after we successfully circumvented decoupler/receiver phase problem, we
ran into another one with the transmitter (AC250 broadband).
Briefly: when we set the receiver phase to +x and cycle the transmitter
(+x, +y, -x, -y), the resulting signal is about 10% of the single scan
rather than 0. When transmitter is set to +x and the receiver is cycled,
full cancellation occurs.
Also, when the receiver is at +x and the transmitter is cycled between
(+x, -x) or between (+y, -y), the resulting signal is non-zero - just
like during full transmitter cycling.
Has anyone else seen this with their transmitter ? Any suggestions what
can be done other than avoiding phase cycling altogether ?
Thanks in advance,
