My inferences were based on the file attached and what I saw when I looked at the code.

My question was about your attempt to use the undocumented DIAG command.  You could use the old DOS Debug command.    Another option would be to load up a different debugger or just use the built in Agilent tools.   But again, my PNA has no additional hardware.


Forzaman, can you zip all of your cal files and post them?  You may need to do two posts.

Sure, no problem. If you are referring to the files in D:\calfiles, I just have four files; mxcalfile_r4p12, mxcalfile_r4p21, eebudat.dat, eebudat.bak. Is this what you want?

From the service manual, it appears that they stored them in two separate locations. 


--- Quote ---copy all files that are prefixed with mxcalfile_ in the C:/Program Files/Agilent/Network Analyzer directory
--- End quote ---

--- Quote ---The mxcalfile_ files that were stored on the D:/Calfiles directory will be restored automatically. Other files must be moved or copied manually.
--- End quote ---

If there are more located in the other directory, please include these as well.  If they are the same name, maybe just rename them and let me know where they were stored.   Could you also provide the Application Code Version you are running.  This can be found on the About page.

Joe, zipped file is attached. Filename includes the code version. Folders in the archive indicate location. Cheers.

Thanks, I have them now.   

All pure guess work and just talking out of my ass,  looking at the raw data, it appears they have everything in 8-Byte records.  Records end in 3f-42 & 0 (I'll call that the record type).

FORZ12vs21:   Looking at your two files, index 2 & 3 are swapped.  Much of the data between these two files are identical.  Perhaps some sort of very long pointless header.   

FORZ_JQS_12vs12:  Your 12 file compared with the one I generated.    Index 0 and 4 do not match.  Perhaps an encoded serial number?   Then there is again a very long header which appears identical.   

Forz_12vs21_data:  Looking at your two files, everything is identical starting at index 4 to 95.  I suspect after this is the actual data for the receivers.

Forz_12vs21_data_flip_decimate_combine_fixpoint:
I suspect one file contains data for two receivers?  If I strip off the record type, then flip the byte order, decimate the records and convert it to some sort of fixed point we get this mess.  One column per receiver, 182 records each.   Guessing they would do a linear sweep from the 300k to 9GHz.

I'll try loading your files onto my PNA and see if it barks about a SN.  If so, then change those two index's and see what happens.  If it loads, I expect there is going to be a fairly dramatic change in the offset.   If it seems right, maybe introduce a disturbance in one receiver.   May not be too bad.  Then again, as I said, all a guess.
