Hi Craig: The 1502 and 1503 Metallic Cable Testers (not the "B" and "C" versions) use a tunnel diode as a pulse generator and another for jitter reduction. Schematic ref CR1609 is the jitter

Thanks Andr??? The list is filling up - so far 18 different TD's, and I've found specificiations for 15 of those. The unit that has the most unique ones is the 1S2, and they are for the 50ps

Hi all, I am considering acquiring a 577/D1 curve tracer with a 177 fixture that was "rejected" by a cal lab. Studying the specs, it seems much more versatile than the 71CTN that I was previously

hi Craig, I've found a selected TD3A 4.7ma Tunnel diode in the 3T4 programmable sampling sweep plug-in unit. Anyway, it seems to be TD's in 3B3, 3B1 and 3B4 time base. for the 3B3 : 152-081 is TD2

Hi all Just because I'm curious, I'm trying to put together a list of the tunnel and sampling diodes that Tek used in what instrument, and as far as possible what their specifications are. I'm

Hi all, Does anyone know of a source for replacement front plastic panels for the single bay plug ins? I'm sure you have seen em with the bronken or cracked corners. Thanks ahead! Chris

http://www.bitsavers.org/pdf/wavetek/ Looks like scans of the 110, 132, 145, 154, and the glorious 166 function generator docs. Pop up a directory if you have any interest in historic

I am getting the insane info that #7329 is the last post on this group, and I don't know whom to contact about this. Any ideas will be mightily appreciated! Thanks in advance, Jonathan

Darrin, I find a lot of bad power cords in the older scopes (453s) due to age and maybe some abuse - pulling plug out by the cord, sharp bends, etc. Use an ohm meter to check continuity of the

Hi Peter The DSA circuits were never published (like 99% of the TDS scopes and most products built in the last 10 years.) The failure is in the mainframe (plug in none - means no failures for the plug

I have been testing my DSA 602 ( 6 of 12 channels, 4 x 400 Mhz, 2 x 1 Ghz ) with Option C04 ( > 1 MBy total non volatile RAM ) for a few days now. This beast is really the most stunning scope I ever

Grettings All! I have a 465M that just cannot decide whether it wants to be on or off. It powers up fine (with a crispy trace!), then the power LED blinks with no kind of timing at all. As this is

Tektronics CRT V300 Pn: 154-0642-00 Any suggestions with testing the CRT? The problem that I can see is a circuit by the name of the " Grid Bias Circuit". It supplies the voltage to the CRT grid

Is there someone here that can help me with a 7L12 that has suddenly lost sensitivity by about 50 dB? The problem seemed erratic at first. A couple times when I first turned it on it worked OKat
