Configure the 8920B to meet your
radio test needs by selecting options
tailoring it for your radio and test
application. For a more turnkey, automatic test solution, select one of the
Agilent Technologies 11807E software
packages designed to run on the
8920B’s internal controller.
AM, FM, ΦM, and SSB Radios
The optional signaling encoder and
decoder support common land
mobile radio formats including
tone sequential, digital paging,
and DTMF signaling. Common standards are included, and are easily
modified for different user formats.
For thorough and fast testing to
international standards, 11807E
software packages are available
for AM, FM, and ΦM radios.
Test high-power transmitters with
Option H08 for frequency and
power measurements up to 100 W
continuous (125 W intermittently
with 10 seconds per minute duty
cycle). With this option, AM and
FM measurements can be made
on inputs from -16 to +50 dBm.
Trunked Radios
The signaling option also provides
protocol for testing both LTR and
EDACS radios. Use the manual
mode to perform quick functional
checks and to verify system programming. For full characterization, run a suite of tests on multiple channels with 11807E LTR or
EDACS software test packages.
Cordless Phones, Data Terminals,
Short-Range Transceivers
Test cordless phones, data terminals, and short-range transceivers
by adding Option 007, which
shifts the input range for RF
power measurements to a level
ideal for characterization of lowpower transmitters. RF power
with fully specified accuracy can
be measured on signals as low as
40 µW. Option 007 reduces the
maximum continuous input
power of the 8920B to 2.4 W.
Call Processing
Cellular phone testing with the
8920B has a whole new look and
feel with the new call processing
subsystem. New front panel
screens simplify manual testing
as well as GPIB programmability.
In call processing mode, the 8920B
emulates a cellular base station,
allowing you to automatically
establish and maintain a cellular
link between the test set and cellular phone. Use the front-panel
knob to register the phone, originate a call, page the phone, hand
off to other channels, change
power, and release calls; as well
as make fast parametric measurements while the phone is on a
voice or traffic channel. Messages
received from the mobile, such as
phone number, ESN, SCM, protocol version, model, and order
acknowledgment are displayed on
an interactive screen where you
can monitor the phone’s status.
The new call processing features
are available for AMPS, DAMPS,
NAMPS, TACS, NTACS, JTACS,
and DCCH radio test.
Cellular phone test capabilities
enhance the 8920B’s fast and accurate
parametric measurements.
