Stand-Alone Instruments
When the test equipment is not accurate and repeatable, the number of devices that must be reworked or retested grows, consuming precious time and space. The 8920B greatly reduces the uncertainty in a “Pass” or “Fail” result, with accurate and very repeatable test measure­ments. As a result, test margins can be minimized without passing bad devices or failing good ones.
When using the 8920B you can be sure of passing more good radios in production tests and of consis­tently finding those that are out of specification.

Test Speed that Lowers
Your Cost Per Test
The 8920B takes you another step forward in manufacturing produc­tivity. Processing speed improve­ments reduce the automated test time of cellular radios by approxi­mately 15% when compared to rack and stack systems and more than double the computing speed over the 8920A for initial trans­ceiver measurements and GPIB commands.
This means lower cost per test and more throughput from your production line.
Flexibility to Meet More of
Your Testing Needs
The 8920B meets your test needs on multiple radio test lines; test­ing land mobile, trunked, cord­less, and cellular phones while also meeting your need for fast parametric tests, troubleshooting, QA, and call processing test.
Hardware and firmware upgrades keep your 8920B’s capabilities current, giving you flexibility to meet new radio testing needs.
8920B flexibility allows you to standardize on a single platform, reducing training and support needs.

400 kHz to
1 GHz
The optional spectrum analyzer measures signals from 10 MHz to 1 GHz with variable spans from 5 kHz to 1 GHz (full span). Display resolution is selectable between 1, 2, and 10 dB per division. The tunable marker provides automatic readout of frequency and amplitude, or relative frequency and amplitude from a reference. Other marker functions, usually available only in stand-alone spec­trum analyzers, include peak hold, marker-to-peak, marker-to-next peak, marker-to-center-frequency, and marker-to-reference; all of which speed up and simplify signal searching and measurement.

Flexible spectrum analyzer and oscilloscope capabilities
The tracking generator, included with the spectrum analyzer option, allows for quick and accurate characterization of filters, duplexers, combiners, and RF to IF conversions. Broadband RF devices can be characterized with single sweeps up to 1 GHz. The tracking generator also includes fully settable amplitude and frequency offset, and a tunable marker that provides automatic readout of frequency and amplitude of any response point.
Included in the Option 102 is the capability to make adjacent chan­nel power (ACP) tests on transmitters. This test measures undesir­able signals that spill into and interfere with neighboring channels. ACP tests can be made by varying three parameters: channel off­set, channel bandwidth, and resolution (measurement bandwidth). The dynamic range for ACP is typically -65 dBc to -70 dBc, adequate for most radio standards.
The standard built-in 50 kHz digital oscilloscope provides multiple triggering formats (internal, external, and encoder); single-shot and pre-trigger view for signaling analysis; and full marker capability with automatic level and time readout. Time/division, volts/division, and vertical offset are displayed and easily changed using the front­panel knob. The trigger delay feature allows you to choose the delay from 20 µsec to 3.2 seconds.
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.

Measurements of TX frequency error, TX power, FM deviation, and AF frequency are made on a mobile sta­tion’s RF carrier while on a voice channel. Additional audio measurements, such as RF sensitivity, and FM hum and noise, can be made from call processing screens using audio break-outs to connect audio to the test set’s audio in and audio out connectors.
Forward and reverse data message informa­tion at the bit level is displayed in an easy­to-read format to sim­plify message analysis for troubleshooting.
Easier Programming
The new call processing subsys­tem also creates a more user­friendly programming interface for automated cellular phone test. High-level GPIB commands such as “page” and “register” simplify code generation for phone test.
Additional Capabilities
• A-key generation via GPIB
• Random data entry via front panel and GPIB

Cellular Phone Test
Digital Cellular Phone Test
High-quality digital cellular measurements have never been easier—a real bonus for users immersed in the rapidly chang­ing technologies of digital cellu­lar radios. From programming a test sequence to troubleshoot­ing phones, the new call pro­cessing subsystem simplifies even the most complex DCCH (TIA/EIA-136) measurements.
TDMA Cellular Adapter
The 83206A TDMA cellular adapter (8920B Option 800) provides a complete π/4 DQPSK signal gener­ator, π/4 DQPSK modulation ana­lyzer, data source, and BER ana­lyzer for TDMA measurements on DAMPS (IS-54B) and DCCH (TIA/ EIA-136) phones. The 83206A replaces the 83201B TDMA cellu­lar adapter (previously 8920B Option 500) for making measure­ments on TDMA dual-mode DAMPS phones, adding digital control channel test features to fully char­acterize DCCH phones. Refer to the 8920B configuration guide, literature number 5968-5919E for configuration requirements.
Faster Software
The new Agilent Technologies 11807E Option 014 AMPS/NAMPS/ DAMPS/DCCH phone test package automates DCCH tests such as call processing from a DCCH, RF power versus channel, receiver sensitivity versus channel, and battery life.
Option 014 takes advantage of new 8920B Option 800 call pro­cessing features—enhancing test speed by as much as 25% and adding a more robust control channel link making your phone less likely to tune to an off-the-air control channel during test. Refer to the 8920B configuration guide for a complete list of tests.
True-Average Power Measurements
For the most accurate power measurements on TDMA signals, include the new 10 W to 50 µW power measurement range option (8920B Option 006). This option increases power measurement accuracy by extending the 8920B’s ±5% power measurement perform­ance down to 50 µW and enabling true-average power measurements with the 83206A TDMA cellular adapter. True-average power meas­urements are performed directly with a new average power detector.

Additional DCCH Test Features Available Include:
Mobile Reported Parameters for MAHO—Given a list of up to six
neighbor channels, the test set directs the mobile to report back the RSSI detected for each neigh­bor cell. The test set displays the mobile reported RSSI for neigh­bor channels and RSSI and BER of the current channel.
Power Control—Once on a digital traffic channel, the user can com­mand the mobile to adjust power.
Unique Programming of FACCH and SACCH—Allows the user, via
software, to send custom FACCH and SACCH messages to the mobile.
BER Calculation—Transmits a PRBS sequence and calculates loopback BER.
DCCH Test Features—Such as DCCH authentication, SMS, Caller ID, and Message Waiting, can be easily added with front-panel firmware updates to the 83206A as they become available.
Quick-test, Base Station Emulation Mode—Provides a
base station emulation mode that bypasses call processing procedures to quickly get to a traffic channel. This feature is important for man­ufacturing test where avoiding overhead time associated with call processing can greatly reduce parametric test times.
Agilent Technologies 83236B PCS Interface
Extend DCCH test capabilities for future PCS phone test by adding the 83236B PCS interface to trans­late DCCH measurement capabil­ity to the PCS band. Power meas­urement accuracy and speed are maintained at PCS band frequen­cies with an internal power meter for measurements on CW and TDMA (π/4 pulsed or continuous) signals.

Program the 8920B from an
external controller or use the
built-in controller for a self-
contained automated test
solution.
External Controller
Use any controller or PC that sup­ports the IEEE 488.2 interface to write test programs for the 8920B. Examples include an IBM compat­ible PC with the Agilent Technolo­gies 82335B GPIB interface card, Agilent Series 200/300, or Series 700 workstation with the E2070B GPIB interface card.
Agilent VEE Supports the 8920B!
Agilent Visual Engineering Envi­ronment (Agilent VEE) is a graph­ical programming language opti­mized for instrument control. Use VEE with new 8920B drivers to reduce test development time com­pared to conventional programming techniques. For more information on VEE refer to “VEE the Produc­tivity Language” brochure, litera­ture number 5980-0841E.
Built-In Automation Capability
Built-In Controller
The 8920B has a built-in Instrument BASIC (IBASIC) controller that pro­vides powerful automation capa­bility. The controller operates using the IBASIC programming language. IBASIC is a subset of HP BASIC, Rocky Mountain Basic (RMB) used in the Agilent Series 200/300 controllers, and BASIC for Windows.
Control External Instruments
The built-in controller can be used to control all instrument functions making the 8920B a self-contained automated test station.
The 8920B can also control exter­nal instruments. The IBASIC pro­gramming language has the capa­bility to output commands over GPIB or serial bus to other instru­ments and query them for meas­ured results. This gives you the capability to add a power supply or a second signal generator to your test system and use the 8920B as the system controller. This eliminates the additional space and expense of a separate system controller.
11
Radio Interface Card–Option 020
The 8920B has an optional built-in radio interface card for automat­ing module and radio testing. This eliminates the need for a system operator to key the transmitter or manually control operation of the module or radio.
The radio interface card has six­teen parallel data lines, two inter­rupts, and brings the audio in/out lines and a relay closure out from the MIC/ACC connector located on the front panel. All are con­trolled by either the 8920B IBA­SIC control language, an external GPIB controller or manually. All data lines provide TTL level out­puts and require TTL level inputs.
Develop Custom IBASIC Programs
IBASIC programs can be devel­oped in several different ways:
1) Programs can be created using IBASIC mnemonics on a controller or a PC and then downloaded into the 8920B over the optional GPIB bus, or run from the con­troller or PC.
2) An ASCII terminal can be con­nected to the RS-232 bus and pro­grams developed on the 8920B using the ASCII terminal keyboard as the input device.
3) Programs can be created on a PC using IBASIC mnemonics and saved as an ASCII file. This ASCII file can then be loaded into the 8920B via the RS-232 bus or PCMCIA card.
The Agilent 83224A IBASIC devel­opment tool kit is available to aid you in writing your own IBASIC programs. Once written, programs can be stored on memory cards. These PCMCIA memory cards are available in 64 KB (83230A) and 1 MB SRAM (83231A) sizes for storing all of your programs.
Agilent Technologies 11807E soft­ware provides a solution for auto­matically testing your radios with­out having to invest in software development time. The software is written in IBASIC for the 8920B internal controller. It fully con­trols the 8920B, testing radios against recognized international standards. This automation gives you the capability to produce
higher quality radios at a lower cost per test by requiring less user training, testing radios con­sistently, and increasing your throughput at a given test station. For more information see the 11807A/E radio test software product overview, literature num­ber 5968-1379E.
