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? command will return.
parameters:
LLOGging:
PMAX:
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 of the output.
parameters:
Any wavelength in the specified range (see the specifications in the appropriate User's Guide).
The programmable range is larger than the range specified in the User's Guide. The programmable range is set individually
for each instrument when it is calibrated during production.
Also allowed are:
Use [l] to set the upper or lower wavelength laser source of a dual-wavelength laser source. The default value of [l] is 1, the
lower wavelength source. The upper wavelength source is denoted by 2. For 81950A, only available in "Auto Mode". "CW"
and "Fixed" are just present for backwards compatibility.
response:
none
example:
sour2:wav 1550NM
affects:
All tunable laser including 81950A and DFB source modules
8163A/B, 8164A/B & 8166A/B Mainframes Programming Guide
Returns the number of wavelength steps for a lambda logging operation, see
page 170.
Returns the number of datapoints (each datapoint contains a value for wavelength and power) the
[:SOURce[n]][:CHANnel[m]]:READout:DATA? PMAX command will return, number of datapoints depends
on the calibration data for your module.
MIN: minimum wavelength value
MAX: maximum wavelength value
DEF: This is not the preset (*RST) default value but is half the sum of, the minimum
wavelength value and the maximum wavelength value
