I try to communicate with SCPI commands to an instrument.
I've done a visa command to send it instruction.
The instrument is composed with 4 slots, and the slot 1-0 had 4 channel
So with the following VI, I succed to communicate with the instrument with sending the following instruction " lins10 : READ : SCALar : POW: DC?"
The instrument returns me the value of the slot 1-0 Channel 1
ti read the other channel (C1 to C4), i've try to send: différents commands:
lins10: SOURce C1: READ: SCALar: POW: DC
lins10: SENSe C1: READ: SCALar: POW : DC
lins10: FETCh C1: READ: SCALar: POW: DC
lins10: INPut C1: READ: SCALar: POW: DC
with différents name: C1; Channel1 ; 1 etc...
so someone should tell me how can I do , or the good command to use please.
Thank you for your responses
Solved! Go to Solution.
It's a modular Platform. The device is an EXFO; model IQS 600
iqs 600 is a Windows 10 Platform.
Data acquisition card is a IQS 1740. This is a card to measure optical power transmitted in optical fiber câble.
you can see this instrument in this photo
I think you want to do the following..
I'd make a subvi that takes both the logical instrument position (eg. 10) channel number (1-4) as an input, appends it to the READ, then appends the other part and querries the instrument and returns the result.
Same thing if you use FETCH..
Those other commands you list don't seem to be valid SCPI commands for the instrument.
Hope that helps.
Thank you for your help
The following instruction works ; LINS10 : READ 3: SCAL : POW : DC ? and with read 1-4
you solved my problem and i can advance in my project
