[:Sense] Subsystem; [:Sense]:Event[1|2] Subtree - HP 53131A/132A 225 MHz Programming Manual

Chapter 4 Command Reference

[:SENSe] Subsystem

[:SENSe] Subsystem
The [:SENSe] subsystem commands are divided into several sections. Each
section or subtree deals with controls that directly affect
instrument-specific settings and not those related to the signal-oriented
characteristics.
[:SENSe]:DATA? ["[:]SENSe[1]"]
Queries the current measurement result data of the :SENSe subsystem (no scale or
offset applied).
If this query executes while a measurement is in progress, then the prior
measurement result will be returned, if the prior result has not been invalidated.
Query Response
Comments
Query only.

[:SENSe]:EVENt[1|2] Subtree

This subtree defines the "trigger event."
For Frequency, this is the event which is counted; for Time Interval, this is the
start/stop edge.
These trigger events are fed to the sensor function. In separate, the EVENt1
subtree is fed the INPut1 signal and the :EVENt2 subtree is fed the INPut2 signal;
in common, the INPut1 signal is fed to both the EVENt1 and :EVENt2 subtrees.
When you are measuring Voltage Peaks, none of the :SENSe:EVENt settings are
used.
4-80
Result will be formatted according to :FORMat[:DATA] ASCii | REAL
setting.
When ASCii format is used, numeric data is transferred as ASCII bytes in
<NR3> format. The number of significant digits will range from 1 to 15
depending on the measurement resolution.
If no valid result exists, Not a Number 9.91E37 is returned and error -230 is
generated.
If this query is executed while an automatically armed Totalize measurement
is in progress, Not a Number 9.91E37 is returned and error -221 is
generated. :ABORt should be used to terminate the measurement and avoid
this error.
