Burst Modulation

Burst Rate

The burst rate defines the frequency at which internally triggered bursts
are generated. The burst rate frequency defines the interval between
bursts. Used only in the internal triggered burst mode.
Keep in mind that the burst rate is different than the "carrier frequency"
which specifies the frequency of the bursted signal.
œ Burst rate: 10 mHz to 50 kHz. The default is 100 Hz.
œ The burst rate setting is used only when internal triggering is
enabled (triggered mode). The burst rate is ignored when single
triggering or external triggering is enabled.
œ When the single or external trigger source is selected (triggered mode),
the burst count and burst phase remain in effect but the burst rate
is ignored.
œ When the external gate burst source is selected ("gated" burst mode),
the burst count, burst rate, burst phase, and burst trigger source are
ignored (these parameters are used for the triggered burst mode only).
œ It is possible to specify a burst rate which is too fast for the function
generator to output with the specified carrier frequency and burst
count. If the burst rate is too high, the function generator will
internally adjust it as needed to continuously re-trigger the burst.
The adjustment is handled internally by the function generator
(the burst rate displayed or queried will be the same as specified).
