Instrumentation

This section controls various configuration settings for A/D, P/R and Hardware acceleration.

Acquisition

Try to use Fast Downloading

If checked, the data download from the A/D will start immediately when the board is armed. If the data download rate is low, this may cause DMA timeout errors.

Disable Burst DMA

This option is set at the factory and should not be changed.

Discard Follower Data

If checked the preliminary TOF image will be discarded.

Disable Advanced Follower features

If checked, Follower gates will collect TOF data only.

Match Thickness Type on Parent

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 If checked peak amplitude data will be collected regardless of threshold size. Rising/Falling edge TOF is not valid while this checkbox is checked.

Enable Gate Gains

If checked, the user can adjust the gain on the waveform within a gate region.

Always use Software Trigger when not scanning

If checked, the digital oscilloscopes will always be triggered by ODIS 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 board is ignored until the scan starts. Whether or not a board actually triggers depends on if it is enabled and if appropriate trigger connections and pulser/receiver settings are present.

Allow different trigger modes per channel

If checked, the default trigger mode can be overridden by selecting the trigger modes via the Digital Oscilloscope.

Don't trigger on channels that are not visible

If checked, only the currently visible Scope tab will update when idle. Other channels will not be triggered.

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 properly, the following settings must be correct: 1) C 1) Set the correct axis that is the source of the encoder positions. 2) Set the number of counts per unit. The units used are displayed at the right.

Usually, only

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.
