Agilent Technologies 8922M/S Specifications
Reference
Specifications
The accuracy needs for testing GSM radios require the unit to be operated with the
High Stability Reference (Option 001) or an external high stability reference.
Fixed Reference Mode
Tunable Reference Mode
Allows offsetting the internal reference by a selected amount relative to the High
Stability Reference (Option 001) or an External Reference.
The Video Out connector on the rear panel outputs a 15 kHz PAL CVBS
underscanning compatible signal.
