Data acquisition equipment supplier Heim Data Systems is debuting a compact (7.5-by-4.5-by-10-inch) signal acquisition system replete with advanced recorder functions. The company's new D7000 offers adaptable signal interfacing and interchangeable media cartridges, all in a compact package. Weight is about 22lbs. in a typical system configuration.

With a ruggedized mechanical design suitable for use in harsh environments, the external dimensions and configurable connector interfaces of the D7000 are designed to support direct replacement of legacy video and data recorders.

Front-panel connectors
The D7000's military-style connectors are all front mounted. They can be supplied in a generic configuration or with specific custom connector types and pin-outs.

The D7000 also features an additional power connector, so the unit can be powered from ground support equipment without disturbing flight power connector cables in aircraft applications. This enables direct form-fit replacement of both legacy video recorder and avionics data acquisition systems.

The system is also compatible with both the Heim Data format and the IRIG106 Chapter 10 standard, including a compliant IEEE-1394b data download interface on the media cartridge.

With up to 256Mbps total system data rate, Heim's latest recording/reproducing system uses interchangeable media cartridges, letting you choose and load either rugged hard-drive or flash-based solid-state media. The system's sealed hard drives are designed for high altitude missions and have built-in vibration and shock protection. The system's solid-state drives feature a secure erase function and have automatic wear leveling with bad block management to ensure high reliability.

The system's packet recording system also ensures accurate data time-tagging and consistent channel-to-channel phase relationships. The recording system ensures data time-tagging with 100ns resolution.

The D7000 mainframe also has Gigabit Ethernet data download capability. What's more, its SCSI media interface provides a high-speed output to other Heim data download and analog replay systems fitted with media cartridge receivers.

High accuracy time tagging
With its integral IRIG time code generator, the D7000 Series can also synchronize to external IRIG and GPS time sources. That feature supports sustained high accuracy time tagging of recorded data.

A D7000 can also be optionally fitted with an integral GPS receiver. With that option the system integrates time reception, distribution, and data time-tagging into a single package. The media cartridge can also be fitted with an integrated clock that permits laboratory-based time references to be automatically transferred to the recorder each time a cartridge is loaded.

In use, the system's mainframe holds up to four signal interface cards in any combination, providing a selection of interfacing, including concurrent recording of video, PCM, and MIL-STD-1553-bus sourcesall in a single unit. You also have permanent access to configuration and control functions through front panel controls, backed up by remote control available through integral serial, network, and discrete contact interfaces.

It does Windows

In operation, you can download your data to Windows 95, Windows 98, Windows 2000, Windows XP, and Windows NT platforms, in raw media format, ASCII, binary, or industry-standard file formats. Data upload and replay is possible from archived files. Heim also offers custom software for this system, and an applications driver library free to developers.
