I/Q input connectors
Input connectors for the single ended (I/Q) or differential (I/Q, I/Q BAR) baseband signal (Figure "Rear view of the R&S SZU", (6)). These connectors are SMA coaxial connectors with 50 Ohm impedance.
The I/Q input connectors receive the single-ended signal, or the positive signal components of the differential signal. The I/Q BAR connectors receive the negative signal components of the differential signal.
