Burst
You can configure the function generator to output a waveform with a
specified number of cycles, called a burst. You can use burst in one of
two modes: Triggered Burst (also called N Cycle burst) or Gated Burst.
Triggered Burst Mode
Triggered burst mode consists of a specific number of waveform cycles (1
to 50,000) and is always initiated by a trigger event. You can also set the
burst count to “Infinite,” which results in a continuous waveform once
the function generator is triggered.
Three-Cycle Burst Waveform
For bursts, the trigger source can be an external signal, an internal
timer, the key, or a command received from the remote interface.
The input for the external trigger signals is the rear-panel Trig In
connector. This connector accepts TTL-compatible levels and is
referenced to chassis ground (not floating ground). When not used as an
input, the Trig In connector can be configured as an output to enable the
33210A
to trigger other instruments at the same time as its internal
trigger occurs
.
Triggered burst always begins and ends at the same point in the
waveform, called the start phase. A starting phase of 0° corresponds to
the beginning of the waveform record and 360° corresponds to the end
of the waveform record.
