:FPAV?
Description
Queries the Fabry-Perot calculation method state.
Query Response
{ON | OFF}
Examples
:CALC2:FPAV?
:FPAV{ON | OFF}
Description
Sets the Fabry-Perot calculation method to ON or OFF. If ON, the
wavelength is calculated as the weighted average of all spectral peaks
and the power is the total power of all spectral peaks. This function is
useful for characterizing the central wavelength and total power of multi-
mode FP lasers.
*RST value
OFF
Examples
:CALC2:FPAV ON
:AVERage[:STATe]?
Description
Queries the state of the spectral averaging.
Query Response
{ON | OFF}
Examples
:CALC2:AVER{:STATe}?
:AVERage[:STATe] {:ON | :OFF}
Description
Turns spectral averaging ON or OFF. Determines the number of scans
used to calculate wavelength and power when the average function is
enabled. The choices are 2, 4, 8, 16, 32, 64, or 128.
When average is on, the interferograms from the selected number of
averages are collected and averaged before any measurements are
computed and displayed.
*RST value
OFF
Examples
:CALC2:AVER ON
:CALC2:AVER:STAT ON
:AVERage:COUNt?
Description
Queries the number of scans used to calculate the wavelength and
power when the average function is enabled.
Query Response
{2 | 4 | 8 | 16 | 32 | 64 | 128}
