Re: [time-nuts] HP Z3801A and Tac32

Hi There are a *lot* of places that archive this list. As long as you know roughly when the messages came through, it's not to hard to go dig them up. That's also a good reason to keep things on list rather than taking everything off list. Bob On Nov 12, 2012, at 8:53 PM, Merv Thomas

...When you switch on the SR620 the fan should be slowly increasing its speed over several minutes if the circuit is operating properly. That's what my fan does (over abot 15min), but it doesn't stop increasing until it's reached maximum speed. If you bought your SR620 second hand of

[time-nuts] TADD-2 Mini Sine or Square signal input?

Dear Group, Does anybody know is the TAPR TADD-2 Mini works with input signals with square wave geometry? Or Sine wave only? Thank you. Regards, Edgardo Molina Dirección IPTEL www.iptel.net.mx T : 55 55 55202444 M : 04455 10045822 Piensa en Bits SA de CV Información anexa:

A 50% duty cycle square wave with an amplitude 5V pp should be OK. Bruce Edgardo Molina wrote: Dear Group, Does anybody know is the TAPR TADD-2 Mini works with input signals with square wave geometry? Or Sine wave only? Thank you. Regards, Edgardo Molina Dirección IPTEL

[time-nuts] Can a VNA be a high resolution frequency counter

I have been looking at the DG8SAQ VNA for other purposes and it is suggested in the VNWA_Help.pdf on page 158 that it can be used as a high accuracy / resolution counter. Document available at http://www.sdr-kits.net/vnwasoftware/?20. Ignoring any drift in the TXCO as I would drive it

Was that aimed at me Bob ? The article I pointed him to off the list was wrote by me years ago - when Time-Nuts was in its infancy - in fact I found Time-Nuts via that list (Bill Jones sent me to Tom Van Baak). I do not believe in duplicating the effort and there were pictures there about

Re: [time-nuts] TADD-2 Mini Sine or Square signal input?

Hello Edgardo -- The T2-Mini uses a wide-range input circuit based on one that Wenzel published with some modifications. It works with a square wave input (I've done some limited testing) but I can't verify whether the input amplitude range will extend as far on either the low or the high

Hi No, not at all, my only point is that keeping info on the list is a good idea for many reasons (like deleting emails by accident). Bob On Nov 13, 2012, at 9:04 PM, Brian Kirby bryan-ke...@att.net wrote: Was that aimed at me Bob ? The article I pointed him to off the list was wrote by

Re: [time-nuts] Can a VNA be a high resolution frequency counter

Hi The help file is correct, but possibly a bit misleading. Most of what they show could be done by a computing counter. They have been around long enough that they are a sub $100 ($50?) item these days. Clock jitter is going to be a very real limit doing what they are trying to do. Bpb On

Re: [time-nuts] TADD-2 Mini Sine or Square signal input?

Dear John, Your response is welcome. My square signal input is 3.3V and 50% duty cycle. Low end 0.5V, High end 2.7V. Will I be able to make it without the bypass? Or should I start warming the soldering station? Thanks! Edgardo Molina Dirección IPTEL www.iptel.net.mx T : 55 55 55202444

Re: [time-nuts] TADD-2 Mini Sine or Square signal input?

That should be OK connected directly to the input as the resultant reverse bias on the switching transistor base-emitter junctions is well within the specified limits One can check this both by simulating the performance and by actual measurement with a scope. Bruce Edgardo Molina wrote:
