Data Sheet Overview Cursors. Cursors are used to measure the waveform plot. You can put cursors on the selected sheet using the Cursor tab on the Property Page. Cursor readout values indicate the vertical or horizontal value at the cursor location. Vertical cursor position values appear as dX and X. Horizontal cursor position values appear as dY and Y. Gates. Gates define the range over which measurements are computed when waveform data is moved from this sheet to a waveform measurement sheet. Turn on gates by choosing vertical cursors in the Cursor Property dialog and checking the Gate with Vertical Bar Cursors checkbox; then, set gate location by using the mouse to move the cursors. Print Banner To print the full record length of all waveforms in the YT data sheet, select the data sheet and choose Print Banner... in the WaveStar File menu. The Print Banner option is useful when your YT data sheet contains waveforms that are longer than the width of the graticule. Mask Editing The YT sheet mask editing features allow you to create new test masks for an instrument family by modifying existing masks or defining mask parameters from scratch. The copied mask retains the instrument settings that were part of the original mask. To edit an existing mask, or create a new mask based on an existing mask, simply drag and drop a mask from the Explorer view onto the YT sheet. WaveStar draws the mask on the graticule and shows existing line vertexes (points) as small squares, as shown in the following figure. NOTE. If a mask is visible on your YT sheet, and you copy or link the YT sheet to another data sheet, the mask data is copied along with the waveform data. To prevent this, clear the Show Mask checkbox in the toolbar before copying or linking the YT sheet data to other sheets. 4- 34 WaveStar Software User Manual
