9.10 Trigger Output Edge
In sweep mode, when "Internal" or "Manual" trigger source is selected, the generator
will output a TTL compatible signal with specified edge from the
[FSK/Trig/Sync/Extmod] connector on the rear panel.
Internal and Manual Trigger:
The generator outputs a Pulse waveform from the [FSK/Trig/Sync/Extmod] connector
on the rear panel at the beginning of the Sweep. The trigger period depends on the
specified frequency sweep time, return time, and hold time. When the output signal
frequency is less than the specified mark frequency, there will output the low level signal
from the [FSK/Trig/Sync/Extmod] connector on the rear panel. When the output signal
frequency is at or greater than the specified mark frequency, the signal outputs on the
[FSK/Trig/Sync/Extmod] connector will change from low level to high level.
External Trigger:
The [FSK/Trig/Sync/Extmod] connector is used as the input terminal of external trigger
signal and has no trigger output
