a. Although ignored, this argument must be present if the resolution argument is specified.

Description When used with a :SCALar command, a single value is returned. The display is placed in the single- wavelength mode, and the marker is placed on the signal having a frequency that is closest to the <expected_value> parameter. Default units for <expected_value> parameter are in Hz. When used with an :ARRay command, an array of frequencies is returned. The display is placed in the list- by- wave- length mode.

The <resolution> parameter sets the resolution of the measurement. It is a unitless number whose value will be limited to either 0.01 or 0.001 (whichever is closer). MAXimum resolution is equivalent to the FAST measurement update mode. MINimum resolution is equivalent to the NORMAL measurement update mode.

Returned values are in Hz (display is in THz). Power units are not affected.

CONFigure command

When this function is used with the CONFigure command, the query question mark character “?” must not be included in the string. However, the FETCh, READ, and MEASure command are queries and require the question mark. Refer to the examples for this command.

<expected_value> MAXimum

The highest frequency signal

Constants

MINimum

The lowest frequency signal
