Setting the Measurement Time Out
The measurement time-out is the time allowed for each measurement to
complete. If a measurement does not complete before the time out expires,
9.91E37 (not a number) is returned and the display indication is: - - - - - - -.
The sequence continues with the next reading in the sample count.
Specifying a time out prevents the instrument from pausing indefinitely if for
some reason a measurement is unable to complete.
The measurement time out is set with the command:
SYSTem:TIMeout {<time>|MINimum|MAXimum|INFinity|DEFault}
SYSTem:TIMeout? [{MINimum|MAXimum|DEFault}]
(query form)
- time is the specified time out in the range of 10 ms to 2,000s with 1 ms
resolution. The time out setting can affect reading throughput when multiple
readings are taken during the trigger cycle. Trigger delays, gate times, and gate
delays (Chapter 5) should be considered when setting an optimum time out
value.
The time out setting is stored in non-volatile memory and is not changed fol-
lowing a reset (*RST) or instrument preset (SYSTem:PREset or Preset key).
