Error generated by remote interface

[Sam59]

Hi, 

The problem is the following.

I am trying to control a 33250A Function generator via GPIB and Labview. I downloaded the library äg33xxx" form NI website.

The "Getting Started"vi is working well, but I am not able to use the "Config Pulse.vi" to change duty cycle or Pulse width of a pulse.

If I try to send a command from the "Config Pulse.vi", I get this message on the 33250A:

Error generated by remote interface command.

Has somebody any idea about this problem?

Thank you.

Regards.

Samuel.

Hi, 1. First of all, check if no error is generated by LabVIEW itself. Check the error clusters. 2. Track down the command string that gets generated by the VIs from the instrument driver. Check if the string matches exactly the command that can be accepted by your device. All these commands should registered in the manual of your device. If not, please contact the provider. It could be that the string that is being generated by the Config_Pulse.vi doesn't match the one from the manual. Please verify. Regards. JorisV

Hello all.

I found the error on the command sent by Labview to the 33250A.

By replacing "FUNC" by "SOUR" in the vi, the command is ok, and I am able to change the Pulse Width.

I did not spend time to understand excatly the problem, but I have at least its solution.

JorisV, thank you for support.

The instrument driver group has looked into your post, and we have filed a bug report against the driver.  The driver supports models 33120, 33220, and 33250.  The commands in Config Pulse were mistakenly implemented using the 33220 manual without cross-referencing the 33250 manual.  The driver will be updated and re-released to IDnet in the near future.

Thanks for your post.

I've downloaded the same drivers and I'm unsure how to change the pulse width on a given frequency waveform. I've set the Waveform Shape to "Pulse" in ag3xxx - Config Waveform.vi, but I see no VI to actually adjust the pulse width. Is it in the VI "ag3xxx - Config pulse.vi"? It's not obvious if it is.

Thanks,

Mike
