6.2.5.4 Measurement examples: using an external mixer
Measurement example 1: two-port mixer
The following example demonstrates the basic operation of an external two-port mixer
as well as the required settings. A sine wave signal with f = 14.5
GHz is applied to the
input of a multiplier. The spectrum at the multiplier output is to be recorded in the range
of 52
GHz to 60 GHz using a 2-port mixer for the V band. The mixer used is a double-
diode mixer. The example of operation is described in the following steps:
●
"To set up the measurement" on page 421
●
"To activate and configure the external mixer" on page 422
●
"To take into account the cable loss in the IF path" on page 422

1. Connect the [LO OUT / IF IN] output of the R&S FSV/A to the [LO/IF] port of the
external mixer.
2. Connect the multiplier to the RF input of the external mixer.
3. Apply a sine wave signal with f = 14.5 GHz to the input of the multiplier.
