Multiplexer Modules for 34980A

The 34980A Multiplexer switches can be used to connect one of many different points to a single point. You can connect to an external instrument or switch multiple analog signals to the 34980A internal DMM. Multiple multiplexers can be connected together via the 4 analog buses to create an even larger multiplexer. The break-before-make feature also ensures that no two signals are connected to each other during a scan. All multiplexer modules also include a relay switch counter to help predict when relays need to be replaced.
