Figure 2.2 - Acquisition sequence using a multi-records. It is possible to miss a trigger at high trigger rate, as
illustrated with trigger 3.
The multi-record acquisition mode enables successive events, occurring within a very short time,
to be captured and stored without loss. A very fast trigger rearm time is a crucial feature for multi-
record acquisitions. Thanks to fast trigger rearm, the SA230E achieves very low "dead time" between
the records of a multi-record acquisition. The "dead time" is the period after the end of an event when
the module cannot accept a new trigger event. The re-arm time is provided in the SA230E's SA230E
datasheet.

Acquisition memory
Data from the ADC is stored in on-board acquisition memory. The amount of memory in use for
acquisition can be programmed and is selectable from 1 point to the full amount of acquisition memory
available.

option.
For technical reasons, a certain acquisition memory overhead is required for each waveform, reducing
the available memory by a small amount.
