You can set the overall PLL divider to any even value between 4 and 66
as there is a fixed /2 prescaler preceding the programmable divider, so
with a 20MHz reference (from a 10MHz source) set the overall divider to
50 to give 1GHz - not sure if you set N to 50 or 25 in the Eval.
Hi John,
This is an old analogue design, but have used and sold them in the past. A
bit of a bugger to set up, but they work well.
Good luck!

Some more testing today. It turns out that AD's schematic for the
evaluation board doesn't match with reality - and so I had not connected
the PLL filter components at all previously! Now they are 'in the loop' and
I get reasonable results without the 2x reference clock setting. With 2x

Several observations:
The listing is titled and the item is described in the listing text as

The frequency standard arrived today. It is indeed an SLCR-101.

Could the remaining -60 dBc spurs at +/- 50 kHz be due to my 10MHz clock

Yes the spurs could be from your source. that's a function generator/ARB

Just for reference, my LPRO-101 is dirty as dickens. I get solid harmonics out
to 150MHz. I haven't looked at it on a scope yet. There's a good filter on
line, I think it was made for the LPRO, if you want the link, I'll look it up.

As promised here is a list of all the HP 5065A
units I have come across.
I believe there should be a 08xx prefix out there
as the units first came out in the middle of 1968.
I also think that the 2816A prefix is the last
prefix used.
Anyone have any others I can add to the list?
Another tidbit,

Hi John,
I have original Austron manuals, including 2010 and 2110. And working units,

Hi Corby,
Thanks much for your effort to accumulate all this history, as well as

I have a manual for the 2110 at work, including several fold-out schematics as

It looks like I will play around with the evaluation board some more, and
see if I can get the on-chip PLL to behave better.
The settings with 2x edge-detector and 60x PLL were the only ones I could

Driving the DDS system clock from an expensive RF generator (e.g. HP
8648A)
would be possible but I'd prefer a PLL from 10MHz if it's doable
simply/cheaply.
Although expensive from a hobbyist viewpoint, the HP8648A is
far from HP/Agilent's best,
Actually the Rohde SMA100A with opt B22 is pretty darn good, and Rick is being
a bit humble, the Agilent E8663D is also very good.
I hope all member have a happy and prosperous new year.
