I hope this goes thru ok and helps some people ... TDS Screen Capture via the RS-232 option This screen image was captured from a TDS oscilloscope over the RS-232 port using the Windows Hyperterminal

Hi All, I hve been a member of this list for some years now but not done much in the way of posting. I am having to part out a large number of scopes damaged about 10 years ago so I am asking advice

Greetings, ? Very good point. For high impedence gear, the ESR most likely is too low to be a factor. ? Jerry

This seller has a few expensive items, all of the bid up buy the same buyer. Seems suspicious to me. Neil

I've been watching auctions for 7D15s for a while because I have few I'd like to sell. The closing prices (not including shipping) have been around $10-$25, with some not selling for even less. Some

Absolutely - and can be retrofitted if necessary on a bit of bodge board. Craig

the Which is a -02 with only a minor mod. /H?kan

An -02 will work perfectly with any Tek scope up to 1GHz B/W. With the exception of the 7854, 7612 and 11xxx series with require -10. Craig

Like all these things, the devil is in the detail. Lets assume that we are talking about a smoothing capacitor conventional 50/60Hz system, and not a switcher. Provided the ESR is significantly less

Thanks all for the discussion. I have ordered new caps as well as an ESR meter. I expect the new caps will help, but am also curious as to the condition of the old ones. By the way, the comment about

I need a couple of spring hook tips for a P6109 probe. Does anyone have any to spare? David KC2JD/4

The 067-0587-02 (or -10) version is good far ANY 7000 series 'scope. The -10 version is also good for 113xx and 114xx 'scopes as well (I think). Dave

Hello, It's also dependent on frequency.. If the 'lytic cap in question is used in a good old fashioned line frequency copper/iron power transformer, the ESR requirement is not very high since ripple

Ok, I'm starting to understand a bit better. I'm in the processor of repairing the scope and have been trying to be careful to not turn pots that don't need it. But I'm getting to the point where the

Can anyone explain to me EXACTLY what a DM44 does? I assume it takes voltage measurements, but does it take it from the scope? It's own probes? Can anyone talk me into/out of getting a 465 with one

Primary use for a ESR meter for me is testing all caps in a circuit because frequently I purchase a piece of equipment which has been out of service for a LONG time and the electrolytics in many cases

The ESR is critical to ripple.

Ignacio, I believe that if you ask AA4DF, he will let you share the lower resolution scan of his manuals. I have bought the Tek 494P manual a year or 2 ago, and he let me post the low res version

Jordan, I found the origin of this manual. I bought it from AA4DF site . Since they carefully scanned and sell this hi quality manual (I paid $10 but I think now it is just $4.99), I think it is no
