Phase coherence

The R&S

BTC provides phase-coherent RF outputs for the two RF paths or two or more instruments. For frequencies above 200 MHz,

the LO output and input frequency are set to the output frequency.

LO coupling modes

This mode corresponds to internal

LO operation in path A and path B.

A, B internal

This mode corresponds to internal

LO operation in path A, and LO of path B

is coupled to path A.

A internal,

A → B coupled

This mode corresponds to external

LO operation at the LO IN connector in

path A and internal LO operation in path B.

A external,

B internal

This mode corresponds to external

LO operation at the REF/LO IN connector

in path A and path B.

A external,

A → B coupled

REF/LO OUT states

The active LO signal of path B can be

routed to the LO OUT connector (in order

to couple two or more instruments).
