Re: [time-nuts] ZED-F9T

Hi So about three weeks later, Digikey shows no sign at all of ever having sold the F9T. it does not even pop up as “obsolete”. The F9P and the eval kit for the F9P are still up there in stock and chugging along ….. It’s a strange world out there …. Bob > On May 14, 2019, at 3:24 AM, Julien

Re: [time-nuts] Is there anyone local to me with an 8.5 digit multimeter?

Not that I'm an expert on this but, in the 10 Meg and 100 Meg ranges, I believe a variety of issues, including the triboelectric effect, humidity and surface contamination are going to be big factors, especially if you expect to maintain anything close to 8.5 digit accuracy.

Re: [time-nuts] Stable32 tau

Chris, If your data set is small enough (e.g., less than 40,000 points) so that all the tau are 4 digits or less then Stable32 will use plain integers in the little tau+sigma box inserted into the ADEV plot. For non-integer tau, or data sets that result in tau values 1 or greater,

Re: [time-nuts] Is there anyone local to me with an 8.5 digit multimeter?

You likely know this, but clean the resistors with alcohol before measuring.  Finger prints can cause significant errors, particularly on the higher value resistor.Regards, Tom Curlee.Sent via the Samsung GALAXY S®4, an AT 4G LTE smartphone Original message From: "Dr.

I have found my racks at the MIT flea in the past. The great thing about 2 posters is they easily come apart and can fit in the car. Plus the pieces by themselves are reasonable in weight. Regards Paul On Tue, Jun 11, 2019 at 2:05 PM Tom Knox wrote: > Hi All; > I have found when rack hunting it

Re: [time-nuts] Excellent equipment rack

Hi All; I have found when rack hunting it is best to look at local test equipment auctions. Even really nice racks often do not receive any bids and more importantly no shipping. In my labs I use exclusively Agilent/Keysight because they are exceptional quality and parts a commonly available.

[time-nuts] Is there anyone local to me with an 8.5 digit multimeter?

I'm located in Althorne, Essex (CM3 6DT). I'd like to get a couple of resistors (10 M and 100 M) measured on an 8.5 digit meter, then compare them to what a 34970A data acquisition unit says. I don't want to spend a fortune on very high-end resistors, so bringing the unit to a 3458A, and measuring

Re: [time-nuts] Stable32 tau

I've tried both Decade and Octave and it still denotes the tau values located in the upper right plot as scientific notation. I have seen other Stable32 plots from other users where the tau values were displayed as 1, 2, 4, 10, 20, 40, 100 and so on. I'm still looking through the options in

Re: [time-nuts] Excellent equipment rack

Very interesting!  Recently I had a somewhat similar experience.  My neighbor was throwing out some shelving that looked like what I need.  It was gray steel, all the vertical parts needed but no shelves.  I made shelves from plywood and ended up with a nice addition to my lab.  To make it

Have used older 2 post racks for years. Have 10 in service and like them. The older ones had been available cheap and are very sturdy/heavy. Like Perry I have done the wood base. Longer out the back then the depth of equipment for stability. If you do find older 2 post racks there are 2 types. The

Re: [time-nuts] Excellent equipment rack

In this case, “U” represents a “Rack Unit” or “RU”, which has been for some time the standard unit of height for rack-mountable equipment. One RU has a height of 1.75 inches. Pretty much all rack-mountable equipment of which I am aware have heights that are integer multiples of 1.75 inches.
