We have Zed Board + FMCOMS3 (AD9361) board here, could you please explain how could we measure TX to RX port isolation ?
What I Tried:
RX LO: 2200MHz
TX CW signal generated from TX2A port at 2202MHz (mean Voltage(2) and Voltage(3) in ADI oscilloscope)
RX1A chain gain 0, RX1A port signal checked at Voltage(0) and Voltage(1) in ADI oscilloscope
This is TX2A to RX1A isolation, is this correct way of mearurement?
How can we measure TX1A to RX1A, becoz it will be on same frequency, and in ADI oscilloscope, both TX and RX signal are visible.
