Use of a PC-Based Digitzer in a Medical Acoustic Microscopy System By Andrew Dawson, Ph. D-GaGe (a Vitrek brand) Introduction ABSTRACT: Construction of a medical acoustic microscopy system is discussed with focus upon usage of a PC-based high-performance GaGe RazorMax digitizer. Three main aspects of the RazorMax’s operation are addressed: usage of Dynamic Range Expansion (DRE) to maximize the detectability of small ultrasonic echoes, high-speed PCI Express Data Streaming for the fastest scanning speed and usage of GaGe’s Trigger Out signal for efficient and synchronous ultrasonic triggering. Conventional ultrasonic imaging [...]

Ground-Breaking Lightning Study Uses GaGe Razor Express High-Speed Digitizer By Gerald Allgaier, GaGe (a Vitrek brand) Introduction Razor Express digitizer is an integral part of VHF broadband interferometer designed to investigate high-energy radiation from lightning strikes and multi-stroke positive cloud-to-ground flashes. A doctoral dissertation published in 2022 by Michelle Urbani, a PhD candidate at the Universitat Politècnica de Catalunya BarcelonaTech describes the  development of a VHF broadband interferometer to investigate and better understand unsolved lightning phenomena [1]. Very high frequency (VHF) is the International Telecommunication Union (ITU) designation for radio [...]
