Page 9: Smoothing And Filtering
VB2SX20SPS User Guide Smoothing and Filtering Velocity: The VBSSX20SPS has three smoothing settings (Dynamic Modes) for velocity: High Dynamics, Normal and Low Dynamics. High dynamics has the least amount of smoothing and must be used for high dynamic tests where Time or Distance measurements are critical to the test, such as Brake stop and acceleration tests. -
Page 10: Gps Antenna
VB2SX20SPS User Guide GPS Antenna The GPS Antenna supplied with the VB2SX20SPS is a 3.5v active antenna. For the best possible signal quality, it is important to maintain a clean connection between the antenna and the VBOX. Before fixing the antenna to the VBOX, ensure that there are no dust particles in either connector. - Page 11 VB2SX20SPS User Guide Digital and Analogue Outputs The digital outputs on connectors OUT1 and OUT2 are a frequency/pulse output corresponding to velocity, long ACC or Lat ACC. The frequency range is adjustable in software or via the front panel controls.
- Page 12 VB2SX20SPS User Guide Digital Inputs The DIGITAL I/O socket contains the two digital inputs for the VB2SX20SPS. Digital input 1 is also referred to as the Brake trigger input. This input is connected to an internal timer capture module that is able to record precisely an event time for use in brake distance calculation. This period of time is called the trigger event time, and is given as the value in milliseconds between the trigger event and the last GPS sample.
