How to save data from the network analyzer and replot it using matlab:

 

 

Data saving from the HP8510c network analyzer to disk:

1. Use a DOS formatted floppy.

  1. On AUXILLARY menu, press DISC.
  2. STORE. More. Data - DATA (will be calibrated) or RAW (will be uncalibrated, generally don't use this one)
  3. This will bring an ABCDEF .. line, prompting for filename. Use the thumb wheel to move to letters, press SELECT LETTER, press Store.

 

To use matlab to convert data to readable format:

Main.m:

Runs the whole program.

Specify your filename (which you saved in 4. above) and the Sij parameter you want (see main.m) .

Then type: main

 

The function hp8510c strips the header from the file, computes S11,S21, etc. and the frequencies at which this data is given. The S11, S21, etc. will be returned as arrays of complex (real and imaginary) values. The frequency is in Hz.

 

The next function (fdata) converts the complex S parameters to log-mag of S11 (ldata), linear magnitude of VSWR (vdata), and the phase of S11 (pdata). You can add other capabilities to this function, too. See fdata.m
