Number of Samples
Normally, the meter takes one reading (or sample) each time it receives
a trigger from the selected trigger source (if the meter is in the
wait-for-trigger state). You can, however, instruct the meter to take
multiple readings for each trigger received.
•
Number of samples: 1 to 50,000. The default is 1 sample per trigger.
•
The sample count is stored in volatile memory; the meter sets the
sample count to 1 when power has been off or after a remote interface
reset. The CONFigure and MEASure? commands automatically set
the sample count to 1.
•
Front Panel operation: set the number of samples per trigger in the
3: N SAMPLES
command under the TRIGger menu.
•
Remote operation: use the following command:
SAMPle:COUNt {<
value >|MIN|MAX}
Number of Triggers
Normally, the meter will accept only one trigger before returning to the
“idle” trigger state. You can, however, instruct the meter to accept
multiple triggers.
This feature is available only from the remote interface. If you set the
trigger count and then go to local (front panel), the meter ignores the
trigger count setting; when you return to remote, the trigger count returns
to the value you selected.
•
The selected number of triggers is stored in volatile memory; the
meter sets the trigger count to 1 when power has been off or after a
remote interface reset or preset. The CONFigure and MEASure?
commands automatically set the trigger count to 1.
•
The number of triggers can be set to any number between 1 (MIN) and
50000 (MAX) or can be set to be INFinity. When the trigger count is
set to be infinite, use the READ? command to collect the readings.
Send a device clear to stop the measurements.
See page 187 for
information about device clear.
