increments.
Sweep Bound (kHz): {±0 to 42 kHz}
Allows the user to set the acquisition range for the demodulator
Data Rate (bps): {Refer to Technical Specs for Data Rates}
Allows the user to set the Data Rate in bps steps via the Front
Panel Arrows or Keypad.
External Reference (MHz): {Variable Through Data Rate}
Allows the user to select the external clock frequency in MHz.
Ref Source: {INTERNAL, EXTERNAL}
