I only post this on the list because I know some here would be interested.
Covers 10 KHz to 1050 MHz, -127 to +13 dBm. Does AM and FM modulation
of 400 Hz or 1000 Hz. Pics and specs here:

This unit works just fine, but the frequency and dB st
Has Digital Voltmeter option and Universal Module option. No GPIB
option. I was going to keep this for spare parts, but decided to clear
out some stuff. The only testing I've done on it is to hook up my
GPSDO to channel A. It reads 10,000.001 KHz from a cold start. Make me
an offer.

Hi
Not sure if you could do it with just a straight PRNG or not. The idea is
normally approached as picking the codes you hop between so the errors (phase
and amplitude null out. In practice that may not be any different than random
since you don't really know what the D/A is doing.

Actually, we had someone else asking questions how to build an
ultra stable oscillator as a reference clock for network delay measurements
a couple of months ago. Sear

If you turn on rawstats in ntp.conf, it will collect the data for you.

Thanks for posting this. It kicked off quite a bit of tinkering here

Hi
The 9852 can be dithered from an external source. Of course, to be effective,
you need a source that can calculate and transmit a multi megabit / second bit
stream to do it. That gets you right back to the FPGA. The net result is not as
good as a full blown FPGA approach, but it is indeed be
