Hello,
I must say that I am a bit frustrated.
When I purchased multiple E310 units it was with the hope I will be able to
synchronize them mainly based on:
https://kb.ettus.com/Synchronization_and_MIMO_Capability_with_USRP_Devices,
it shows the E310 as MIMO capable and having a reference clock input.
Of course, now I know that not to be true. At least the reference clock
part. It seems that the MIMO part might be incorrect as well.
If I hack the clock and patch an external clock connector to be used
instead of the internal TCXO will I be able, using existing UHD software
and firmware, to synchronize multiple E310 units?
I will be able to provide a common clock to multiple units and I will be
able to provide a 1-PPS signal through the SYNC pins of multiple units that
is generated from the same common clock.
I need these E310 to transmit and have their base-band samples perfectly
time aligned.
How is multi-chip synchronization of the AD9361 devices being done by UHD?
By using the SYNC pin and setting usrp->set_time_source("external")? Is it
enough? Do I need to handle it on my own? How?
I figured the internal TCXO frequency of E310 is 40 MHz. Can I provide an
external clock of different frequency? Maybe 10 MHz? Or does it require a
major change in software or firmware?
Does anybody have a different idea how to get E310 units synchronized at
sample level without voiding the warranty and hacking an external clock?
Please help.
Regards,
Ofer Saferman
