4.5.6 Measurement Function
■
Difference between SCALar and ARRay
The second level node of FETC?, READ?, and MEAS? can be [SCALar] or ARRay.
[SCALar] is the default node that can be omitted and returns the measured data of
the channel specified by CHAN:VOLT:NSEL.
ARRay returns the measured data of all logical channels that are set as scanned
sources for voltage scanning in comma-separated format.
■
Difference between FETC, READ, and MEAS
FETC acquires data that has been measured already without starting the
measurement operation. If you use the FETC? query without initiating the voltage
scanning operation after the measured data has been discarded, an SCPI error (-230,
"Data corrupt or stale") occurs. This is because there is no valid measured data, and
the acquisition of measured data cannot be expected. Be sure to use this command
with the INIT command.
READ starts a new measurement operation and acquires the resultant data. The
READ command is a combination of INIT and FETC.
MEAS resets the settings to default, starts a new measurement operation, and
acquires the resultant data. The MEAS command is a combination of ABOR,
CONF, and READ.
FETC
FETC:ARR
Queries the voltage measurement data.
Command
FETCh[:SCALaar][:VOLTage[:DC]]?
FETCh:ARRay[:VOLTage[:DC]]?
Response
Returns the measured data in the <NR3> form in response to FETC?.
Returns the measured data in the <NR3>, <NR3>... form in response to
FETC:ARR?.
