A-Scans
Generating A-Scan Snapshots from the Digital Oscilloscope
A user can generate an A-Scan from the Digital Oscilloscope by left-clicking on the A-Scan snapshot icon 
above the waveform. This will generate a copy of the currently displayed A-Scan. Any number of A-Scans can be generated.
Saving A-Scan Snapshots
A-Scans generated from the Digital Oscilloscope can be saved by pressing the save button 
at the top right of the A-Scan form. The A-Scan can be saved in a number of file formats, including plain text, CSV, TIFF, PNG or JPG.
Like the main Scope, A-Scan data can be dragged and dropped on various external applications, such as Excel, Word, or Text editors.
A-Scans on Collections
on the image.A-Scans can be generated from collections in two ways: by using the current A-Scan from the Digital Oscilloscope, or by using existing B-Scan data that is contained within a collection. When an A-Scan is generated, a mark is shown on the image representing the position of the A-Scan. The user can generate A-Scans at every point in the collection data if necessary.
Generating A-Scan Snapshots for a Collection
To generate an A-Scan for a collection that does not contain B-Scan data, move your motors so that the motor cursor is over the area of the scan on wish you which to generate an A-Scan. Once at the desired location, either press the A-Scan snapshot icon from the toolbar or right-click at the point and select "A-Scan" from the drop-down menu.
Using Motor Position vs Encoder Position
By default, the A-Scan will use the current motor position to determine the location of the marker on the collection. If desired, the user can use the Encoder position (if available) by selecting the "Get A-Scan Position From" option in Configuration setting. If set for Encoder, the position of the encoder cursor 
will be used instead.
Generating A-Scan Snapshots from a Collection
If the collection has B-Scan data, when the user clicks the A-Scan Icon or selects A-Scan from the menu, the mouse cursor will turn into a cross 
. While in this mode, the user can left-click at any point of the image, and the B-Scan data from that point will be used to generate an A-Scan.
A-Scan Overlay
The A-Scans at several points can be overlaid on top of each other by using the "Overlay" menu option. This collapses all the A-Scans form a collection to a single form. The A-Scans can then be compared directly. The A-Scan will show numbers representing each waveform present: when any particular waveform is selected, the gate tree associated with that waveform is displayed.
To activate overlay, right-click on any A-Scan mark and select the "Overlay" menu item. This will collapse the A-Scan forms into a single form with all A-Scans overlapped. To reverse the overlay and split the A-Scans back into separate windows, simply right-click on an A-Scan mark and select "Overlay" again.
Loading/Saving Collection A-Scan Snapshots
A-Scans created with collections will be saved with the collection when saved, and will be recalled when the collection is loaded. Whether or not the A-Scan forms are displayed on loading depends on the Configuration settings.
B-Scan Cross Sections
A third type of A-Scan is created when doing a cross-section of an existing set of B-Scan data. When in Cross-Section mode, an A-Scan will appear that tracks the location of the cursor over the B-Scan image. The location of the current waveform being displayed is shown as green on the B-Scan image. As the user moves the mouse across the waveform, a red line is shown on the A-Scan form indicating the location in time.
When the user leaves cross-section mode, the Cross-Section A-Scan will remain until closed. This lets the user save the data to a separate file if desired.
Measurement on A-Scans
All A-Scans (including the Digital Oscilloscope have a Measurement tool that can be toggled on and off 
. When active, this icon will turn red and a pair of measurement cursors will appear on the A-Scan, one purple, and the other blue. The user can move these A-Scan cursors on the scope to measure the amplitudes and time offsets of features of interest.
When active, the measurement tools show the following information:
- position in time or distance of the vertical cursors at the (at bottom).
- position in %FSH or voltage of the horizontal cursors (at left).
- difference between cursor 1 and cursor 2 in time/distance (at top).
- difference between cursor 1 and cursor 2 in %FSH/Volts (at left).
A second button 
allows the user to determine if the horizontal measurements will track the amplitude as they are moved. If activated, as the user moves the vertical line back and forth, the horizontal line (representing amplitude) will automatically track with the amplitude of the waveform at the given point.
