Instrumentation
This section controls various configuration settings for A/D, P/R and Hardware acceleration.
Acquisition
| Feature | Example | ODIS-IC? | ODIS-NDT? | Description |
|---|---|---|---|---|
| Try to use Fast Downloading | N/A | x | x | If checked, the data download from the A/D will start immediately when the board is armed. If the Number of Points per Download are not collected within one second, a DMA timeout will occur. If not checked, the system will wait for sufficient data to be collected on the A/D board. In this case, the Scan timeout will cancel the scan if insufficient data is collected. It is recommended to uncheck this option when running predominantly Rotational scans or when motor motion is required to be slow. |
| Disable Burst DMA | N/A | x | x | This option is set at the factory and should not be changed. |
| Discard Follower Data | TBD | x | x | If checked the any TOF crossing image data will be discarded from Follower gates. |
| Disable Advanced Follower features | TBD | x | x | If checked, Follower gates will collect TOF crossing data only, and not collect any Peak, TOF to peak, or other data. |
| Match Thickness Type on Parent | TBD | x | x | If checked, the Thickness type being collected will be matched on the parent Follower (e.g. Peak-to-Peak, Edge-to-Edge, etc.), rather than always using the Edge crossing. This will be disabled if the "Disable Advanced Follower Features" option is checked. |
| Ignore Peak Thresholds | TBD | x | x | If checked, peak amplitude data will be collected regardless of the gate threshold setting, giving data gates an effected threshold of zero. Rising/Falling Edge TOF Settings will be erratic unless a clear signal is present. |
| Enable Gate Gains | TBD | x | x | If checked, the user can adjust the gain on the waveform within a gate region. This overrides any TGC settings present. |
| Use Quick Setup | TBD | x | x | Deprecated, to be removed. |
| Always use Software Trigger when not scanning | TBD | x | x | If checked, the digital oscilloscope will always be triggered by ODIS using a Software trigger when not in a scan, at a rate of approximately 20 times a second (this will vary depending on scope and gate settings). The trigger setting for the A/D board is ignored until the scan starts. If not checked, the Trigger mode as defined on the Digital Oscilloscope applies. Whether or not a board actually triggers in this mode depends on if it is enabled and if appropriate trigger connections and pulser/receiver settings are present. Otherwise a Timeout error will be displayed on the scope. |
| Allow different trigger modes per device | TBD | x | x | If checked, the default trigger mode specified in the Scan Manager Options page can be overridden by selecting the trigger modes via the Digital Oscilloscope. Not applicable if there is only one A/D board in the system. |
| Don't trigger on devices that are not visible | TBD | x | x | If checked, only the currently visible Scope tab will update when idle. Other channels will not be triggered. Uncheck this if the trigger to one A/D board is dependent on an external trigger from a different A/D board. Not applicable if there is only one A/D board in the system. |
| A/D Encoders | ||||
| Use Quick Setup | TBD | x | x | Deprecated, to be removed. |
A/D Encoder resolutions
This sets the counts per physical unit that the A/D board(s) use to to calculate increments when using Encoder Triggering.
In order to configure Encoder resolutions, the following settings must be correct:
- Enable Encoders by clicking on the "Exists" checkbox
- Set the correct axis that is the source of the encoder positions.
- Set the number of counts per unit. The units used are displayed at the right.
Usually, only the Primary encoder axis needs to be set. In cases where Encoder triggering is possible on another axis, configure the Secondary axis in the same way.
P/R
If Idle, Disable P/Rs
This option can be used to turn off the P/R(s) after a certain time has passed without any activity detected. This helps prevent long-term wear on the pulser and transducers. Set to "Never" to keep the pulser on at all times. If a scan is running, this parameter is ignored.
Clamp Pulser Energy
This is a factory setting and should not be changed.
Enable Slave Setting of the Secondary PR
If checked, the secondary P/R of a mult-channel DPR (e.g. DPR500) can be slaved to the primary. Otherwise, both P/Rs act independently.
GPU
GPU settings are disabled as of this writing.
