Input Decoding
Selects the signal source used for the R8100 frequency counter and decode functions. When set to Internal
the recovered audio or tones from a demodulated received signal are used as the signal source. The
External setting directs an externally applied signal at the Meter In port to the R8100 frequency counter
and decode circuits.
Input Impedance
Selects the input impedance for the Meter In port to either 600 Ω or 1 MΩ. Note: To prevent damage to
the R8100 the 600 Ohm input impedance is restricted to AC and DC ranges of 10 Volts or less. Both the
AC and DC voltmeters must be set to a range of 10 Volts or less before 600 Ohms can be selected.
Reference Clock Mode
Selects the mode for the 10 MHz Ref In/Out connector at the side of the R8100. “Output” routes the
internal 10 MHz time base signal to the 10 MHz Ref In/Out connector for use as a frequency reference by
