GPIB to spectrum analyzer E4440A reading

[*E*]

I have a PCI-GPIB that i need to communicate with an E4440A spectrum analyzer. I already installed the instrument driver and MAX . How do i read in the measurements reading thats on my spectrum analyzer in to my labview program and display the measurement and a graph?

See whether this will give you an idea

Thank you. But Im not trying to take any type of measurements or anything all im trying to do is read in whats on the spectrum analyzer in the form of a graph and the measurement value it self.

Sorry, but that statement does not make much sense to me. You don't want to take a measurement but you do want to read a measurement? The two seem to be identical to me.

In any case, open the example finder and go to Hardware Input and Output>Instrument DriversLabVIEW Plug and Play. The 'Agilent ESA PSA... examples demonstrate some of the functions in the driver. Several of them read the trace data and display it on a graph.

What I said was im not trying to take  control  or  measure anything from my labview program that will be done on the instrument it self. What I need to do is reading in the data thats on the instruments in to my labview program.

Well, I would define reading the data from the instrument as taking a measurement - whether you initiate the measurement manually or programatically. The read function is identical.

Hello *E*,

I'm sure there are some examples included with the driver that allow you to take measurements.  I know you mentioned you didn't want to take control of the device, but in order to be able to read the information from it you must specify what device you are referring to, and then send the command to the device to receive the measurement.  From there, you can take the response from the device and plot that on a graph.
