Qseven® Reference Carrier Board
Q7-BASE
Carrier Board
Qseven is a Computer-on-Module (COM) standard for small sized and highly integrated systems adopted by SGET. The Qseven concept is an off-the-shelf, multi-vendor, Computer-on-Module that integrates all the core components of a common PC and is mounted onto an application specific carrier board. Qseven modules have a standardized form factor of 70 mm x 70 mm or 40 mm x 70 mm and have specified pinouts based on the high-speed MXM connector, regardless of the vendor. The Qseven module provides the functional requirements for an embedded application, which include, but are not limited to, graphics, audio, mass storage, network and multiple USB ports. A single ruggedized 230 pin MXM connector provides the carrier board interface to carry all the I/O signals to and from the Qseven module. This MXM connector is a well-known and proven high-speed signal interface connector that is commonly used for -PCI Express graphics cards in notebooks.

AC Power Sources, Frequency Converter
MAC-01, -02, -03
-
For reliability, all models of the Titan AC Power Sources/Frequency Converters are fully current limit protected against either continuous or transient short circuit or overload conditions. When an overcurrent condition exists, the internal current control loop overrides the voltage control loop and scales back the sinewave drive until it sees a safe output current level.

Emissions Reference Source (ERS)
Emissions
-
The ERS is a comb generator that radiates RF continuously every 2MHz over the range 30MHz - 1000MHz. Each 2MHz peak is precisely measured during the calibration process with the ERS orientated both vertically and horizontally. These measurements are correlated against a 3m OATS such that any fully implemented CISPR16 site, measuring at 3m and using height scanning, will read the same.
