Measurement Operations & Settings Signal Generation The SOURce Subsystem
130 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
command: [:SOURce[n]][:CHANnel[m]]:READout:POINts?
syntax: [:SOURce[n]][:CHANnel[m]:READout:POINts?<wsp>LLOGging|PMAX
description: Returns the number of datapoints that the [:SOURce[n]][:CHANnel[m]]:READout:DATA? com-
mand will return.
parameters: LLOGg ing:
PMAX:
Returns the number of wavelength steps for a lambda logging operation, see
[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging” on page 140.
Returns the number of datapoints (ea ch datapoint contains a value f or wave-
length and power) the [:SOURce[n]][:CHANnel[m]]: READout:DATA? PMAX
command will return, num ber of datapoints dep ends on the calibrati on data
for your module.
response: The number of datapoints as an integer value.
example: sour2:read :poin? pmax 120<END>
affects: All tunable laser and DFB source modules
command: [:SOURce[ n]][:CHANnel[m]]:WAVelength[:CW[l]:FIXED[l]]
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength[ :CW[l]:FIXED[l]]<wsp><value>
[PM|NM|UM|MM|M]
description: Sets the absolute wavelength o f the output.
parameters: Any wavelength in the specified ran ge (see the specifications in the appropriate User’s
Guide).
The progra mmable range is lar ger tha n the ra nge sp ecified in the User’s Guide. The program-
mable range is set individually for each instrument when it is calibrated during production.
Also allowed are: MIN: minimum wavelength value
MAX: maximum wavelength value
DEF: This is not the preset (*RS T) defau lt value but is half the sum
of, the minimum wavelength value an d the maximum wavelength
value
NOTE Use [l] to set the upper or lower waveleng th laser source of a dual-wavelength la ser source.
The default value of [l] is 1, the lower wavelength sourc e. The upper wave length source is
denoted by2.
response: none
example: sour2 :wav 1550NM
affects: All tunable laser and DFB source modules
