GT7800 Strobe Specifications

The GT7800 strobe signals are available on the EVENT BNC connectors.

GT7800 Strobes Description

Strobes	Input/Output	Factory Default	Comment
EVENT_IN1	Input Leading edge triggered	Active low	Input mark for which a pulse greater than 150 ns triggers certain logs to be generated. (Refer to the MARKPOS log, MARK1TIME log, and ONMARK trigger.) Polarity is configurable using the EVENTINCONTROL command. 50 Ω nominal impedance 1 GHz maximum
EVENT_OUT2	Output	Active low	Programmable variable frequency outputs ranging from 0 Hz to 50 MHz (refer to the EVENTOUTCONTROL command).

EVENT IN 2 and EVENT OUT 1 are not active.
