Advantest R3273 / R3267 Repair

<< < (11/13) > >>

In search for the DEBUG MENU Access, I extracted some undocumented GPIB Commands from the DFM file.
No Luck so far.

Maybe someone else wants to try.

Especially interesting ones:
$AR
$AW
$DDS
$EPR
$EPW
$FBFIX
$FCRD
$FR10
$FR5
$FSK
$FW10
$FW5
$R
$RAMP
$RF
$SR
$SW
$W
$WF
$YSWP

I think RAM / ROM Read and Write is possible. So be careful...

Hello Ginji!
Question: did you solve the problem with the signal level?

chick0n:
jjoonathan Uploaded a Calibration tool to Github. Maybe its helpful to someone:

"Hi! I went and uploaded my R3273 code here: https://github.com/jjoonathan/R3273-calibration . This should help with level correction, but I'm afraid I never figured out YIG correction due to the existing YIG calibration being quite satisfactory in contrast to the HP8565E in the video. I pointed out my best lead, though: there is a suspicious unknown "field5" in the cal data that might just hold the yig cal. Good luck!"
