Re: 3336B Prom images

Re: 3336B Prom images
HI Jose, I'd say so, the A, B and C are just different on the outputs. The firmware is probably the same. All the boards I have seen have the PROMS soldered in, Hopefully yours are

Re: 141T zebra strip repair
Jack, I did it several times in the past. Only one wire (the one most separated from the others) carries about 6kV and must be replaced; remaining wires have voltages in the hundreds of V. I remove

One, and it's in there already, connecting the two boards. I suspect that's the internal trigger and acquisition signals from the sweep to the scope board. Unless I missed one, there are no jumpers
