Adding Settling Delay for
Specific Channels
This method adds settling time only to individual problem measurements as
opposed to the SAMPle:TIMer command that introduces extra time for all
analog input channels. If problems are seen on only a few channels, the
SENS:CHAN:SETTLING <num_samples>,(@<ch_list>) command can be
used to add extra settling time for just these problem channels. What
SENS:CHAN:SETTLING does is it instructs the VT1422A to replace single
instances of a channel in the Scan List with multiple repeat instances of that
channel if it is specified in (@<ch_list>). The number of repeats is set by
<num_samples>.
Example:
Normal Scan List:
100, 101, 102, 103, 104
Scan List after SENS:CHAN:SETT 3,(@100,103)
100, 100, 100, 101, 102, 103, 103, 103, 104
When the algorithms are run, channels 0 and 3 will be sampled three times,
and the final value from each will be sent to the Channel Input Buffer. This
provides extra settling time while channels 1, 2, and 4 are measured in a
single sample period and their values also sent to the Channel Input Buffer.
