From: Dave Carlson [EMAIL PROTECTED] Subject: Re: [time-nuts] Symmetricom 5071A Date: Sun, 26 Jun 2005 19:56:36 -0700 Message-ID: [EMAIL PROTECTED] Hello Magnus, Hi Dave, Your question: Or, to put it in another form, do you know where the HP/Agilent tubes are actually made (I.he. not the total clock assembly)? Since the early 1970s made in Santa Clara CA, corner of Stevens Creek Blvd and Lawrence Expressway, at the site once owned by HP and later by Agilent. Before that they were made by HP in Palo Alto, Ca. Never has Symmetricom or any other CBT manufacturer made CBTs for HP or Agilent. HP/Agilent always made their own. Other CBT manufacturers have made a CBT that could be retrofitted into a 5061A/B Cesium Beam Frequency Standard, but not the 5071a. OK. Great. Thanks for the effort. I will talk to my friend today and ask what he has to say about it. He was probably missinformed, but he sounded quite certain. He probably missed out on that detail.

RE: [time-nuts] Symmetricom 5071A
Never has Symmetricom or any other CBT manufacturer made CBTs for HP or Agilent. HP/Agilent always made their own. I thought the CBT's were originally made by Varian for HP. That's why the CBT burn in fixtures (still in use today AFAIK) are marked Varian Associates. In any event, the 5071 CBTs have never been outsourced.

Please tell me where you got that. I'll check with my source. He pointed out this fact to me last year. Naturally, I could have got him wrong, or he could have his facts wrong. The HP/Agilent 10890A and 10891A CBTs could not be legally re-engineered and the 5071A chassis required that the CBT installed be only one from HP/Agilent. You interprent what I said as it is the same tube, I did not say that. What my source said was that they where manufactured by Symmetricom. Or, to put it in another form, do you know where the HP/Agilent tubes are actually made (i.e. not the total clock assembly)?
