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.
