Signal Generation – The SOURce Subsystem

Measurement Operations & Settings

command:

[:SOURce[n]][:CHANnel[m]]:READout:DATA?

 

syntax:

[:SOURce[n]][:CHANnel[m]:READout:DATA?

description:

Returns the data as a binary stream from either a lambda logging operation or the maximum

 

power the laser can produce at each wavelength.

parameters:

LLOGging:

Returns a binary stream that contains each wavelength step of the lambda

 

 

logging operation, see

 

 

“[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging” on page 140.

 

 

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 pro-

 

 

duce 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.

response:

A binary stream in Intel byte order.

example:

sour2:read:data? llog → the data as a binary stream

affects:

All tunable laser and DFB source modules

 

 

 

 

 

 

command:

[:SOURce[n]][:CHANnel[m]]:READout:DATA:BLOCk?

 

syntax:

[:SOURce[n]][:CHANnel[m]:READout:DATA:BLOCk?<wsp>LLOGgingPMAX,<offset>,<# of

 

data points>

 

description:

Returns a specified binary block from either a lambda logging operation, or maximum power

 

at wavelength characteristic.

parameters:

LLOGging:

Returns the data block from lambda logging. The binary block is an 8-

 

 

byte long double in Intel byte order.

 

PMAX:

Returns the data block from the power curve characteristic. 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.

 

<offset>

A zero based offset that specifies the index of the first value within the

 

 

block to be transferred.

 

<# of data points> The number of points (not bytes!) in the transferred block.

response:

A binary stream in Intel byte order.

example:

sour0:read:data:block? llog,100,20000 → the data as a binary stream

affects:

All tunable laser and DFB source modules

affects:

[:SOURce[n]][:CHANnel[m]]:READout:DATA:MAXBlocksize?

[:SOURce[n]][:CHANnel[m]:READout:DATA:MAXBlocksize?

Returns the maximum block size for a single GPIB transfer for lambda logging functions. If your application requires more data points please use SOURce[n]][:CHANnel[m]]:READ- out:DATA:BLOCk? instead of SOURce[n]][:CHANnel[m]]:READout:DATA?

none

The maximum number of data points (not bytes!) in the transferred block, as an integer value. sour0:read:data:maxb? → 120<END>

All tunable laser and DFB source modules
