TRIGger
:TIMer <seconds>|MIN|MAX
:TIMer? [MIN|MAX]
This command sets the channel-to-channel interval in the trigger layer
(the ARM:TIMer command sets the sweep-to-sweep interval in the
trigger layer). This timer is valid only if the TIMer is set using the
TRIGger:SOURce command.
You can set seconds to any value between 0.000 (MIN) and 99999.999
(MAX) in increments of 0.001 seconds. When power is applied, the value is
set to 0 (MIN).
The TRIGger:TIMer? query returns the channel-to-channel interval in
seconds. The returned number is a value between 0 and 99999.999
(seconds). The optional parameters MIN and MAX allow you to query the
module for these values instead of looking them up in the command
reference. MIN returns “0” and MAX returns “99999”.
[ROUTe:]
[CHANnel:]DELay <seconds>,<channel_list>|ALL
[CHANnel:]DELay? <channel_list>
This command specifies a delay time (from 0 to 99999.999 seconds, with
1 ms resolution) between when a channel in the scan list is closed and
the next operation begins (and, if configured, a trigger out pulse is sent).
The delay time can be set individually for each channel in the scan list,
or one delay can be set for all channels in the scan list. Note that, even if
the trigger source is set to IMMediate, the scan list will not advance until
the delay time is met. Following power on or a reset (*RST) command,
the delay time is set to “0”.
The channel_list can be:
•
a single channel, use DEL (@snn);
•
multiple channels, use DEL (@snn,snn...);
•
sequential channels, use DEL (@snn:snn);
•
groups of sequential channels, use DEL (@snn:snn,snn:snn);
•
or any combination of the above.
The ROUTe:CHANnel:DELay? query returns the delay time of each
channel included in the channel_list. A comma-delineated set of values is
returned. The values are in same order as in the channel_list and in the
form of (snn,snn,mm,...), where snn is the channel number and mm is a
stored channel setup.
