| Cloning the HP3325A Option 002 - HV Output |
| << < (6/18) > >> |
| TERRA Operative:
Ok, time for some small updates. I recently ordered a bunch of PCB's, so they should arrive soon. I also just won another 3325A on Yahoo Auctions, with opt 001 (ovenised oscillator) and 002 so I can more easily compare performance between an original board and mine. Updates to come soonish. :) |
| SilverSolder:
Building @Jay_Diddy_B's improved board could also be interesting! |
| TERRA Operative:
Yeah, I'll have to get my hands on one when they are done to do a 3-way comparison. Would be awesome if his could be used beyond the 1Mhz limit of the HP one, but I'm not sure if that'll require reflashing of the ROM on the 3325A motherboard or not? |
| LazyJack:
It should not require a new ROM. My 3325B is happy to provide any frequency, even is Opt002 is enabled. It seems like that the only change is that id adjusts the output amplitude display, but does not limit the upper frequency. |
| TERRA Operative:
Alrighty, I got my hands on an original option 002 board. ;D Here are some high quality photos of the thing for those who are interested. Interestingly, there was a shield on this one which I didn't realise was part of the upgrade. It wouldn't be very difficult to make one at all. |
