hi Robert,
I seem to remember that a while ago you reverse engineered a (I think) Tekprobe interface for a probe you bought but I fail to find the thread.
Do you remember where and when it was and any keyword that would help? (or even better a pointer to :-)
I've got a P6207 probe with a level 2 tekprobe interface and the scope don't have that interface.
-- Thanks, Fred.
was it this one?

Unfortunately not. I did find that one and it's all about passive probes attenuation factor readout, but the one I remember had infos about active probes gain/offset compensation and serial bus readout that are included in some late tekprobe interface.
-- Thanks, Fred.

I think you were refering to my small "powerprobe" contribution, but it was for Agilent's probes unfortunately. For those who may be interested it was a small power circuit wich allowed me to use an Autoprobe compatible probe, like the HP1156A, without an Agilent scope. See there :
Friendly yours, Robert Lacoste

Perhaps look at the tektronix site then. I have created a hi-z probe for a dsa-600 which draws power from the scope itself. The available power is +/- 5v & 15v. The offset voltage is DC +/- 1v or 10v depending on the vertical scale. I believe the compensation is software. The readout is smbus. There is a tek made power box for these probes so they may be used on other equipment w/o probe power available. I'm returning to the salt mine tomorrow, so if you need more info I'll gladly check my notes and report back. regards, al

Well, that explains why I didn't find anything (was looking for "tek").
