3.18 Sense subsystems
The Sense subsystems are used to configure and control the measurement functions (Sense 1)
and to read the digital input port (Sense 2). The commands for the Sense subsystems are sum-
marized in Table 3-10.
[:SENSe[1]] subsystem
This Sense 1 Subsystem is used to configure and control the measurement functions of the
Model 2002. Keep in mind that a function does not have to be selected in order to program its
various configurations. When the function is later selected, it assumes the programmed states.
:ALTernate[1] commands
:SAVE
[:SENSe[1]]:ALTernate[1]:SAVE Save Alternate setup.
This command is used to save the current instrument setup as the Alternate setup. The instru-
ment can be returned to the Alternate setup by using the :ALTernate[1]:RECall command.
An Alternate setup can be used as the function parameter for a scan (see :ROUTe :SCAN).
PRINT #1, "output 16; :alt:save" ' Save present setup as alternate setup
:RECall
[:SENSe[1]]:ALTernate[1]:RECall Return to Alternate setup.
This command is used to return the instrument to an Alternate setup (see :ALTernate[1]:SAVE).
If there is no Alternate setup currently saved, this command is a No-Op (no operation).
PRINT #1, "output 16; :alt:rec" ' Recall alternate setup
:FUNCtion <name>
[:SENSe[1]]:FUNCtion <name> Select measurement function.
<name> = ‘VOLTage:AC’ Select ACV
‘VOLTage:DC’ Select DCV
‘RESistance’ Select Ω2
‘FRESistance’ Select Ω4
‘CURRent:AC’ Select ACI
‘CURRent:DC’ Select DCI
‘FREQuency’ Select FREQ
‘TEMPerature’ Select TEMP
:FUNCtion? Query currently programmed function.
