Chapter 4 Command Reference

:MEASure Subsystem

Programming Guide 4-15

COMMAND :READ?[[:SCALar]:<function>]?

This query provides a method for performing a :FETCh? on fresh data.

COMMENTS • This command is commonly used in conjunction with a :CONFigure

command to provide a capability similar to :MEASure?, in which the

application programmer is allowed to provide fine adjustments to the

instrument state by issuing the corresponding commands between

:CONFigure and :READ?.

• When [:SCALar]:<function> is specified, the instrument retrieves the

specified result if it matches the current measurement type or can be

derived from the current measurement type.

• When [:SCALar]:<function> is omitted, the function specified/used by

the last :CONFigure, :MEASure, :READ, or FETCh is used, if possible.

• Issuing this query while a measurement is in progress aborts the

current measurement and idles the measurement cycle before

initiating the desired measurement. The Counter then waits for the

measurement to complete. This has the effect of holding off processing

of further commands until the desired measurement completes.

This hold-off action can be canceled only by the completion of the

measurement, Device Clear, or power-on.

• If an <expected_value> parameter is outside the measurement

capabilities of the Counter model, an error is generated, and the

command does not execute.

• For :POWer, <resolution> must be defaulted or set to 0.01[dB].

• See “Descriptions of the Measurement Functions” on Page 4-16 for a

description of each of the measurement functions.

• Refer to Table 4-2 for a summary of the <function>, <parameters>,

and <source_list> for each of the measurement functions.
