Measurement of the FM Multiplex signal power
|
| Type of analysis |
DSP sampling of the multiplex FM signal at 500,000 samples / sec. Calculation of the sliding mean of the instantaneous power over one minute conforming to the CCIR recommendation n°450-1.
|
| Accuracy |
+/- 0.2dB typical +/- 0.4 dB guaranteed for powers from 0dB to +12dB. |
Measurement of the FM Multiplex signal overshoots
|
| Type of analysis |
DSP sampling of the multiplex FM signal at 500KHz.
|
| Unit |
The NAVIGATOR HD displays the sliding mean overshoot rate over one minute in ppm (reference is unit time = 1) |
| Threshold |
75KHz +/- 5KHz, with RDS deviation = 4KHz, no pilot modulation |
