3.7 1PPS Signal Connection
A 1 pulse-per-second (1PPS) signal synchronized with GPS
time is available from the terminal blocks P208 named Radar on
the Processing unit. This 1PPS signal originates from the GPS
receiver within the Sensor unit. The 1PPS signal is buffered and
fed to the P208 connector. The high level is at +5V (unloaded)
with 180 Ohm load source impedance. The low level is at 0V.
The 1PPS signal is active high and has a pulse width of 1 ms.
The 1PPS is generated exactly once every second with its rising
edge synchronized to GPS time. Synchronized with this signal it
