Timing principle using Burst mode

Each Channel can be independently set to Burst mode. In the following example Burst trigger has

been set to IN1, Burst pulse number to 5 and Burst period to TB

Figure - 9. Burst Mode Timing

The minimal burst period value is 1000ns. But it has to be noticed that this value depends on the

Burst trigger period value and on the Burst pulse number.

𝒎𝒊𝒏

𝟐 ∗ 𝑷𝒖𝒍𝒔𝒆

So, to get a TBmin = 1000ns we have to configure the device as follows:

• T

Trigger

min = Pulse nbr * 2000ns

• Pulse nbr min = 2

• T

trigger

min = 4000ns

As depicted on Figure - 9, in the case of a generation of pulse train (Burst Mode) on a channel, the

Gate In signal can inhibit some pulses among the pulse train.
