communicating with LO module software

[nesha]

Hi,

I have an LO generator that is control with a piece of software through the USB port. There is a slide bar that is used to set the frequency and

a button to turn the RF ON\OFF

I am in the process of programming my application using LabView and I would like to know how to communicate with this piece of software

so that I can change the frequency programmatically.

Thank You

The LO is a bench top frequency generator. The slide bar is used to set the frequency of this generator. For example, a test signal  of 1860 Mhz is needed.

To set this frequency, I would simply slide this bar to 1860 Mhz.

Thank You

You still haven't provide much information. What's the make and model of this instrument? Are you trying to control the instrument directly or trying to interface to a program that the vendor provides? It kind of sounds like you are trying to interface to the vendor's program. If so, you need to contact the vendor to see what, if any, provision they have made for control by a third party program. See if they have an ActiveX interface, for example. Otherwise, see if they provide documentation on direct control of the instrument. They may have a LabVIEW driver or if they have a dll, a published api that you cann use with the Call Library Function Node.
