-CDMA power measurements
Gate 2 provides the burst average
power over the “useful” GSM time
period and Gate 1 indicates the peak
power over the complete timeslot.
A peak-to-average ratio measurement
can therefore be obtained by
combining Gate 1 - Gate 2 (in dB).
This peak-to-average measurement
is made on two different gate times
and should not be confused with the
peak-to-average ratio measurement
that can be carried out in a single
gate. A pulse droop measurement
can be obtained from the subtraction
of the two powers, Gate 4/Gate 3.
Speed without sacrificing
accuracy and repeatability
Faster test times help improve
manufacturing productivity and
efficiency. Designed for both bench
and ATE operation, the EPM-P
power meters and E9320 sensors
provide a measurement speed, over
the GPIB, of up to 1,000 corrected
readings per second. The power
meters’ 20 M-samples per second
continuous sampling rate gives you
the ability to accurately profile
complex modulation formats of up
to 5 MHz bandwidth, and modulation
bandwidth correction ensures
accurate peak measurements on
signals such as CDMA or W-CDMA.

Designed for R&D
In a design and verification
environment the EPM-P series
power meters now offer a complete
solution for power measurements.
Real time markers allow closer
analysis of the signal under test.
The gate control screen provides
graphical signal representation of
delta time, delta average, and delta
peak and delta peak-to-average
ratio with respect to markers 1 and 2
on the display. The trace control
feature provides a trace zoom
feature for closer examination of
a signal. Ideal for investigating
glitches and overshoot, and for
closer examination of the rise
time or fall time.
Measurement gates can be set by
numerical entry of the start and
length time. Also through the use
of the graphical gate set up to
define and control the start and
length of the gate.
Best in class calibration
reference
The 1 mW power reference provides
low measurement uncertainty for
power sensor calibration and
ensures a power output traceable
to the U.S. National Institute of
Standards and Technology (NIST)
and the National Physical
Laboratories (NPL), UK.
Thorough analysis and verification
of the power meter test processes
allow Agilent to provide best-in-class
0 dBm calibration reference
specifications. Temperature banding
of accuracy over one-year and
a warranted SWR specification
mean that you can test to tighter
specifications within your operating
environment with confidence in
your measurement results.
