All the channels in the data file with their current user annotation. WINDAQ Waveform Browser Select an annotation for editing from this list… Compression Allows the waveform data file to be compressed: a) entirely onto one screen width or b) to any given ratio. To enable waveform compression: …and edit it here. 1. Point to the Edit menu and drag down to Compression…. The top portion of the Channel Annotation dialog box displays all the channels in the data file along with their current user annotation. To edit a channel’s annotation, highlight (click) on the annotation in the list at the top of the window and perform the editing in the Annotation = box at the bottom of the window. When enabled, the waveform compression dialog box is displayed on the screen: Activating the OK button accepts all of the editing you have done and closes this box. Compression Onto One Screen Width To achieve waveform data file compression so that the entire file is compressed onto one screen width: Activating the Cancel button closes this box and ignores any editing changes made. Click the Maximum command button. Note that the display annotation options can be enabled in virtually any combination to provide the desired result. However in some instances, one annotation option will override another. For example, it is not possible to enable both limit & frequency display and acquisition assignments. When limit & frequency display is enabled, it will be automatically disabled when you attempt to enable acquisition assignments, and vice versa. Conversely, time compression can be disabled (causing the data file to be “uncompressed”) just as easily. To disable time compression: Click the 1 command button. When the entire waveform data file is compressed, the following features are also activated: A logical channel number corresponds to a channel number's appearance in a data file. The first channel acquired is the first in the file, the second is the second, etc. In Playback, logical channels are always specified. However, during acquisition you have the ability to acquire any number of channels, not necessarily in sequential order. For example, you may have acquired channels 0, 2, and 3. These channel numbers are called physical channels ó relating to the actual physical channel number that provided the waveform. Their logical channel numbers are 1, 2, and 3. When acquisition assignments are active, L=P means logical channel number L is assigned to physical channel number P. 1. The entire waveform data file fits within one screen width. 2. The cursor will not automatically be displayed, it must be manually enabled. 3. The ← and → cursor control keys are active, allowing the cursor to be moved in a left or right direction across the waveform(s). 4. The cursor position at any given location on the screen will define the center of the screen when the screen is expanded by entering a lower compression factor. Acquisition assignments annotation provides a convenient method of determining, for any given waveform, which physical channel number provided the signal. 5. The fully compressed file display is saved in memory to allow fast reentry when moving between lower (or uncompressed), and the full 52
