The following example assume a four-port analyzer with independent source
ports no. 1 and 3. Moreover, an external generator Gen 1 must be connected
to the analyzer and configured.
FREQ:CONV MIXER
Activates scalar mixer measurement.
*RST; FREQ:CONV:MIX:STAG 2
Select a mixer measurement with two mixer stages.
FREQ:CONV:MIX:RFPort 1; IFPort 2
Select the analyzer port 1 as a source port for the RF signal, port 2 as a
receive port for the IF signal.
FREQ:CONV:MIX:LOPort PORT, 3; LOPort2 GEN, 1
Select port 3 as source port for the local oscillator LO1 and generator 1 as
source for LO 2.
FREQ:CONV:MIX:RFMultiplier 2, 1; LOMultiplier1 2, 1 ; LOMultiplier2 2, 1
Define frequency conversion factors 2 for the RF signals and the LO signals.
FREQ:STARt 1GHz; STOP 2 GHZ
Select a sweep range between 1 and 2 GHz.
FREQ:CONV:MIX:FIXed1 LO1; FIXed2 LO2
Assign fixed frequency settings to the two LO signals.
FREQ:CONV:MIX:FUNDamental RF; MFFixed LO1, 10 MHz; MFFixed LO2, 10 MHz
Assign the channel base frequency (sweep range) to the RF signal, fixed
frequencies of 10 MHz to both LO signals.
FREQ:CONV:MIX:TFRequency1 DCUP; TFRequency2 UCON
Select down-conversion (USB) at the first mixer-stage, up-conversion (USB) at
the second mixer stage.
SOUR:FREQ:CONV:MIX:PMODe RF, FUNDamental; PMODE LO1,
FIXed; PMODe LO2, FIXed; PMODe IF, FUNDamental
Assign the channel base power to the RF and IF signals, a fixed power to the
LO signals.
SOUR:FREQ:CONV:MIX:PMFixed LO1, -20; PMFixed LO2, -10
Define the fixed power levels of the LO signals.
