Re: TEK 485

The underspend thing, which I first came across when the professor of microbiology explained it to us in the 70s, always intrigued me. No way could you fold the underspend into next year's budget. Underspend was a crime. A year back I bumped into an accountant I worked with 40 years back and asked h...

Re: TEK 485

It was under the part about the Triax cap on the Farnell link you gave. Associated Poducts. I'm sure it gave two which were £19 grand and over £20 grand. I've just looked and they offer two at £16 grand and £19 grand. I didn't have my computer specs so maybe they were USD prices or they may have bee...

Re: TEK 485

I suppose so, but if you are in the world of £20,000 femtoammeters, everything is going to be expensive, including things like carrying cases. Most buyers will not be spending their own money anyway. I thought Aliexpress might be worth a look for something like that. There are not many triax items o...

Re: TEK 485

Triax is something most of us don't come across, and to produce it is going to be taking a risk. There were one or two odd BNC types. What's the difference between a 10dB attenuator you've put together faithfully following the equations in the book, and a for real 10dB 20W attenuator good from DC to...

Re: TEK 485

I had to think about why I ended up looking at my terminations, then I remembered. A while ago, I bought a Leo Bodnar GPS disciplined oscillator. It produces 10MHz and 96kHz. When I plugged the 10MHz as external reference to my 'scope, it didn't like it. It turns out that the Ref. In on a Tek MSO54...

Re: TEK 485

The 50 ohm terminations on my 'scopes are better than my feedthrough terminators, but (oddly) I get better results with a T-piece and term than the feedthrough. My feedthrough terms must not be very good. Checking quickly with a 1MHz sine 500mV ptp from the internal AWG in my scope, I find the scop...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

The widespread ownership of cars made a difference. In the village where I grew up there were five shops in the late 50s. There was a post office, a butcher, a general sweetshop/birthday card shop, a grocer and a newspaper shop/cafe. There were three pubs. By the 70s there was the grocer, the sweets...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

This is largely true. Supermarkets cream off a lot of trade in basic items, smaller sellers would have had as bread and butter. Garden stuff, tools, kitchenware, making it harder for independent shops to exist. There are very few butchers and fishmongers these days. Some types of shops pass in and o...

Three phase residential supplies are rare in the UK. Blocks of flats may have 3 phase. Industrial sites will have it. I've come across a couple of more or less normal houses with 3 phase.

Changing the subject, I thought I'd indulge in some pre-Christmas quality control this evening. We bought some 15yr Glenmorangie last week. First off, the bottle was fitted with a huge child-proof knob the size of a coffee cup over its neck. I had to resort to a hacksaw to cut the thing away. Sadly...
