Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 161
command:
:CONFigure[n][:CHANnel[m]]:OFFSet:WAVelength:VALue
syntax:
:CONFigure[n]][:CHANnel[m]]:OFFSet:WAVelength:VALue<wsp><lambda>[PM | NM | UM | MM|
M],<offset[DB]> | TOREF
description: Adds a value pair (wavelength; offset) to the offset table, or overwrites an existing value pair.
The offset table entries are ordered from shortest to longest wavelength.
parameters: <lambda>
<offset>
TOREF
The wavelength for the offset table entry, in m
The power offset to be applied at <lambda>.
To query the current power value measured by attenuator with power control
see page 87 (Fetch) and page 90 (Read).
Calculates the difference between the power measured by an external power-
meter (hosted in the same mainframe) and the power measured by the attenu-
ator module’s integrated powermeter, and stores it as the offset.

(Attenuator modules with power control only).
response: none
example: CONF1:OFFS:WAV:VAL +1.55000000E-006,TOREF
affects: All attenuator modules (TOREF applicable to attenuator modules with power control only).
command:
:CONFigure[n][:CHANnel[m]]:OFFSet:WAVelength:REFerence
syntax: :CONFigure[n]][:CHANnel[m]]:OFFSet:WAVelength:REFerence<wsp><slot>,<channel>
description: Specifies the slot and channel of the external powermeter (hosted in the same mainframe as
the attenuator module) used by TOREF.
See: “:CONFigure[n][:CHANnel[m]]:OFFSet:WAVelength:VALue” on page 161
parameters: <slot>
<channel>
Slot number of the powermeter.
Channel number of the powermeter.
response: none
example: CONF1:OFFS:WAV:REF 4,2
affects: Attenuator modules with power control.
