Remote Control
The measurement procedure using the CONF:VOLT command and READ? query is
flexible in that the measurement conditions can be specified in detail. However,
because the READ? query itself contains the function of the measurement start
command, it is still inflexible in terms of specifying the measurement timing. This is
because, measurement is started every time the READ? query is issued. To program
the measurement timing in detail, the measurement start and data acquisition
procedures must be separated. The commands that allows you to do this are INIT
and FETC?. The READ? query is equivalent to combining the INIT command and
FETCh? query.
4.9.3 Measurement procedure with flexibility (INITiate and
FETCh)
Because the measurement procedure using the INIT command and FETC? query
separates the measurement start and data acquisition procedures, it enables the most
detailed control. INIT is used to start the measurement, and FETC? is used to query
the data of a measurement that has been completed.
Example:
CHAN:VOLT:NSEL 1 ' Select logical channel 1.
SENS:VOLT:RANG 20 ' Set the selected channel
to 20 V range
CHAN:VOLT:NSEL 2 ' Select logical channel 2.
SENS:VOLT:RANG 2 ' Set the selected channel
to 2 V range
INIT ' Start voltage scanning on
all activated channels.
CHAN:VOLT NSEL 1;:FETC? ' Query the measured data
of Ch1.
(Read the response)
CHAN:VOLT:NSEL 2;:FETC? ' Query the measured data
of Ch2.
(Read the response)
The INIT command measures all voltage measurement channels. After sending the
INIT command, you can query the data by specifying an individual channel with the
FETC? query.
