AUXILIARY OUTPUTS
AUX OUT
CMOS/TTL levels with symmetry and frequency of
main output and phase of Start-Stop phase setting.
TRIG/SWEEP OUT
Multi-function output depending upon mode. Except in
Sweep mode, the output is that of the Trigger Gener-

In Sweep mode the output is a 3-level waveform,
changing from high (+4V) to low (0V) at the start of
sweep, with narrow 1V pulses at each marker point.
