Fixed Lo; Fixed If; Image Rejection - Rohde & Schwarz FS-K30 Software Manual

R&S FS-K30
2.4.1.5

Fixed LO

The Fixed LO is the fixed local oscillator frequency for measurement Modes.
I Fixed LO, IF = RF + LO
I Fixed LO, IF = abs(RF – LO)
Changing the Fixed LO will replace all LO values in the Frequencies List (the list of
measurement steps).
2.4.1.6

Fixed IF

The Fixed IF is the fixed intermediate frequency for measurement Modes .
I Fixed IF, LO = RF + IF
I Fixed IF, LO = abs(RF – IF)
Changing the Fixed IF will replace all IF values in the Frequencies List (the list of
measurement steps).
2.4.1.7

Image Rejection

The Image Rejection is the suppression applied to the second sideband during
calculations for measurement Modes:
I Fixed IF, LO = RF + IF
I Fixed IF, LO = abs(RF – IF)
I Fixed LO, IF = RF + LO
I Fixed LO, IF = abs(RF – LO)
