Use the RADARCONFIG command to configure ER.
Emulated Radar pulses are output through the SMART Antennas
Interface Cable (Optional Accessory) on the next page and the
RADARSTATUS log.
3.3V CMOS
A time synchronization output. This is a pulse where the leading
edge is synchronized to receiver calculated GNSS Time. The
polarity, period and pulse width can be configured using the
PPSCONTROL command.
Voltage Input Low is 0.8V
Voltage Input High is 2V
Input marks for which a pulse greater than 150 ns triggers
certain logs to be generated. (Refer to the MARKPOS and
MARKTIME logs and ONMARK trigger.) Polarity is configurable
using the MARKCONTROL command.
