Summary
Non-sequential command
Preset State: 10 dB
*RST State: 10 dB
SCPI Compliance: instrument specific
Description A laser line is identified as a valid peak if its amplitude is above the
maximum amplitude minus the peak threshold value. The subtraction
is done in dB units. This setting works in conjunction with the peak
excursion setting to determine which responses are located. Refer to
“PEXCursion” on page 4-33. Changing the peak threshold limit causes
the instrument to reprocess the current set of data. Refer also to
“Defining Laser-Line Peaks” on page 2-15.
The query response is the current value. For example, if the current
value is set to 15 dB, the following value is returned:
15
PWAVerage[:STATe]
Places the instrument in the power- weighted average mode.
Syntax
:CALCulate2:PWAVerage[:STATe]{?| {ON | OFF | 1 | 0}}

Summary
Preset State: off
*RST State: off
Description When the state is on, the CALC2:DATA? POW query returns the total
power and the CALC2:DATA? WAV, FREQ, or WNUM query returns the
power-weighted average wavelength, frequency, or wave number val-
ues.
Non-sequential command
Always use an *OPC? query or a *WAI command to ensure that this command has
the time to complete before sending any more commands to the instrument. Refer
to “Always force the Agilent 86120C to wait for non-sequential commands” on
page 3-12 for more information.
