Description
Product Overview
The Keysight 34945A is a microwave switch/attenuator driver module specified for automated test system switching. It is part of the 34980A Multifunction Switch/Measure Modules. Verified model data includes channels/crosspoints: Each group of 34945A + 34945EXT drives up to 64 coils (32 SPDTs), topology: External microwave switch with step attenuator drive, position readback and LED indication, key performance: Up to 7 34945EXTs can be added to expand to 512 switching coils, rated capacity: 24 VDC driver; ratings depend on expansion boards, distribution boards, and external devices, and mainframe compatibility: Keysight 34980A. The same capabilities support multi-channel data acquisition and production test signal routing. Exact options, interfaces, accessories, calibration scope, and regional availability depend on the ordered configuration and should be confirmed before purchase.
