5. DB READINGS SCREEN
The dB readings screen contains all the dB RMS readings performed in the FMCS-1, the readings in white are de-emphasized, the yellow readings are
flat or wideband.
SCREEN DISPLAY DATA
RF Level: Depending on which RF Input is selected displays the dB level at the A/D Input, the input begins overloading at +3.0dB.
AM Noise: AM modulation present on the FM carrier, this reading is de-emphasized by definition.
SYNC Noise: AM modulation present on the FM carrier, this reading is wideband.
Total, Pilot, 38 kHz, L, R, L+R, L-R: All readings are referenced to 0dB = 100% modulation or 75 kHz deviation.
Sep, XTalk: Separation and Crosstalk readings are the difference between the flat Left and Right, or L+R and L-R readings.
SCREEN SELECTABLE DATA
None
6. STEREO BARGRAPH SCREEN
SCREEN DISPLAY DATA
Total, Pilot, Left, Right, L+R, and L-R: Peak Modulation bar graphs display the Peak (Red), Average (Yellow), and Min (Green) modulation data.
All readings a referenced to 100% at 75 kHz deviation.
SCREEN SELECTABLE DATA
None
