Advantest R3273 / R3267 Repair
chick0n:
I repaired a R3273 Tracking-Generator module. The MC12093 Prescaler Chip on underside of PLL Board was broken.
Maybe its helpful to someone.
Davide_M:
Hello!
I have an Advantest R3267 with options 01, 01, 08, 62 and in 3GPP mode fails the “DC CAL” and “Gain Cal” tests.
In both tests the message appears “Error 703 - Modulation DC CAL error” (see attached image).
Unfortunately I searched in the service manual and in the various forums but but I haven't found any indications that can help me understand the cause (I assume it's the Synthesizer block is fault).
All other tests and calibration it passes successfully.
Could you help me? Any ideas?
Thanks!

Hi Davide, and Happy New Year!
All the 6x (61, 62, and so an) options needs the DSP module, which is option 01. The error 703 which appears on your R3273 is related to the calibration routines of the DSP module. To proceed with this calibration, the CAL signal must be disconnected from the RF input, as the message indicates “Remove input signals and try again”. Hopefully this time the calibration routines will pass.
Best regards,
Gyorgy

Good day!
Happy New Year!
This winter, closer to spring, we will do preventive maintenance ADVANTEST R3273.
I think there will be an opportunity to look at the Tracking-Generator module.
What questions did you have about it?
Write.
With respect 3G57.
R32,R40?
chick0n:
yes..position of R32,R40
A Picture of the Underside of your Tracking Module, would be nice.
