Yah okay where is it.....
You are giving me TEPA (Test Equipment Porn Anxiety)
LOL
Here you go , its a Tektronix A6902A Isolator.
Its in pristine condition complete with all probes and it's accessories. The completeness of the probes + accessories is the primary decision to buy it, as they are not normal ordinary scope's probe.
It has two types, a lower voltage ones capable of 500V and HV ones rated at 1500V, both came in pairs.
Hell, even the 2 BNC 50 Ohm patch cables are still the original Tektronix made cables, and the original manual is also included.
Quite surprising its still very new, even all probe's tips and hooks don't have nicks or scratches at all
, looks like the previous owner never or rarely used it ?
All probes still have the retractable hooks, the common clips and the sharp tip covers.
One thing for sure, its huge and heavy 6.2 Kg (13.7 lb), attached photo below for size comparison with popular desktop scope. You can see that the whole probe system is bigger and heavier than scope it self.
Hopefully I have time to post the teardown soon in this forum.
