Hi, I am looking for a manual for a Tektronix 1L20 Spectrum Analyzer plug-in. I believe it is used with the 555 Scope? Regards, Andrew

Rich, the 465, 465B, 475, 475A, 464, 466 and 468 had identical fan modules. And by the way, this has nothing to do with bearing noise, but if you have a fan that has a dead spot and won't always

I recently picked up a 475 that has intermittent horizontal jitter and a noisy fan. Does anyone have any ideas about the jitter? The fan looks like it could be a challenge to replace. I am shopping

Hey, its perfectly OK to disagree with me, but in this case, you are also disagreeing with Tektronix since it is in the Tek microfiche where I read about the power supply problem. Yes, I suspect Tek

Hi, Would the person that responded back to my message concerning the communication options for the TEK 2230 please respond again. I can't seem to find your message. Thank

I hate to disagree with Stan, but my experience with 7A16Ps is that if you install them in a non-programmable mainframe, they power up OK, but the front panel is locked out. From looking at the

Thanks all, for your replies to my question... Kind regards, :) Michael

I have the start of a Tek interest site : www.vaxxine.com/phil/ Phil Turcotte Grimsby, Ont.

I would ask again that anyone who wishes to can place a URL link to their site in the LINKS section of the TekScopes Yahoo site. Also, people who have parts etc to sell, but DON'T have a web site,

Hi Bob, There is some possible incompatibility using the 7A16P in a normal 7K mainframe such as the 7704A. The 7A16P was specifically made to be used with the 7912AD digitizer and is programmable

As I recall, the reason Tek would not recommend a 7B53 as a timebase for a 7704 is that it will not sweep fast enough to take full advantage of the 7704's 200 MHz bandpass. Other than that, I believe

Hi all, :) A couple of times recently there have been mentions of people who hold some stocks of Tek parts for sale for replacements. (e.g. pots, transistors, tubes etc). After a recent rebuild

Hi All, I am looking for two (2) Tektronix 475 Position Pots. Tektronix Part Number 311-1411-00. Regards, Andrew Campbell Calibration and Repair Network Pty. Limited A.B.N 64 090 761 363 An

Yes, that's what I was talking about... I know it's written up in one of the manuals or catalogs, but I can't seem to locate it at the moment. I guess I'm just picky :-) On the other hand, 7B8xs are

bandwidth 7B53A's And Seconded - before I acquired 7B87, later -92As via a package deal: a 7B53 in my 7854 (400 MHz nom) scope worked fine. At fastest sweeps, with a known ~700 pS risetime pulse

The pot/switch for the CAL/VAR volts on Ch1 of my 2230 is disfunctional and there is no detent. Manual says 311-2218-00 Tek part number, but it describes it as an Allen bradley 10K pot with

There's not a darned thing wrong with using a 7B53A in a 7704 or 7704A. It's the 7B92/A that you can't easily use on lower bandwidth scopes only because they can't handle the faster sweeps. And

The 7B53/7B53A is not recommended for use in the 7704/7704A. I don't remember why, but I think it was a good reason. The original poster needs to find a 7B70+7B71, 7B80+7B85, or 7B92/7B92A.
