About the Cellular Adapter
About the Cellular Adapter
This Cellular Adapter is a test set adapter for the HP 8920B RF Communications
Test Set. It works with the Test Set to test mobile transceivers built according to
the TIA/EIA-136 standard. The Test Set and the Cellular Adapter are collectively
referred to as the Test System.
TIA/EIA-136 is a standard which describes a Time Division Multiple Access
(TDMA) cellular communications system. The major feature which distinguishes
TIA/EIA-136 from its predecessor TIA/EIA-627 is the addition of a Digital
Control Channel (DCCH). To learn more about TIA/EIA-136, refer to the TIA/
EIA standard, or read Chapter 10, “TIA/EIA-136 Basics,” on page 265.
