I'm buliding a system that switches the RF input, several times per
second, between the actual
signal, and a stable reference source.
On a USRP2, what kind of latency is there between the antenna input, and
data arriving at the
head of the signal processing chain?
Small errors at the 'edge' of the switching time are acceptable, but I
don't want to get into a situation
where my *notion* of whether the input is connected to the source or
the reference is horribly
out of what.
Can I use the GPIO stuff to give me better confidence of adequate
synchronization between the
actual data, and the state of the input?
