24 CALCulate2 Subsystem
Attribute 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 thresh-
old value. The subtraction is done in dB units. This set-
ting works in conjunction with the peak excursion
setting to determine which responses are located.
Refer
to “:CALCulate2:PEXCursion{?| {<integer> | MINimum |
MAXimum | DEFault}}” on page 5-22
. Changing the
peak threshold limit causes the instrument to reprocess
the current set of data. Refer also to
“To define laser-
line peaks” on page 3-11 .
The query response is the current value. For example, if
the current value is set to 15 dB, the following value is
returned:
15
:CALCulate2:WLIMit[:STATe]{?| {ON | OFF | 1 | 0}}
Turns wavelength limiting on and off.
Attribute Summary
Non-sequential command
Preset State: on
*RST State: on
SCPI Compliance: instrument specific
Description
When this function is on, the Agilent 86121A has an
input range from the WLIMit STARt to the WLIMit
STOP. When this function is off, the instrument displays
peaks over the full wavelength range. The graphics dis-
play always shows the range between WLIMit:STARt
and WLIMit:STOP, regardless of the state of this com-
mand.
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 86121A to wait for non-sequential commands” on
page 4-11
for more information.
