TOTAL MODULATION
Ballistics
Total Modulation is peak-responding and incorporates a peak-hold function.
Display Gain
Total Modulation readout shows peaks between 16% nd 130% in 3% increments. The button below the display can be used to switch in an additiona gain of X10 (20dB).
AM Modulation
Panel Readouts for AM Carrier Modulation, Asymmetrical AM Modulation and AM Display Errors.
FM Modulation
Total Modulation indication of 100% factory calibrated to ±75kHz deviation.
Multipath Detector
A multipath Detector has been built in with a Multipath display near the frequency readout. The Detector is interconnected with the Toatal Modulation display.
Additional Subcarriers
The Sentinel can be switched to monitor SCA or RDS subcarriers.
LEFT AND RIGHT CHANNELS
Ballistics
Left and Right Channel displays are peak-responding, and will closely follow the Total Modulation dispplay in response to program peak content.
Scaling / Gain
Left and Right Chanel bargraphs are dB-linera displays with a normal range of +10dB to -29dB. The button beneath the readout switches-in an additional 20dB Gain, changing the scaling to a range of -10dB to -49dB.
L+R STEREO SUM / L-R DIFFERENCE
Left and Right Channel program signals are matrixed into Left + Right “Sum”, and Left - Right “Difference” channels, and displayed alongside the the independent Left and Right Channel readouts.
QDM MONAURAL
Stereo Channel Phasing
To approximate non-coherent, acoustical combination of Left and Right Channel program signals, Inovonics has developed the “QDM” or Quadrature-Derived Monaural Channel.
