Actually I put a step towards the calibration proces allready, here are a few pics:
Basicly what I did is I used the empty spot on the A5 board that Tek probably reserved for some sort memory expansion, never used it anyway (at least I haven't heard of it ever bein used).
Unfortunatelly Textronix in their wisdom thought of only 16kbits memory here, 24pin chip like 6116 or such.
So I had to improvise a few mods using kynar wire, anyway the idea was to have a zif socket there, so I can make a simple patch cable using 2 28pin sockets to connect it to programmer.
I didn't feel at all comfortable pulling the eproms and nvram constantly during the "testing" phase.
The wear on the sockets an possibly the chip pins was a risk I did not like to take.
After I put the NVRAM chip I couldn't use the simple clip/cable (that was unreliable in the extreme anyway), I had to devise a way to read the RAM without pulling it everytime from the machined socket, risking a broken pin or such.
So we will see how it will work, I'm planning to do a quite a bit of memory reading during calibration procedure( at least once every step), we'll see how that goes.
As far as gear goes, so far I got his:
That does this:
That's a 50nS pulse, just look how sharp are the edges!, isn't that amazing.
500pS timebase :
As far as other stuff I may need I'm thinking of getting a new FY6800 or even older 6600 if it gets to be cheap enough.
May be enough to calibrate the scope.
PS MarkL , funny that you mentioned camping in Canada, the reason that I wont be doing the calibration anytime soon is this:
Bought this puppy before the winter and have to get it ready for the season, (lots of work), it's going to be the first season for me and my wife.
Cheers.
