anyway it is only for case when there is no space on PCB to add MMCX or even better SMA
<bvernoux>
mainly for antenna
<bvernoux>
for traces it is better to add some to probe with dual Pin
<bvernoux>
+via
<bvernoux>
example on USB HS there is often 2 via so it can be used to probe the impedance with 2 pin
<bvernoux>
also I have a special UFL to SMA male connector in my Calibration Kit
<bvernoux>
Auburn probes has just been shipped ;)
<bvernoux>
I habe bought 2 ;)
<bvernoux>
in order to compare them and check if they are like on paper with full caracterization
<bvernoux>
from 30KHz to 6GHz with s1p & s2p
<bvernoux>
1601pts
<bvernoux>
will be nice to compare to yours
<bvernoux>
to check what we could reach ;)
<azonenberg>
Yeah, I *still* havent had time to assemble that last probe pcb spin
<bvernoux>
there is no hurry
<azonenberg>
Progress is being made, just on so many different fronts each one is moving at a glacial pace :)
<bvernoux>
on my side it is even worse ;)
<bvernoux>
some project in "frozen" state since too much time
<bvernoux>
anyway I have made good progress on NFC next gen chipset ;)
<bvernoux>
so far all is very good
<bvernoux>
i'm working to create a sigrok/pulseview decoder for this chipset ;)
<bvernoux>
as there is so much SPI transaction not documented that I need to spy what happen on my eval board ;)
<bvernoux>
some config are like black magic (and not documented correctly of course) and I want to check/understand all in order to push the chipset to the limits ;)
<bvernoux>
I will documentation that with tutorials of course
<bvernoux>
documentation=>document
<bvernoux>
What I can say if NFC 13.56Mhz on latest PM3 is very far from what there in the spec (or that I have checked with eval board) of the chipset I'm using ;)
<bvernoux>
NFC differential antenna is amazing not only on paper ;)
<bvernoux>
including auto-tuning is clearly some of the killer features ;)
<bvernoux>
I would love to have that on other RF chipset/SDR
