 Tip: click on the picture to zoom in

Description

The 8920A is a full-feature, one-box test set designed to meet service and repair needs in the cellular and land mobile communications market. Combining the functionality of more than 20 instruments, the 8920A offers the capabilities needed in testing cellular phones, land mobile radios, and communications systems up to 1 GHz.
 

  • Intuitive call processing interface for cellular phone test
  • Functions of more than 20 complete instruments
  • Frequency ranges:
    • Signal Generator: 30 MHz to 1 GHz
    • RF Analyzer: 10 MHz to 1 GHz
  • Portable and lightweight
  • Optional full-span spectrum analyzer, tracking generator and adjacent channel power meter
  • Built-in IBASIC computer
Test and Troubleshoot Faster

The HP 8920A decreases test and troubleshooting time by simplifying standard measurement tasks and providing extensive capability in one box.   Transmitters and receivers are simply characterized with single-key RX, TX, and duplex tests.  Measured results are displayed on a single screen as either digital measurements or analog bar graphs.  All settings and measurements are easily accessed and changed using the front-panel knob, and all settings can be saved in nonvolatile save/recall registers or on a SRAM card media for future access.

Spectrum Analyzer with Tracking Generator and Adjacent Channel Power

The HP 8920A's optional synthesized spectrum analyzer measures signals from 400 kHz to 1 GHz with variable spans from 5 kHz to 1 GHz (full span).   Display resolution is selectable from 1, 2, or 10 dB per division.  The tunable marker provides automatic readout of frequency and amplitude, or of relative frequency or amplitude from a reference.  The tracking generator included with the spectrum analyzer allows for swept characterization of devices with fully settable amplitude and sweep spans (to 1 GHz).  The newly added adjacent channel power measurement capability includes both variable bandwidths and variable frequency offsets.   Typical performance is -70 dBc.

Signaling Encoder and Decoder

The optional signaling encoder and decoder support all common signaling formats, including tone sequential, digital paging, DTMF, trunking, and cellular signaling.  Common standards are list-selectable and easily modified for different user formats.  The decoder displays the tone or digital sequence transmitted, and the duration of the tone or tone pair.  For digital paging transmitters, the decoder will display the address/code, the message, and the transmission rate.
