Page 3: Introduction
PUBLIC INFORMATION Introduction The GPX2-EVA-KIT evaluation system is designed as a platform for a quick and easy start of evaluation of the TDC-GPX2 time-to-digital converter. The kit offers a graphical user interface for user-friendly configuration and extensive testing of the TDC-GPX2. For a proper use of the evaluation system, we strongly recommended to refer to the latest TDC-GPX2 datasheet. -
Page 4: Quick Start Guide
PUBLIC INFORMATION Quick Start Guide This section describes how to set up the GPX2-EVA-KIT, establish basic operation and make measurements quickly. Install the Software Please download the latest software for the kit from: Link: https://downloads.sciosense.com/tdc-gpx2/ It is crucial to install the software before connecting the evaluation kit to your computer. A default driver loading of your OS may interfere with correct installation. -
