That is not always true, actually it depends on when and where you are
going to measure a channel, For example in a office during a day,
channel could change several times in a second. So for indoor
applications a channel sounder should be as fast as possible.
I can refer you to these papers to study more channe behavior:
K.Pahlavan, et.al. Indoor Geolocation Science and Technology
N.Patwari, et.al. Robust Location Distinction using Temporal Link
Signatures
you can also see our website for more information and papers:

That’s correct Hamed. I don’t disagree with what you just wrote. By
“consistent with variations in the channel” in the message prior to the
last
one, I was implying at a meaningful rate. So probing an indoor channel
1000
times a second at peak people-traffic times is more than adequate. And
between successive “probes” you have enough time to transfer the
captured
sequence over the USB at a slower rate than the max. sampling rate of 64
MSamples per second in the Rx. But this assumes you can store about 2kB
of
data on the FPGA.
