Introduction
The 7712 switching module offers a 50 Ω dual 1 × 4 multiplexer configuration with 10 rear-panel SMA
connectors. Multiple multiplexers can be cascaded to build scalable matrix and multiplexer systems for a large
number of devices under test and RF source/measurement instruments. One channel in each multiplex bank is
always closed to the corresponding OUT connector. The 3.5 GHz RF switching capability of the 7712 makes it
ideal for testing wireless modules operating in the 2.4 GHz and lower industrial, scientific, and medical (ISM)
radio bands.
Item shipped may vary from model pictured here.
The 7712 includes the following features:
3.5 GHz bandwidth
Dual 1 × 4 multiplexer configuration
Onboard switch closure counter
If you are using this switching module with the 2700, 2701, or 2750, please see Model 7711 and
7712 User's Guide, Keithley Instruments document number PA-818.
