Scope To

Settling

Oscilloscope To selects the signal source for the Oscilloscope. This allows you to
bypass certain sections of the AF analyzer's circuitry when viewing and
measuring a signal. It also allows you to select measurement paths that include
additional gain stages, improving the oscilloscope's resolution when measuring
low-level signals.
