[time-nuts] VIGO time interval devices
Jose Camara-Berkeley Nucleonics has them, Keithley has them, they all must come from the same Chinese OEM. Maybe the quality is good, maybe the specs are honest and apples to apples. Or maybe not. --- Interesting to note that the Picotest/Array U6200A and the BNC 1105 use exactly the same photos in their ads. The major difference seems to be the asking price. http://www.picotest.com.tw/product02.html http://www.array.sh/yq-u6200ae.htm http://www.berkeleynucleonics.com/products/model_1105.html ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
Re: [time-nuts] VIGO time interval devices
A couple more :) http://www.acquitek.com/u6200a/counter-test-measurement.html http://www.ptsyst.com/U6200A-B.pdf (even with 20GHz input option) Similar thing I found some time ago when looking for an electronic load. Same thing with several different branding, price ranging for 1 to 2.

Re: [time-nuts] VIGO time interval devices
If anyone was ever to review such a device the actual power consumption would be usefull to know. The likely savings in electricty costs could provide some justification for replacing one of my HP5370B's (: Devices that could also easily run from a DC power source could have merit as well. --- On Tue, 11/1/11, Jose Camara camar...@quantacorp.com wrote: From: Jose Camara camar...@quantacorp.com Subject: Re: [time-nuts] VIGO time interval devices To: 'Arthur Dent' golgarfrinc...@yahoo.com, 'Discussion of precise time and frequency measurement' time-nuts@febo.com Received: Tuesday, November 1, 2011, 11:50 PM There seems to be a deluge of these OEM counters, mimicking the 53132 operation, with a bit better specs and built-in 3rd channel.

Re: [time-nuts] VIGO time interval devices
What about the Racal Instruments (Racal Dana) 2351 8pS, 300MHz? Yes, it is VXI but 8pS one-shot seems interesting...

The specs for the Racal 2351 indicate it might take 16.6 minutes to attain 8ps resolution, if I understand the specs correctly. Check under resolution mode vs max. sample rate, meas. time under input characteristics on the spec sheet. http://www.testequipmentconnection.com/tecspecs/Racal_Instruments_2351.PDF -Arthur ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Nutters: I've been emailing with the VIGO factory about the T3200U counter/timers. The specs looked good. Here is the factory reply: Hello, We will open a Pay Pal account if needed. Following please find the requested quotation: QUOTE #1xxx T3200U...2270,_ USD Prices are EXW VIGO System (do not include cost of shipment insurance) Shipment within ~4 weeks ARO Since these time counters are assembled as orders come in, we offer them on the basis of prepayment: Upon receipt of the order we will issue a proforma invoice with all details needed to arrange the payment. So, there is probably not a user community out there, and my guess is the counters will be buggy. At that price, they will disappear from the catalog Real Soon Now. Recovery of engineering costs in the first few units ain't a good business plan? Needless to say, but I will anyway, I do not plan to order one of these in the near future. Will stick with my Hp5370A's and 5363B triggers, and Prologix net interface. (all of which is not yet implemented, so no, I do not have any handy hints yet :-)) But FYI, Don -- Neither the voice of authority nor the weight of reason and argument are as significant as experiment, for thence comes quiet to the mind.
