This is a very common problem... basically the fan blows directly down the chassis onto the front panel area where a large dust bunny builds its nest. The switches are gold plated leaf springs that slide on a gold plated circuit board. They are open to the environment and collect all sort of

I just finished an LED clock kit that can be found on hackaday.io by Nick Sayer. Below is a link to a couple of one take videos I made of the clock. It's a nice piece of eye candy. I haven't see an LED clock kit like this that uses a lite

Yes, they are both set to "positive". Leaving the start at "pos" and switching the stop to "neg" gives 66 ns. One more observation, which probably does make sense: If I set the ARming to +/-TI and toggle the Period Complement the "sum" is always very close to 100ns: 15 is complemented by -85 and

I got hold of a 5370B cheaply but it turns out it may have a fault: Going through the motions of measuring TI with it's own 10MHz ref as input (as described in the manual) I don't get 100 ns, but around 15 ns. So this is with the switch set to START COM. Oddly enough I get the same 15 ns with the
