Example: Configuring a Single Drive Channel

The following example illustrates the sequence of commands to configure a single drive channel with continuous drive. In the example, the 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.

ROUTe:CHANnel:DRIVE:STATe? (@1301)

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.
