Events Summary
The following table describes the event types supported by NI digital waveform
generator/analyzers. The Used In column indicates which types of operations can
use an event type.
| Event Name |
Used In |
Description |
| Data Active Event |
Generation |
The Data Active event indicates when the Pattern Generation Engine is generating data. If the Pattern Generation Engine is waiting for a trigger or is paused, the Data Active event is deasserted. When the Pattern Generation Engine is generating data, the Data Active event is asserted, synchronous with the data. |
| Marker Event |
Generation |
The Marker event is a general-purpose event that is configured within a
generation script. The Marker event can be asserted synchronous to any even numbered sample within a waveform within a
script. For example, the Marker event can be asserted when sample 432 of
waveform A is generated. You can create multiple Marker events for use in
your application.
 |
Note When using DDR mode,
marker positions will have a quantization twice that
of SDR mode. Refer to your device specifications for more information
about marker quantization. |
|
| Ready for Start Event |
Acquisition, Generation |
For both acquisition and generation, the Ready For Start event indicates that the NI digital waveform/generator analyzer
is configured and ready to receive a Start trigger. |
| Ready for Advance Event |
Acquisition |
An event that indicates when the device enters its Wait for
Advance Trigger state, which indicates that the acquisition of the previous record
is complete. |
| End of Record Event |
Acquisition |
An event that indicates when the device enters its
Record Complete state, which indicates that the current record has been acquired. |
| Sample Error Event |
Hardware Comparison |
An event that indicates when the device detects a sample where the actual response and the expected response do not match. |
