Table 4-1. Summary of the Measurement Instruction Commands

The <source_list> parameter has the same syntax as SCPI <channel_list>.

For example, the Frequency function uses (@1) to specify channel 1.

If the instrument receives an unexpected parameter, it processes the

command, ignoring the unexpected parameter, and sets the “Command

Warning” bit of the Data Questionable status reporting structure.

The response format for :MEASure query, :READ?, and :FETCh? is ASCII

data. If no valid data is available, the Counter generates error -230

(Data corrupt or stale).

Command Description

:MEASure query This command is the simplest to use, but it allows little flexibility.

This command lets the Counter configure itself for an optimal

measurement, initiate the measurement, and return the result;

i.e., it provides a complete measurement sequence (:MEAS query is

equivalent to the :CONF, :INIT, :FETC? command sequence, but

with no flexibility.)

:CONFigure

:READ?

The combined use of these two commands allows for more control

when the Counter performs a measurement, initiates a

measurement, and returns the result. Use this command sequence

when you want to customize the configuration between the

measurement setup and acquisition.

:CONFigure

:INITiate

:FETCh?

This combination of commands provides the most flexibility the

Measure Instructions allow. This command sequence configures the

Counter, initiates the measurement as specified, and returns the result.
