Phase coherence (R&S
®
SMU-B90 option)
The R&S
®
SMU-B90 provides phase-coherent RF outputs of two or more RF paths for one or more instruments with I/Q modulation.
The R&S
®
SMU-B90 option can be installed in any R&S
®
SMU200A with serial number 103001 or higher.
internal
This mode corresponds to normal
operation. Each RF path uses its internal
local oscillator.
external
An external signal is used for path A. With
a two-path instrument, the internal local
oscillator signal is used for path B.
coupled A –> B
The local oscillator signal of path A is also
used for path B (only for two-path
instruments).
Coupling modes
externally coupled A –> B
An external signal is input at the LO IN
connector and used for the coupled paths
A and B (only for two-path instruments).
The internal local oscillator signal used
with path A is also available on the LO
OUT connector (in order to couple two
instruments).
on
LO out state
The LO OUT signal is switched off.
