Instruments that include the Input C high-frequency prescaler (FCA3000 Series, FCA3100 Series) or down converter
(MCA3000 Series) provide a subset of measurements for the C input. These measurements are Frequency, Frequency Ratio
(C to A and C to B), Frequency Burst, and Period (Average). Input C is added to the relevant menus on the instrument.
