CALCulate2 Subsystem
PEXCursion
Sets the peak excursion limit used by the Keysight 86120B to determine valid laser
line peaks.
:CALCulate2:PEXCursion{?| {<integer> | MINimum | MAXimum | DEFault}}
<integer> represents logarithmic units in dB. Valid range is 1 to 30 dB.
Constant
Description
MINimum
1 dB
MAXimum
30 dB
DEFault
15 dB
Non-sequential command
Preset State: 15 dB
*RST State: 15 dB
SCPI Compliance: instrument specific
A laser line is identified as a valid peak if its amplitude is greater than the peak
excursion plus the amplitudes of the closest local minima on either side of the peak.
This command works in conjunction with the peak threshold setting.

The query response is the current value. For example, if the current value is set to 15
dB, the following value is returned:

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.
