Hello,

Hello,

I'm very new to LabVIEW. I'm trying to control keithley 6221 using RS-232.

What I want to do is just to change the frequency of a sine wave at every 30 seconds, and the series of the required frequencies could be input at the beginning.

Does anybody know how can I do it?

I'll be glad to get any help.

Thanks!

NI does not have a LabVIEW driver for that instrument but you might want to check with Keithley.

On the main Instrument Driver Network page are links on developing an instrument driver. There is a wizard (Tools>Instrumentation>Create Instrument Driver Project) as well as the Instrument I/O Assistant. You will need the instrument manual to look up the programming commands. There are example VIs for serial communication.
