Keysight (formerly Agilent T&M) 83205A Cellular Adapter

Description

Description

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.
