Signal Generator Overview
Rear Panel
9. TRIGGER OUT
This BNC connector outputs a TTL signal that is high at the start of a dwell sequence or when
waiting for a point trigger in manual sweep mode. The signal is low when the dwell is over, or
when a point trigger is received. The low-frequency (LF) sweep trigger output can be a high or
low 4 µs pulse.
10. TRIGGER IN
This BNC connector accepts a TTL signal used for point-to-point triggering in manual sweep
mode or a low-frequency (LF) sweep in external sweep mode. Triggering can occur on either
the positive or negative edge of the TTL signal start. The damage level is ≤ −4 V or ≥ +10 V.
11. SOURCE SETTLED OUTPUT
This BNC connector provides an open-collector output indicating when the signal generator
has settled to a new frequency or power level. A high pulse indicates that the source has
settled.
