peaks and use the marker selection to quickly demodulate and listen to those peaks. Additionally, on the
Dual Display, the user can simultaneously also view the demodulation scope while tuning the marker
positions.
Note: To ensure audio is demodulated, the marker must be close enough to overlap the R8100 Monitor
Bandwidth around the carrier frequency. Large Span settings increase marker frequency step size,
limiting how close the marker can get to the actual frequency. To minimize step size use the narrowest
span practical when displaying multiple carriers.

The Modulation Scope displays the internally-processed RF modulation waveforms. It automatically
switches between Generator and Monitor modulation depending on which mode is selected. In Duplex

Access the Modulation Scope using the Select Display soft key to bring up the horizontal submenu display
choices. The available adjustments are as follows:
