GPIB Commands and Queries

³ The FORM:READ:DATA? query does not exist.

³ The MMEM:ACQ:DATA:RECA:VALUE? query should be defined as

follows:

MMEMory:ACQuisition:DATA:RECAll:VALUE?

Description This query returns the measurement saved in the <data>

memory location.

Syntax MMEM:ACQ:DATA:RECA:VALUE?<space><data>

Parameters The <data> parameter represents the memory location where

measurement data is stored (out of the 1024 available).

Response Measurement data saved in the specified memory location in

the “±999.999E±99” format.

Notes

Example MMEM:ACQ:DATA:RECA:VALUE? 1021

³ Use the MMEM:ACQ:DATA:RECA:UNIT? query to get the

corresponding measurement units.

³ Use the MMEM:ACQ:DATA:RECA:WAVE? query to get the

wavelength at which the measurement was taken.

The MMEM:ACQ:DATA:RECA:WAV? query should be named and

³

defined as follows:

MMEMory:ACQuisition:DATA:RECAll:WAVElength?

Description This query returns the wavelength corresponding to the last

value fetched with the MMEM:ACQ:DATA:RECA:VALUE? query.

Syntax MMEM:ACQ:DATA:RECA:WAVE?

Response A wavelength in the “9999 nm” format.

Notes

³ Use the MMEM:ACQ:DATA:RECA:UNIT? query to get the

corresponding measurement units.

³ Use the MMEM:ACQ:DATA:RECA:WAVE? query to get the

wavelength at which the measurement was taken.

Example MMEM:ACQ:DATA:RECA:WAVE?

³ The MMEM:ACQ:SAMP command should be defined as follows:

MMEMory:ACQuisition:SAMPles

Description This command changes the samples parameter for the

acquisition setup.

Syntax MMEM:ACQ:SAMP<space><samples>

Parameters The <samples> parameter is the number of samples to be set

for the acquisition setup. If an invalid parameter is entered, the
closest valid parameter will be entered instead.

Note The duration of the acquisition directly affects the values that

can be set for the number of samples

DxR=S

where

³ D = duration parameter set with the MMEM:ACQ:DURA

command (in seconds)

³ R = any of the possible sampling rates in seconds
