RTScope ActiveX Control - Version 8.0 Provides functionality required to display signal data as either a Oscilloscope or Spectrum Analyzer style display. The Oscilloscope display will provide positive/negative signal amplitude displayed over a preset number of units (time), while the Spectrum display will provide signal strength displayed over a preset number of units (frequency). Signal data can be scaled in the vertical and horizontal axes allowing a complete signal sample to be displayed in as few as two data points. The control supports display of two separate signals when in Oscilloscope mode. In addition there are horizontal & vertical marker bars provided. These bars are mouse ‘drag able’ and provide feedback to the parent program as to their position in relation to the displayed signal. The RTScope OCX fires an Event providing the position of the vertical and horizontal marker bars.
