Hi
Phase is what drives an ADEV measurement ( frequency from phase ….). Phase
noise the noise
at a specific offset from a carrier, often normalized to a 1 Hz bandwidth.
Phase noise is a different
measure than “phase”. ( = they are not the same thing ).
Indeed a single mixer can be used as the h
Learned Gentleman,
I've read several articles on phase noise but I'm lost.
I need a *Ding-Dong* school explanation of what it is, why it's important and
how one goes about measuring it.

Esteemed Members,
Several years ago I had a late model HP 105B that was configured with the HP

I've sent it to the KO4BB website for posting.
I had misplaced my files and had thought I'd lost them in a hard drive crash.

When I worked for Agilent, I had full access for "free" to
all these tools, and access to their designers, etc.
Nevertheless, the time commitment to learn these tools
is prohibitive to any engineer who is responsible for
designing the complete product, not just designing a chip.

Oh, not really.
But if you always wanted to experiment with harmonic balance,
nonlinear noise and other things that your LTspice cannot do, then
Keysight currently offers 3 month trial licenses for ADS for home office use

Hi
The main point is that these Rb’s (not just the PRS-10) are not really
set up for what you are trying to do. A proper GPSDO will do a much
better job than something like this. ( GPS into PRS-10 != GPSDO ).
There are a number of sub-variants of the PRS-10 (and the other telecom
Rb’s) so knowi
Hi Bob,
If I am understanding you correctly, it is normal operation that the time
tagging stops working, and that the PPS out should not phase lock to the
PPS-in? It is perfectly fine in my application that the PPS out has a
fixed non zero offet to the average GPS PPS signal (obviously any

Hi
Backing up a little bit …. the PPS in on these telecom Rb’s is designed to
easily get the part set on frequency. It’s not designed for a GPSDO
application.
What you are seeing is consistent with that “application target”.

Hi all,
Thank you for your feedback. I found the schematics for the PRS-10 online,
and the output is 5V HCMOS.
signal :
locked --> hc08 inhc08 out --> hc14 in hc14 out --> 4x 240 ohm
resistors -> output pin
PPS--> hc08 in
Which brings me to my next question. I have been running
Hi Skip.
Does the Austron even recognise the *IDN? query that Ni-Max uses to
identify instruments? Information on those is "thin" on the web.
Is your ENET-GPIB able to work in analyser mode, so you can see exactly
what's happening on the bus as the PC scans for devices?
Check the cables. If I
