MAIN OUT is the 50 Ω or		trigger input for the non-

into a matched 50 Ω or
600 Ω load. It can tolerate a
short circuit for 60 seconds.
AUX OUT
The AUX OUT socket
provides a two-level TTL
and CMOS compatible
signal, synchronous with
the signal from the	shx0006f.gif
MAIN OUT socket.

The symmetry of the AUX OUT signal is the same as that set for the main output but you can adjust the phase relationship between MAIN OUT and AUX OUT using the PHASE setting in the TRIG menu.

AUX OUT logic levels are nominally 0 V and 5 V from typically 50 Ω. AUX OUT will withstand a short-circuit.
