Hi Chris,
Can you briefly explain in what exactly consists the Software PLL?
All,
I've been trying to set both Tx and Rx to the same frequency and sending a
sinusoid to try to measure the frequency offset, but it does not seem to
work... it looks like as both Tx and Rx are driven by the same clock
The one used on USRPs shipping now is 20 ppm with this part number --
EC2620ETTS-64.000M
From Ecliptek. They are pin compatible.

By the way, could someone tell me what is the part number of the VCTCXO
shipped with USRP Rev 4.5? In the bill of materials of the trunk I see
"CTX286LVCT-ND", which seems to correspond to CB3LV-3C-64M in the
manufacturer's nomenclature.

Thanks everyone for your answer!
I understand that some frequency offset will always be there on the Rx
but I would like to minimize it.
However, the main problem on my system is on the Tx path as the
receiver (which I can not modify) is not having any frequency
correction algorithm, so I must Tx
Hi,
Can some one explain in a little bit detail how this software PLL can be
implemented and how this synchronization can be acheived. I am using RFX2400
and facing same problem.
First I tried to solve the problem by calculating the frequency shift at
receiver end by using usrp_fft.py and then b

I am having lots of issues with the USRP 64MHz (20ppm) on board oscillator
which does not allow me to get exact and constant RF frequencies out of the
