Input normalizers are used for checking or adjusting the input capacitance of oscilloscopes, or oscilloscope plug-in units, where high impedance attenuator probes may be used. They could be called "dummy probes". Input capacitance should be adjusted for each setting of the input attenuator switch, so that you do not need to readjust an input probe each time the attenuator setting is changed.
Different oscilloscope types have different nominal values of input capacitance, so require different input normalizers.
