Bob, The single-shot does not improve, it's 500 ps, but the averaging of N samples give you that result. The 53131 does similar tricks. Cheers, Magnus On 11/17/2015 02:27 AM, Bob Camp wrote: Hi At leas on the spec sheet I found, both counters have a single shot of 500 ps. The 6680 “improve

5371a is a TI analyzer The time pod itself is used for paying work so it's not available for time nuttery. Content by Scott Typos by Siri > On Nov 16, 2015, at 6:20 AM, Chris Caudle wrote: > >> On Mon, November 16, 2015 12:42 am, Scott McGrath wrote: >> More of a slip as I've noted I have

Hi At leas on the spec sheet I found, both counters have a single shot of 500 ps. The 6680 “improves” as the averaging goes up. http://isurplus.com.au/specifications/Philips%20PM6680%20Specifications.pdf Section 13-8 has a lot of “500 ps / sqrt(N)" in it. If N=1 (single shot) you get 500 ps.

Hi, PM6681's turn up at quite a good price too, and you get a lot of extras over the 6680 - does anyone know if Timelab will work with a 6681? Angus. On Sun, 15 Nov 2015 15:10:42 -0800, you wrote: >Thanks Bob > >I'm using the actual time pod for paying activities. This would be a counter >f

Why would you want to use a 150 ps 53131 instead of a counter/timer like the Agilent/Keysight 53230A that provides 20 ps resolution? The TimePod my have better noise specs but it is a really dedicated, specific-use device. Larry On 11/15/2015 10:42 PM, Scott McGrath wrote: More of a slip as

Thanks Bob I'm using the actual time pod for paying activities. This would be a counter for time nuttery using the time pod software. In those cases Where I don't want to fire up the 5071. I'm familiar with the Keysight counters and I have a lot of them into the high Ghz ranges The 53131

Hi I guess the first question would be - If you have a Time Pod, what do you need a counter for? Based on a guess that you need extended frequency range, either would do pretty well. My vote would go to the HP for a couple of reasons: 1) It’s more broadly supported in terms of driver software
