Aquire S parameter data from VNA

[jkerekes]

We recently purchased Measure and the PCI-GPIB card, and I'm new to data aquisition. I want to output swept frequency S parameter data from a network anaylzer, specficially an HP8510 using a 201 point sweep. I want to be able to read the S para and freq values of each point in the sweep for Excel storage and plotting of the data. I'm having a couple of problems.
1) Measure reads only the S para value of the first sweep point no matter how large the range is.
2) How do I read the freqeuncy values of the corresponding sweep points?

I have found the answer to the first part of my question on the Measure Support page, under the "Parsing Issues with Measure" link.

I have also found a work around for the frequencies. The 8510 will output the Start, Stop and Number of Points for the sweep by using the OUTPACTI command. With these 3 variables, the frequency points can be calculated in Excel.

If anyone knows of a more direct way to output the frequencies, I would appreciate the advice!
