Dear friends,
The first HP5065A were produced around the late years 60. Over time some flaws,
related to engineering and the choice of components, are highlighted.
The main ones are the following:
- The capacitors used primarily on power lines of +20 Volts tend to lose
the liquid inside
I thought I would pass this along, the auction site seller of the
LUCENT/SYMMETRICOM Z3810AS, KS24361 GPSDO's dropped the price by $25.00
The shipping is the same. Pretty amazing for shinny new old stock in the
original unopened box
No affiliation with the seller here, but I'm a happy buyer even

Hi list,
I've been lurking around for several years off and on, followed some
of the much discussed LUCENT/SYMMETRICOM Z3810AS, KS24361 L101/L102,
HP-KIO OEM GPSDO. As you know they have been on fleabay for more than
half a year are now, currently down to USD125 plus SH. Not bad for

The simple answer is that a biased fast CMOS gate will do a better job
ADEV wise than your signal sources will.
Maybe or maybe not, at tau ~1 second. Trouble is, as tau gets
larger, the gate performs *worse*. The switching threshold of all
MOSFET logic devices varies all over

there is a 20Mhz source onboard, issue is the sine is not very clean at 20MHz
