Hello!
I have a problem with PCS500 calibration:
CH1 Trigger low
CH1 Trigger middle
CH1 Trigger high
CH2 Trigger low
CH2 Trigger middle
CH2 Trigger high
EXT Trigger middle
- all these fields have failed at calibration in a new (1 month old, PPCS500-9 PCB Rev.) PCS500.
I have old revision of PCS-500 too, but iI have no these problems with it.
I working with old revision of PCS500 more than 4 years, and i have no problems with it all this time.
Trigger failure on new PCS-500 is widely discussed problem on this forum.
I think, that it’s a well known problem for PCS-500 designers too.
What is a difference between new & old PCB revisions of PCS500?
Is it a problem with IC32 (NE5210), or with another components?
Unfortunately, I can’t send PCS-500 to Velleman because of my current location.
What can I do (as an electronic engineer) to repair PCS500?
Thank You.
