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?

to 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)
