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... |

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!" His youtube channel: |
