Chapter 4 Command Reference
:MEASure Subsystem
Using :MEAsure
This is the simplest Measurement Instruction command to use, but it does
not offer much flexibility. :MEASure causes the Counter to configure
itself for a default measurement, starts the measurement, and queries the
result. The following example shows how to use the :MEASure query to
measure frequency.
Use
:MEASURE:FREQ?
t o execute a default frequency measurement and have the result sent to
the controller. The Counter selects settings and carries out the required
measurement; it automatically starts the measurement and sends the
result to the controller.
You can add parameters to provide more details about the signal you are
going to measure.
Use
:MEASURE:FREQ? 50 MHZ, 1 HZ
where 50 MHz is the expected value (this value can also be sent as
50E6 HZ), and 1Hz is the required resolution.
The channel numbers can also be specified. For example, you can send:
:MEASURE:FREQ? (@1)
:MEASURE:FREQ? 50 MHz, 1 HZ, (@1)
Using :CONFigure with :READ?
The :CONFigure command causes the instrument to choose default
settings for the specified measurement. :READ? starts the measurement
and queries the result.
This sequence operates in the same way as the :MEASure query, but it
allows you to insert commands between :CONFigure and :READ? to
specify a particular setting.
