Hello Ed,
Here is what I have on TU-5, a data sheet that I got on this list. I have a
hulk of a TU-5 and it does have BNC connectors; perhaps in earlier version
this unit had UHF connectors.
Be careful when connecting the unit to the signal source. What looked
intuitive connector polarity to me, is actually wrong and I connected 10 V
pulses directly to tunnel diode, so now I have a hulk of a TU-5.
Regards
Miroslav Pokorni

Subject: [TekScopes] Tek tunnel diode pulser
Hi, Gang
I picked up a Tek 067-0554-00 tunnel diode pulser.
(There's one for sale on eBay now, it you'd like
to see a photo).
It is a little box that goes between a 100 volt square wave
generator and the scope's vertical input, to test the risetime.
The effect of the tunnel diode is to "sharpen" the edge
of the square wave.
Does anyone have the specs for this unit?
I'd like to know the specified risetime of the tunnel
diode pulser output and the type of tunnel diode used.
There are only a few parts in the box, and should be easy to home-brew.
I think a Tek TU-5 tunnel diode pulser is the same thing,
except it uses UHF type connectors instead of BNC.
The manual for the 1A1 (Nuvistor input) plug-in, page 6-9
shows a TU-5 in use to check risetime.
Thanks,
Ed Knobloch
