David, Thanks! mark

Dennis, Thanks for that information. I think I downloaded the two documents you mentioned yesterday and started pawing through them. The one with the black screen shots I have for sure. ;-) I'll dig

David, Yes, thanks! Mark

(specifically the Dick Smith/Bob Parker model that Dennis was talking about.)

i do not agree, measuring ESR in circuit is only an indication, most ESR meters re only indicators who have problems measuring accurate under 10 uF because they do not measure the phase difference but

The cover for a 468 will fit a 465B/DM44. The cover for the 468 will fit a 465B without the DM option but it will stick way up in the front.

Hi again. Just mentioning one last time that I'm running a little contest on Scope Junction - the first 50 people to post an interesting, embarrassing, funny, weird, or otherwise memorable story about

You can use the metering circuit of a 7D13 to indicate any physical quantity or measurement that can be converted and scaled to a DC voltage that makes numeric sense. You can change the units by

Use an ohm meter to check each of the LV power supplies for a shorted capacitor. See page 2-8 in the service manual. The supply is trying to start up into a short circuit on one of the supply

The first couple of pictures showing the probe calibration square wave with some fuzz on it looks pretty normal if a source of HF noise is nearby. The width of the fuzz will change by moving the probe

I bought this R7903 at a local hamfest for $10. I'm going to try to see if I can fix it, mostly for the learning experience. I have had some minor experience working on electronics, but not on scopes.

The triangle was supposed to be a sine wave. I figure out what the problem is. It was the trigger! I posted new pictures. The traces are now thin and solid. The vertical is a little off, so I guess

Some things you ask about are easier than others. * The 7CT1N has no readout capability (hence the N suffix). It wouldn't be practical (or even possible) to add it unless you had the ability to make

To download trace information from a scope you need some way of digitizing the signal. That is why downloading of traces are usually only supported by digital scopes and not analog scopes. --Victor

As a guess anyone recognizing my name/posts would know I am making a hobby out of refurbishing/rebuilding a few 7000 series scopes and plug-ins. As I have been doing so I have become more and more

468 can't have a DM44, but the cover should fit just fine. -ls- Kevin Berlen <kberlen@...> wrote:

Oops, I realized that a couple of minutes after posting. You would have to use a negative resistor :)
