I don't want any signal after running the initialize.vi on a HP33120A

[Gert.vi]

Hello,

I want to use GPIB/Labview to control the Agilent Function generator HP33120A.

First problem is that you need to run the initialize.vi, that vi resulting in a small signal, but I don't want anything on the output at that moment.

Best regards,

Gert

Hello,

Without knowing the contents of initialize.vi its not possibel to help you.

Post the VI or a screenshot of the blockdiagram.

Here a screendump:

I used the original labview-driver for the Agilent 33120A from the labview.com-website

Hello,

There are a number of things you could try.

1. When using the initialize.vi try the "Reset device" option "False".
2. Use the initialize with options.vi directly and customize the option string, the link below explains the different options.

IVI Benefits and Features

If this brings no solutions, maybe some else could help you out.

Kind regards,

I already played with these things, without succes. None of these options remove the signal you have after initialize.

Gert,

Please describe exactly what kind of signal you get after running Initialize. What do you need to do to get a similar signal if you run the instrument manually?

I have seen some instruments which produce a small offset or some signal feedthrough when they are in the Output Disabled state whether manual or GPIB control. You may be better off programming a signal with minimum amplitude immediately after initializing rather than having the instrument in the disable mode.

Also, instead of using the IVI driver, you can try the LabVIEW one. The initialize function in the LabVIEW driver may behave the same way but at least you can view the code and modify it if you want.
