[SI-LIST] FET Probe


Gurus,

Does anyone have a basic schematic for Tektronix FET probe?  I don't need
proprietary details about the probes, but just a basic schematic of what we
see looking into the probe, and relative to scope ground.

The reason that I am asking is that I have a board that will not come up
properly when the positive terminal of the probe is hung off of a DDR strobe
line.  No ground attachment required.  With the probe disconnected from the
scope at the scope, the problem does not exist.  Anyone seen this before?

Thanks in advance,
