I'll guess. OK, then LSD displayed = 10 uv. Got one of them, too. Then anything involving that digit is suspect, which carries over to the next digit in what I'd say is a possible 1 digit error. I'd

Well yes - if you filter of course you are going to see a lower reading, as you will if you use weighting. The numbers I quoted were straight from the AA501 manual. But if you think that your

Close, but how about this scenario: I have a 5-1/2 dig DMM (dc) with 200mv low range. I have a voltage ref standard with 1uv resolution. I know the std is good in the 10uv slot but may be off in the

Think of the STM as being more like dragging a phonograph needle over the atoms in the surface of a material. The STM needle doesn't actually touch, but comes as close as possible to touching without

What about the many SMD electrolytics which are just radial electrolytics anchored in a base with their leads bent over and cut really short? Dave Casey

Not to put too fine a point on my nitpicking, but AFAIK, the capacitor plague applied only to radial leaded, low ESR electrolytic capacitors, not to SMD electrolytic capacitors. The problem mostly

Hello-- Apropos of an earlier discussion, I came across the following web page: http://www.opencircuits.com/Atomic_microscope Very interesting, and no need for a high vacuum(?). 73-- Brad

I don't think so. By subterfuge I can get it to measure .0008%, at 100kHz with tiltering, as the AA501 only goes up to 300kHz. Dennis' statement is further evidence. But I am going to revisit the

This is the case for the Royal McBee LGP-30, and several examples still exist and operate. https://www.youtube.com/watch?v=7WaYYNUCWMY - scope at e.g. 3:12 --Toby

Hi Michael, Don't do anything until you read this article which explains the problem in detail: https://en.wikipedia.org/wiki/Capacitor_plague Dennis Tillman W7PF

Hello Peter, My first scope was not a Tek (it was a Kenwood of the 80s) and, like some Teks, it has a feature that is known by the name "Auto-Focus". The Kenwood had a problem that was exactly as what

The HP 1600/1601 logic analyzer would do much the same. Not sure about the Tek 308. (much later vintage). Most of the early hardware was considered unreliable enough that there was considerable

Would an RM504 do?  I've got one I've been saving to send to a good home. My understanding is that some of the very first *digital* computers also had scopes on them.  I cannot now find the

Hi John, To achieve greater density on a floppy manufacturers had to make the tracks much narrower. To make the tracks narrower required more precise read/write heads, more precise and more

The problem will never really be completely solved, as long as manufacture involves putting a plastic/rubber sealed, liquid filled, component into an oven heated to soldering temperatures as a means

I am not certain of your question, but I think you are asking how good does a cal lab need to be to calibrate a scope. Generally, tek scopes run out of accuracy somewhere worse than +/-1%. A good

I know, I got your gently pointed hint. I often tag onto someone else's reply post to further elucidate (hopefully not obfuscate?) their useful response. Anyone that gets at all serious with

Chuck, At what point would you say that the intermediate cal was good enough for the work at task? Sent from kjo iPhone

In my kit, l supply 440VAC film caps for the replacements, instead of the stingy original 275VAC paper caps, so that will offer more than ample margin to any 24x5 owner, no matter where in the world
