Rohde & Schwarz R&S
®
SMW200A Vector Signal Generator
Measured RF frequency response with internal baseband I/Q.
Analog I/Q inputs
For each installed RF path A or B, one pair of I and Q inputs is available on the front panel (single-ended input mode). With the
R&S
®
SMW-K739 option installed, the input mode for RF path A can also be switched to differential. In this mode, all four available
connectors are used for RF path A.
Analog I/Q input signals are directly applied to the analog I/Q modulation circuit and are not routed through the baseband section of
the R&S
®
SMW200A.
