PwrPak7 Strobe Specifications

All of the PwrPak7 strobe signals are available on the 26 pin D-SUB high density connector.

PwrPak7 Strobes Description
Strobes	Input/Output	Factory Default	Comment
EVENT_IN1 EVENT_IN2 EVENT_IN3	Input Leading edge triggered	Active low	Input marks for which a pulse greater than 150 ns triggers certain logs to be generated. (Refer to the MARKPOS, MARK2POS, MARK3POS, MARK1TIME, MARK2TIME and MARK3TIME logs and ONMARK trigger.) Polarity is configurable using the EVENTINCONTROL command.
EVENT_OUT1 EVENT_OUT2 EVENT_OUT3	Output	Active low	Programmable variable frequency outputs ranging from 0 Hz to 1 MHz (refer to the EVENTOUTCONTROL command). If your application requires a higher frequency defined pulse (i.e. always 10 MHz at 50% duty cycle), the waveform can be regenerated external to the PwrPak7 by using a Schmitt trigger or buffer with appropriate limits set on the output line.
PPS	Output	Active low	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

All signal I/O are at LVCMOS levels.
