Good Morning All,
This will come from
the department of odd questions (that is, supporting really old stuff), but
here goes:
I'm a retired Vet
(USAF) with Tektronix experience that goes back to the 465M 'scope of the
mid-70's. I'm working with a recently separated Vet, in getting him into the
'cable' business and was planning on donating some of my gear (i.e. Tek 1502
TDR, s/n R118430) to start him out up. When I pulled the unit out of the
closet, I could not get the 4 division high pulse (Manual 170-1792-02, 4-2 and
4-3,) that I did when I last checked the unit. This is what (all) I see, with
or without the 50 ohm terminator in place; also very noisy:
So, is my tunnel
diode or the sampling network shot, or, as I suspect has my shorting BNC
connector gone?? Or.....
These are what I
used to get reading a cable:
My question becomes,
any "old-timers" around that might be able to start me on the path
to fixing this up?? I've thought about sending it in for a calibration, but at
the moment the dollars just are not there. I'm an M.E. not an E.E!!
Any suggestions or
contacts would be most appreciated.
Respectfully submitted,
GLB
