Hi all.

I am new to phase noise measurement but bought a PN2060A to try it. Awesome device.

I have made a blog post about it.

I was in contact with Yanjun today. He is currently on summer holiday. However, he did say he has some of the PN2060A for US$480, two of the PN2060B for US$780 and is working on PN2060C/D. To quote, "Currently I am focused on the development of PN2060C/D. Hopefully, It can be finished within 1-1.5 months. For PN2060C/D, one is with 2 ADC chips, and the other one is with 4 ADC chips."

Hi Drew
After my 3048 died. I have  built my own PNA from FPGA bits and boards I have lying around  (I do that for a living) , it worked OK , I just fed raw samples to python and that did the rest.
However , compared to my mass of bits and leads,  the PN2060 is just too easy and compact so I just bought one.

Apparently this is PCB Rev 1.1 so we'll see how it goes.

I'd be intrested to hear what you used for the front end given the AD DC1525A-A eval board used by Andy Holme is hard to find now (the FPGA part is more straightforward to substitute).  I've got a rather non-standard 3048 setup (HP3563A as DSA not 3561) which works well, although at times the DSA is painfully slow. At times I would be interested in a direct digital comparison option!

As PN2060C with now V1.1 PCB.

What I am missing:

-  the additional HW parts as required to start with a simple measurement, So to organize as DIY  :palm: At the end of this parts, measurement & validation could start but not before.

- The USB 3 connections are not isolated and draw high currents. No battery solution (galvanic isolation) seen so far.

- the real given required SW parts as still DIY and SW maintenance is unknown ??

- this means, this looks IMHO not a ready to go solution.

or I am wrong?

Hi all,
Does someone tested phase noise on 800MHz directly by PN2060C?
I want to by one, but I don’t know how the performance on 800MHz.  How much it will be about  performance degrade.

Thank a lot.
