[:SOURce[n]][:CHANnel[m]]:POWer:WAVelength?
[:SOURce[n]][:CHANnel[m]:POWer:WAVelength?
For compatibility reasons, WAVelength may be replaced with WAVE.
Returns the wavelength source for a dual-wavelength laser source.

[:SOURce[n]][:CHANnel[m]]:READout:DATA?
[:SOURce[n]][:CHANnel[m]:READout:DATA?
Returns the data as a binary stream from either a lambda logging operation or the maxi-
mum power the laser can produce at each wavelength.
LLOGging: Returns a binary stream that contains each wavelength step of the lambda
logging operation, see "[:SOURce[n]][:CHANnel[m]]:WAVe-
length:SWEep:LLOGging" on page 111. Each binary block is an 8-byte long
double in Intel byte order.
PMAX: Returns a binary stream that contains the maximum power the laser can
produce at each wavelength. Each binary block is a 8-byte long double (the
wavelength value) followed by a 4-byte long float (the power value). The
stream is in Intel byte order.
A binary stream in Intel byte order.

All tunable laser and DFB source modules
[:SOURce[n]][:CHANnel[m]]:READout:POINts?
[:SOURce[n]][:CHANnel[m]:READout:POINts?<wsp>LLOGging|PMAX
Returns the number of datapoints that the [:SOURce[n]][:CHANnel[m]]:READout:DATA?
command will return.
LLOGging: Returns the number of wavelength steps for a lambda logging operation,
see "[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging" on
page 111.
PMAX: 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 calibra-
tion data for your module.
The number of datapoints as an integer value.
