SAMPle
The SAMPle subsystem provides commands to set and query the interval between
channel measurements (pacing).
Subsystem Syntax SAMPle
:TIMer <interval>
:TIMer?
SAMPle:TIMer
SAMPle:TIMer <interval> sets the time interval between channel measurements.
It is used to provide additional channel settling time. See “Settling Characteristics”
discussion on page 101.

Comments · The minimum <interval> is 10 µs. The resolution for <interval> is 2.5 µs.
·
If the Sample Timer interval multiplied by the number of channels in the specified
Scan List is longer than the Trigger Timer interval, at run time a “Trigger too
fast” error will be generated.
·
The SAMP:TIMER interval can change the effect of the
SENS:CHAN:SETTLING command. ALG:CHAN:SETT specifies the number of
times a channel measurement should be repeated. The total settling time per
channel then is (SAMP:TIMER <interval>)X(<chan_repeats> from
SENS:CHAN:SETT)
·
When Accepted: Not while INITiated

*RST Condition: Sample Timer for all Channel Lists set to 1.0E-5 seconds.
Usage SAMPLE:TIMER 50E-6 Pace measurements at 50 µs intervals
SAMPle:TIMer?
SAMPle:TIMer? returns the sample timer interval.
