Retrieve card settling time
Although base channel settle time cannot be returned, additional delay time that was specified with
the
channel.setdelay(channelList,delay)
command can be returned using:
channel.getdelay("allslots")
Delays for each channel in csv format are returned. For more information, see
(on page 5-4).

TSP equivalent command
Description
U6

Trigger source control
The DDC commands in the following table control the trigger source for advancing the relay setups.
The Model 707B or 708B instrument provides similar functionality, but omits triggering on talk and
triggering on X. For more information, see
(on page 3-1).

The DDC
U0
command provides information on several areas of the Model 707A or 708A instrument
in one long csv form. There is no one command to provide the same functionality as the
U0
command, but the series of Model 707B or 708B commands shown in the following table can be used
to provide very similar information, without the need to parse a long, unwieldy string.
