1.1 GENERAL INFORMATION
1.1.1 System Overview
Welcome to the T-RAD Application Software. This software, when coupled with a Gentec-EO T-
RAD, provides the user with a versatile measurement system. There are multiple THz sensors
available for the system. When a sensor is mated to the USB module, and the software is started,
the module reads the sensor type, sensor calibration, sensor wavelength response, and configures
the hardware appropriately.
The Applications Software communicates with the host PC via a USB port. The system uses the
T-RAD Command Set to do this.
Data is sent to the host PC when the instrument has had its data gate turned on. The data is
sent to the application at 5Hz.
1.1.2 Specifications
The following specifications are based on a one-year calibration cycle, an operating temperature of 18 to
28ºC (64 to 82ºF) and a relative humidity not to exceed 80%.
