Agilent Technologies 8920A Datasheet
The Agilent Technologies 8920A RF communication
test set is a full-featured, one-box test set designed
to meet the service and repair needs of today’s RF
wireless communications market.
Single keystroke transmitter and receiver testing
simplifies radio test. Signaling for multiple formats
is supported, including tone sequential, digital paging (CCITT, POCSAG, ZVEI, etc.), DTMF, trunking,
and cellular signaling.
For cellular phone test, the call processing interface emulates a base station, allowing you to automatically establish and maintain a cellular link
between the test set and an analog cellular phone.
The built-in controller allows you to automate
measurements and test routines, and control external instruments. Combined with the Agilent 11807A
software, it provides a self-contained, automated
radio test solution.
Key Features:
• 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
