[time-nuts] Wavecrest DTS-2070C in the house
Hi fellow time-nuts! I am just happy to let you know that I am now proud owner of a Wavecrest DTS-2070C. I also have a SIA-3000P from before, which is nice for jitter but not as versatile as you would wish at all times. I think the DTS will be a nice complement. I was not suspect it to be that large thought, but ah well, life is full of supprises. It fired up and I have it doing some counting going down, but I think it is time to read the manual to figure some things out. Otherwise it seems fairly easy to operate. The LCD is BIG, so there is no chance missing the numbers even from some distance. Hmm. Time to make some shootout here... :) Cheers, Magnus ___ 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.
[time-nuts] Wavecrest DTS-2070C & 2075
); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY For anyone interested in acquiring one of these instruments. One DTS-2075 and two DTS-2070C units are available at very reasonable prices. These units are NOS & still have the original cal certificates packed with them. They may have been out of the box for re-cal, but have not been in service. These units do NOT include any S/W or accessories. If you're interested,please contact me directly for info. I don't own these units or have any financial interest in them, but I did buy one earlier from this seller & it works well. .

Re: [time-nuts] Wavecrest DTS-2070C
Hello Masamichi-san, yes, changing the 100MHz to be an input should be as simple as unplugging the SMA cable from the OCXO, unplugging the SMA cable from the rear panel 100MHz connector, and plugging the input cable to the unit to the rear panel connector. Of course this input is probably not ESD or overload protected since it was designed for an internal connection, so you would need to be carefull not to damage it, and to meet the power output of the Vectron OCXO etc. Also, the Vectron part has extremely low jitter (about 2.7ns on my unit), so your HP source needs to be as good as well to have the unit meet specs. I have seen the DTS instruments a couple of times a year on Ebay. Cheapest one was $400, someone wanted >$10K. One I bought was broken and service is very expensive or impossible, so make sure you have the seller do the internal and external calibration before you bid, and have him send you a picture of the LCD showing "Calibration done" (versus "Calibration Failed"). Doing the cal only takes about 5-10min, and is very easy to do since it is automated. bye, SJ ___ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
Re: [time-nuts] Wavecrest DTS-2070C
Dear Masamichi-san, thanks so much for the information. The DTS series uses an internal Vectron 100MHz OCXO with very low jitter specs (<3ps). This OCXO is connected with an SMA-to-SMA cable to the backplane PCB, so it would be very easy to feed an external 100MHz signal into the unit by drilling two holes, and adding an external feedthrough of the 100MHz signal... I bought one DTS-2050 on Ebay for <$1000, sometimes you can get really good deals. BTW: I have one spare Vectron 100MHz model 224-8647-1 oscillator from a DTS-2070C if anyone is in need of one. I called Wavecrest, and they want several 1000's of $$ for the GigaView software; all I am looking for is a way to get the time measurements into a text file to use i.e. Tom's Allan Deviation command line tools etc. I guess I will have to write a GPIB driver myself once I find some time :) Also, do you know what the serial port on the unit is used for? I can't find any info if it can be used to control the unit. Using the serial port I could save myself the money for a GPIB PCI card... Will check out the HP5372A's now.
