Programming Commands

CALCulate2 Subsystem

When there is no input signal, the POWer query returns –200 dBm; the WAVelength query returns 100 nm (1.0E–7).

PEXCursion

Sets the peak excursion limit used by the Agilent 86120C to determine valid laser line peaks.

Syntax

: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

Attribute

Non- sequential command

Summary

Preset State: 15 dB

 

*RST State: 15 dB

 

SCPI Compliance: instrument specific

Description

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 min-

 

ima on either side of the peak. This command works in conjunction

 

with the peak threshold setting. Refer to “PTHReshold” on page 4- 34.

 

Changing the peak excursion 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
