Sygnał prędkości 130 impulsów = 1km/h
5.2 True ground speed and theoretical
ground speed
5.2.1 The signal shall be a square wave with a duty
cycle between 20 % and 80 %, and with rise and fall
times less than 1 ms.
5.2.2 The signal level of the square wave “mark”
(high) shall be greater than 6,3 V and the “space”
(low) shall be less than 1,5 V. The output source
impedance at “space” (low) shall be 100 7 ± 10 7.
The load impedance shall be greater than 3 k7.
5.2.3 At speeds greater than 1 km/h, the speed shall
be represented by 130 pulses/m ± 5 %
(130 Hz/m/s ± 5 %) in a standard calibration test.
