Measurement Instructions (:CONFigure, :FETCh, :MEASure, :READ)

How to Use the Measurement Instruction Commands (Cont.)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 now it is possible to insert commands between :CONFigure and :READ? to specify a particular setting. For example, use

:CONF:FREQ 5 MHZ, 1HZ

to configure a default frequency measurement where 1 Hz is the required resolution and 5 MHz is the expected value.

Use

:SENS:EVEN:LEV 0V

to set the trigger level to 0 Volts.

Use

:READ?

to start the measurement and query the result.

Using :CONFigure with :INITiate and :FETCh?

The :READ? query is composed of the :INITiate command, which starts the measurement, and the :FETCh? command, which returns the results to the controller. For example, use

:CONF:FREQ 50 MHZ, 1 HZ

to configure for a default frequency measurement where 1 Hz is the required resolution and 50 MHz is the expected value.
