EVM Circuit Overview
The baseband I/Q signals can be measured balanced or unbalanced. The I output is taken from the
unbalanced port J15 (RXBBI) through balun T5 or from the balanced ports of J13 (I+) and J18 (I-).
Likewise, the Q output is taken from the unbalanced port J24 (RXBBQ) through balun T7 or the balanced
ports of J21 (Q+) and J26 (Q-). For balanced mode measurements, jumpers W3, W5, W7 and W9 must
be removed.
