Re: [time-nuts] A Prologix GPIB-USB hint

Poul, This has been fixed in the most recent release. Abdul added a ++read command that gets a single reading and then turns TALK off the instrument. I have not actually tried it, but I have received it from Abdul a week or 2 ago. The firmware isd easy to upgrade. Give him a call. Didier

Re: [time-nuts] Galileo funding (bailout)

So true, so true. It's funny seeing some GOES receivers antennas still being listed on eBay for hundreds of dollars when they have no signal to receive. Something I've always wondered about the ACTS system, is there any public code so that a person could run their own local ACTS server? I

Re: [time-nuts] another Ebay mixup

Don't know why it's so difficult for folks to overpack. Worst case, one can have it professionally packed at MailBoxes etc. or the like. What's their batting average? Do they recognize heavy instruments and/or do anything special when they see handles? -- These are my opinions, not

Re: [time-nuts] another Ebay mixup

The answer is simple ... Packing = $$$, right off the bottom line. Since most, if not all electronics on e-Pay is sold as-is, the seller has no reason to be concerned with the item arriving safely. Only his conscience, which, sadly, in the case of most sellers is non-existent. Don't blame the

[time-nuts] ATT /Lucent 10 Mhz reference Oscillator F/S

I have a ATT /Lucent 10 Mhz reference Oscillator F/S Part number ED2R849-31 G4 I can send pics if interested. I got this a long time a go and it has been in my garage for a while. Now that I got my Trimble working I don't think I'll ever do anything with it. So I'm offering it up here.

Re: [time-nuts] another Ebay mixup, 5370

Hi Bruce, and finally here is a plot of both the 5370B and the Fury 10MHz sine wave spectras for comparison. It only takes a 5 - 9th order passive lowpass filter to make a nice sine wave out of the 5370B output, I wonder why HP didn't do that back then. Also, I think the 10811 output

Re: [time-nuts] another Ebay mixup, 5370

One of my 5370A's had a severely distorted sine out, which Bruce helped me trace to a bad solder joint on one of the cap that is part of the output filter. After reflowing the solder joint, it all came to life with a pretty good sinewave output. Some of the caps on the amplifier board look

I am definitely not qualified to calibrate them for money. I will generally take a look at peoples' gear for free as long as they understand that they're lucky if it works as well when it leaves my bench as it did when they brought it over. :) -- john, KE5FX Wow, 10ps RMS is nice. I would be

Re: [time-nuts] another Ebay mixup, 5370

Pretty similar results here, taken from the 5370B's rear-panel output while running on the internal 10811B (attached). Indicated jitter with this setup is about the same as it was on the ext ref via the 5087A (10-12 ps). I've seen this counter return self-test jitter results in the 15-25 ps

Said, You sent pictures of the Fury's waveform, only the spectrum of the 5370. I did not look at the spectrum at the time, bu the waveform on the scope was low in amplitude and looked like 30 MHz with some 10 MHz component. It turns out a cap in the output filter was not making contact, and

I have had two really bad packing jobs come to me, with serious damage, and in both cases, the vendor made it right. A DC-503 counter and TM-501 mainframe came with the front panel busted (but still working) and the seller gave me full credit. In another case (not quite as much damage on an HP

The unit is actually relatively young (1990's), and has virtually no dust whatsoever in it. Seems to have had very low usage. The actual 10MHz is pretty accurate, to within 10mHz. Has anyone else measured the 5370B output jitter? bye, Said Oh so many projects, so little time. I
