MAIN OUT

MAIN OUT

is the 50 Ω or

600 Ω output from the main
generator. It will provide up
to 20 V p-p into a high-
impedance load or 10 V p-p
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
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.

EXT TRIG

EXT TRIG

is the external

trigger input for the non-
continuous modes (trigger,
gate, sweep, FSK and hop)
and for synchronizing the
generator as a slave to an
external master generator.
