IF Dithering
Lets you turn IF Dithering on or off. This is a technique used in unpreselected
instruments (such as Keysight’s modular instruments) to enhance the rejection of
images and internally-generated spurious signals.

Image Protection
Lets you turn IF Protection on or off. This is a technique used in unpreselected
instruments (such as Keysight’s modular instruments) to detect and suppress
images and spurs that may be present in non-preselected hardware.
IF Protection takes two sweeps and by correlating the data between them, provides
a single, correct power-versus-frequency trace.
