Burst Trigger Source
Burst trigger source can be internal, external, or manual. The generator will generate
a burst output when a trigger signal is received, and then it waits for the next trigger
signal. After the burst function is enabled, tap the Source to select "Internal",
"External", or "Manual". The default is "Internal".
1. Internal Trigger
When internal trigger is selected, the generator can only output N cycle burst,
and the output burst frequency is determined by the "Burst Period".
Tap the Trig Out menu label to select "RisEdge" or "FallEdge".
The rear-panel [CH1/Sync/Ext Mod/Trig/FSK] connector will output the
trigger signal with a specified edge. If you select "Off", the trigger output is
disabled.
2. External Trigger
When external trigger is selected, the generator can only output N cycle burst,
Infinite burst, or Gated burst. The signal generator receives the trigger signal
input from the rear-panel [CH1/Sync/Ext Mod/Trig/FSK] connector. Once it
receives a TTL pulse with a specified polarity, a burst output is initiated. To
specify the polarity of the TTL pulse, tap Trig In to select "RisEdge" or
"FallEdge". By default, it is "RisEdge".
3. Manual Trigger
When manual trigger is selected, the generator can output N cycle burst or
Infinite burst. When you press Trig on the front panel for one time, one burst
output is immediately launched for the corresponding channel (if enabled
currently).
Tap the Trig Out menu label to select "RisEdge" or "FallEdge".
The rear-panel [CH1/Sync/Ext Mod/Trig/FSK] connector will output the
trigger signal with a specified edge. If you select "Off", the trigger output is
disabled.
