Relay pointer operations
The DDC commands in the following table use relay setups as the Model 707B or 708B instrument
would use patterns.
The
U2,n
DDC command returns the channels that are closed in a format based on the DDC
Gn
command. The corresponding command for this operation returns the channels contained in the
pattern as a csv list. There is no need to send a pattern to the relays. Operations that are to be done
to the channels of a pattern are done on the pattern correctly. For more information, see
(on page 5-4).

The Model 707B or 708B can expand to other Keithley Instrument’s products that have a TSP-Link
connector available. When the command listed in the following table is executed, it provides the
number of nodes present in the TSP-linked system.
A feature of the Model 707B or 708B is that these remote nodes are not limited to Model 707B or
708B instruments. They can be remotely linked to any Keithley product that supports TSP-Link. For
