MEASure{:ARRay | [:SCALar]} :POWer:FREQuency?
Returns frequency values.
:POWer:FREQuency? [<expected_value>[,<resolution>]]
Used With <expected_value>
SCALar optional
ARRay
ignored
a. Although ignored, this argument must be present if the resolution argument is specified.
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-wavelength
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. MINi-
mum 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.
MAXimum The highest frequency signal
MINimum The lowest frequency signal
DEFault The current marker position
