Agilent Technologies 34970A Switch User Manual


 
Scanning With External Instruments
If your application doesn’t require the built-in measurement capabilities
of the 34970A, you can order it without the internal
DMM. In this
configuration, you can use the 34970A for signal routing or control
applications. If you install a multiplexer plug-in module, you can use the
34970A for scanning with an external instrument. You can connect an
external instrument (such as a
DMM) to the multiplexer COM terminal.
To control scanning with an external instrument, two control lines are
provided. When the 34970A and the external instrument are properly
configured, you can synchronize a scan sequence between the two.
