SAMPle
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”
on page 157
Parameters
Comments • The minimum <interval> is 40 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. SENS:CHAN:SETT specifies the
number of times a channel measurement should be repeated for channels defined
in an algorithm. The total settling time per channel then is (SAMP:TIMER
<interval>) X (<chan_repeats> from SENS:CHAN:SETT)
• When Accepted: Not while INITiated
• Related Commands: SENSE:CHAN:SETTLING, SAMP:TIMER?
• *RST Condition: Sample Timer for all Channel Lists set to 4.0E-5 seconds.
• Send with VXIplug&play Function: hpe1422_cmd(...)
