Tek AWG2041 how to generate short waveforms?

<< < (3/3)

coppercone2:
Do you guys know where I can find a schematic of the CRT driver/power supply of that thing with the capacitor values? (not the main PSU)

I desoldered some bad caps in mine but I have no idea what I am supposed to put back, the project got interrupted. They all have the same one.

PepaZdepa:
Do you mean this  ;)?

coppercone2:
yes that.

I would personally recommend you replace all those caps. All of mine were leaky. I can't read the values that good from your picture though.

Symptom of leaky caps = screen fucking off every once in a while, getting dim, etc. Mine also smelled like cat piss.

I will tell you which values I need if you want to help me. Unfortunatly my PCB is different.

Maybe the values are the same. I need C302, C217 and C319. They are all near the fly-back transformer. I think it cooked them.

If you watch Mr.Carlsons l;ab though, he takes apart similar equipment (but I think it was a scope with the same PSU), and all the caps are bad in it too.

PepaZdepa:
OK, my CRT module is Toshiba D7MM-01
The caps are (from left to right):
C423 - 10uF/250V
C416 - 100uF/50V
C415 - 470uF/16V
But I'm afraid, your module is completely different...

I normally use the sequencer so the minimum is 640 points.   I tried this out and indeed, below 640 I the ARB throws an error.   This limit may be found under the Memory Control.   According to the manual, even if you do not use the sequencer, you are still limited to the multiple of 32.

My AWG2041 is on FV 1.70.  Does anyone know how to update it, or dump the firmware in an existing machine?
