2.3 Digitizer firmware (DGT option)
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 U5309A 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 card cannot accept a new trigger event. The re-arm time is provided in the U5309A's U5309A
datasheet.
Program examples for Single record or multi-records acquisitions are available:

For IVI-C C
For IVI.NET
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.

Table 2.2 - Maximum number of samples which can be recorded per channel, depending on ordered memory
option.
For technical reasons, a certain acquisition memory overhead is required for each waveform, reducing
the available memory by a small amount.
