Figure 2.25: Modulation Levels
Modulation levels.
See Figure 2.25 . Bar graphs display the percentage of L+R modulation, PDM
(magnitude) and I/Q modulation for the transmitter. I/Q bar graphs will show levels in DRM or
IBOC mode only.
The level shown in yellow represents the currently measured peak modulation level, with the RMS
level shown in green. An actual RMS value is displayed below the meter).
The red markers represent the most recently recorded maximum peak level. The actual peak values
are displayed in red below the meter. For L+R and I/Q modulation, both positive and negative peaks
are shown.
There are no interactive tools (cursors, fine/coarse adjustments) for this display.
