How I can delete the interruption in my VI to control My Signal Generator

[vanny]

Dennis Knutson can u respond to other question in my first post?

IMPORTANT: Now I can assign to my instrument a frequency and amplitude. But after assignment the program go off. and I can put other value and run the program again. But If I desire that my program is run always so I can change in real time the values... how can do it?

please have a look at the attached example.

You've got too many questions in too many other threads and I have no idea what 'other question' you are refering to.

To have something run continuously, you need a while loop. I would recomend that you use an event structure inside one and use a value change event to send a command whenever the front panel control changes.

juergenstraub thanks very much!!!! What is the difference between ASRL and GPIB??

What is the selection frame? Where I can choose between NBO, NB All, user, Edge 0, Edge All, GSM Edge?

You should edit the initialize function and get rid of 'Old VISA Open'. That will mean deleting the string with the visa name in it and connecting the VISA session control to the connector pane where the string was.

I have no idea what version of LabVIEW you are now using. If you would provide that, I could perhaps send you the modified VI.

Time to hit <ctrl>-H

This gives you access to the VI descriptions and the LabVIEW help file.  Also, many examples exist in the Example folder (browse the examples) these are a good resource to help answer this type of question.

ASRL is a Serial port resource

GPIB is a resource on the General Purpose Instrumentation Bus.

They have different settable properties so the default VISA alias displays a mnemonic to aid the developer

[juergenstraub]

this is just a simple example... you have to programm your own functionality using the RSSMIQ VIs. see jpeg

I have another problems!

See the Figure:

1) In the upper figure I have used the Control to Instrument Descriptor. In the second figure (down) I have only Used a String costant with the same words that the control had. Why in the second case compare a error Message? I have post also the type of error.

2) In the figure down:

I don't understand the logic od LabVIEW. There are 3 yellow icon: first from left for Forward mode, Second reverse mode and the last pass the results to the indicator. But... what is the logic? How can the first yellow icon pass the result to the third icon? And if there is a consequently action... if a set in forward mode, after in revers and after misureament... i can't read the forward measurment.

Can u explain the logical steps to write the measurements???

Associate respons to number of my question please... so I understand.

Hi vanny,

have you tried Ctrl-H on those icons?

These icons represent different functions of your device driver library.

The first two are used for setting operation modes of your device (used for configuration). The 3rd one does the actual measurement...

Please (try to) use the standard debugging features of LabView:

- switch on the context help

- use highlighted execution

- use probes

- look into those device driver functions

- use execution in stepping mode

- RTFM
