Draw a graph from the S-parameters network analyser results

[jim85]

Hi Guys,

I have a problem with the drawing x and y axis graph from the Agilent 8720ES S-paramters network analyser marker results. The results are created by the analyser in a given time. I want those results to save in my VI and retrive together to draw a graph.

I dont know how to save it and take back the results together. Can anyone help me with this? I have attached my VI with this mail.

Regards

Jim

There is a driver for the 8720 if you goto Help--> Find Instrument Drivers. There is an example that does what you requested only graphing the entire sweep not just the points.

I don't have an 8720 but I have a 8510B. With the 8510 at least you have to specifically request the power and frequency pairs seperate. Something like -

MARK1; OUTPACTI;

READ <-- Gives you the frequency location of the point.

OUTPMARK

READ <-- Gives you the power at that point.

I then build an array with the pairs. Sorry I don't have a labview example I'm still migrating much of my code from VB.NET.
