Generate a '2 output instrument' directive to IVI driver

[malosh]

Hi,

 I have a Tektronix AWG420 which I didn't find drivers for anywhere; however I did find an IVI driver for the AWG5x0 family in the NI drivers' zone.

As the command set for these instruments is almost identical I tried using it, and it works great with my applications for Channel1 if I turn of the 'ID query' at initialization.

 

However, as the driver doesn't recognize that I have a 2-output instrument I can't communicate with Channel2.

Does anyone know how can I give directives to the driver that this is a 2-output instrument?

Thank a lot,

Unless you want to buy LabWindows/CVI and modify the driver (orf ind someone to do it for you), I think your only option is to use tkawg5x0 Write Instrument Data to send the unsupported commands. This (and a read function) are on the Utility Functions>Instrument I/O palette.

Since doing this makes your program instrument specific and you lose most of the reasons for using IVI, you could always write a native LabVIEW driver or use the Instrument I/O Assistant instead of the IVI driver.
