Product specifications of Keysight Agilent 83205A (From Used-Line T&M Specifications)

  • Launch Date
  • Status Discontinued by Manufacturer

The HP 83205A Cellular Adapter is an accessory to the HP 8921A Cell Site Test Set. The Cellular Adapter and Test Set are connected together via front-panel and rear-panel cables and work together to form a Test System. The Cellular Adapter adds digital signal generation and analysis to the analog test capabilities of the Test Set.

The 83205A Cellular Adapter can be configured as one of three different options.

  • 83205A CDMA Cellular Adapter, Option 001
  • 83205A CDPD Cellular Adapter, Option 002
  • 83205A CDMA/CDPD Cellular Adapter, Option 003

The 83205A CDMA Cellular Adapter (Option 001) and the 83205A CDMA/CDPD Cellular Adapter (Option 003) include DSP (Digital Signal Processing) hardware and firmware to test the transmitter and receiver portions of Code Division Multiple Access (CDMA) base stations. Systems using the CDMA format use encoders and decoders to digitize speech and add call processing information. The  83205A CDPD Cellular Adapter (Option 002) and the 83205A CDMA/CDPD Cellular Adapter (Option 003) include Cellular Digital Packet Data (CDPD) digital signal generation and analysis. The CDPD assembly found in Cellular Adapter Options 002 and 003 provides the hardware and firmware to perform CDPD protocol processing.
