Scanning with external instruments
If your application doesn’t require the built-in measurement capabilities of the
34970A/34972A, you can order it without the internal DMM. In this configuration,
you can use the 34970A/34972A for signal routing or control applications. If you
install a multiplexer plug-in module, you can use the 34970A/34972A for
scanning with an external instrument. You can connect an external instrument
(such as a DMM) to the multiplexer COM terminal.
