With the acquire_iq.jl script, @zsoerenm noticed that there are subtle biases in the data. They are both static and dynamic. This appears in the first baseband loopback as well. This appears to have not been as observed when performing loopback from the XTRX in the carrier. While using loopback from an XTRX in the XYNC, this issue is more pronounced. Example:
The offset can be more clearly seen when there is no signal (in this case, failure to acquire at 800MHz):
