8 Microwave Switch/Attenuator Driver
Example: Configuring a Single Drive Channel
The following example illustrates the sequence of command to configure a
single drive channel with continuous drive. In the example, the 34945A is
installed in slot 4 of the mainframe, and operations are directed to
channel 1 on remote module 3.
The drive source must be disabled before configuring pulse or paired
modes. The channel is then un- paired and the pulse mode disabled
(enables continuous drive). Power supply recovery time and settling time
is then set to 10 ms and 12 ms, respectively. Verify is then enabled.
The switches are set to a
CLOSe default state and OCOLlector drive with
an EXTernal power supply is selected. The channel is closed. The final
query of the channel state involves querying both verified state and
whether channel drive is occurring.

The ROUTe:CHANnel:DRIVE:STATe? query returns a 0 if the channel is not
being driven and a 1 if the channel is being driven.
