Burst Delay
Burst delay is only available for N cycle and infinite burst mode. It is defined as the
time from when the generator receives the trigger signal to starts to output the N
Cycle (or Infinite) burst.
When Burst is enabled, press Type  “N_Cyc” or “Infinite”, then press
to
open the 2/2 menu page and press Delay. Use the numeric keyboard or knob to
input the desired delay. The delay is no less than 0s and no greater than 85s. The
default is 0s.
Burst Trigger Source
Burst trigger source could be internal, external or manual. The generator will
generate a burst output when a trigger signal is received and then wait for the next
trigger.
When Burst is enabled, press Source to select “Int”, “Ext” or “Manual”. The
default setting is “Int”.
1. Internal Trigger
When internal trigger is selected, the generator can only output N cycle burst
and the burst frequency is determined by the “Burst Period”.
2. External Trigger
When external trigger is selected, the generator can output N cycle, infinite or
gated burst. The generator accepts the trigger signal from the
[Mod/FSK/Trig] connector at the rear panel. A burst will be generated once
the connector receives a TTL pulse with specified polarity. To set the TTL pulse
polarity, press SlopeIn to select “Leading” or “Trailing” and the default
setting is “Leading”.
Note that in “Int” and “Manual” triggers, the corresponding menu is TrigOut.
The [Mod/FSK/Trig] connector at the rear panel is used as the output
terminal of trigger signal.
