Visual Test System - An Architecture You Can Count On . . .

The VTS offers the broadest and most powerful capabilities available for PC-based data acquisition, processing, distribution, display, and archiving. The system can acquire data from multiple instances of multiple inputs, such as PCM, time, analog, digital, MIL-STD-1553, and serial data. All data instances can be processed in real time, displayed in user-defined windows, archived, and output as PCM, time, analog, digital, 1553, and serial data. Designed for your enterprise, the VTS architecture embraces a true client/server model where data can be distributed over standard LANs to other VTS systems for archiving, processing, distribution, and display.

Heartbeat Display
VTS Screen Shots
The Heartbeat display sits at the top of the VTS Software applications tree, showing each VTS hardware and software module as well as module status. A convenient launching point for all VTS functions, the display is unique to your software and hardware configuration and can be easily extended to launch and monitor your own applications.

Dynamic Displays
Display real-time data in your choice of bar charts, cross plots, dials, range charts, strip charts, tables, and text. Each display type allows you to configure such properties as size, color, line thickness, update rates, units, three-limit bands, grids, and bitmap backgrounds. You can create unique displays and elaborate models of vehicle configurations, cockpits, views, and processes. Displays are created and modified in real time without intermediate steps and maintain the look and feel of other Windows applications. In fact, as standard Microsoft COM objects, VTS displays can easily be copied and embedded into other applications for reporting and presenting data.

Project-Oriented Database
To get you up and running faster, the VTS lets you load project files and resume operation in exactly the same state as you left it. A single command saves all files connected with VTS operation, including display definitions, parameters, processing, data distribution, and hardware setup. To modify a previous test, make your changes and save the project under a new name. Need to duplicate the original project’s test? Simply reload it and start.

Processed/Derived Parameters
The VTS Software processes all or selected data in real time. A drag-and-drop GUI easily defines complex algorithms chosen from a palette of over 25 functions, which can be expanded with C++ algorithms you develop yourself. You can extract all MIL-STD-1553 bus data and parameters encoded in a PCM stream according to the IRIG Standard 106, Chapter 8. What’s more, you can direct processed data to any of the system’s real-time displays, archive the data, send the data to the Analog & Digital Ports module, or distribute the data over your LAN.

Data Archiver
Archive raw and/or processed data from all sources at rates limited only by your storage hardware. Data is stored in well-documented formats for direct use by your applications, or data can be exported directly to ASCII. A virtual “tape deck” control panel provides an easy-to-use interface for recording and playback functions. System or IRIG time is embedded in each data block for direct file access to specific data for playback. For visual analysis or speed, archived data can be played back from 1/32nd to 8 times real time.

Software Development Kit
Your applications can access the Visual Test System through the Software Development Kit (SDK) to interact with the VTS, obtain status, manipulate the setup database, and define VTS data destined for the network, archiving, and real-time processing.

Client/Server or Standalone
The VTS can be configured as a traditional standalone system or as a client/server architecture system with I/O modules on the server and totally independent display, processing, and archiving functions on client PCs.

Wide Array of I/O Options
Configure your VTS with an array of I/O modules, including telemetry receivers, transmitters, bit synchronizers, decommutators, and simulators; IRIG time I/O, analog I/O, digital I/O, serial I/O, MIL-STD-1553 I/O, and ARINC 429; plus all the standard PC I/O interfaces.

Software-Reconfigurable Hardware
When you download new VTS software, you reconfigure hardware functionality — automatically. That’s because VTS hardware modules make extensive use of Field Programmable Logic Array (FPLA) technology. FPLAs or Programmable Logic Devices (PLDs) are software-configurable integrated circuits consisting of hundreds of thousands of gates and thousands of bits of memory.

Take, for example, the system’s single-slot Multifunction PCI Telemetry I/O module (MFT735-PCI). Without mezzanines, the MFT735 replaces the functions of four PCI or ISA boards, allowing you to support larger telemetry applications in your standard PC workstation or server. In just seconds, you can download software to change from four decoms to two bit syncs and two decoms, and so on. What’s more, as we add features to the MFT735, all you’ll need is a software upgrade to keep your system up to date.

Highly Configurable Decoms
VTS decommutators are highly configurable to handle special requirements beyond standard IRIG formats (e.g., being able to support variable frame lengths found in “Burst Mode” or “Pass All Mode” to capture encrypted data and to then encode the data later for decryption before commutation). Architected for flexibility, these decoms are capable of total hardware decommutation for very large frames, up to 128K words or more, with data frames sorted by parameter for display and archiving efficiency or by tag-data format for applications requiring data before receipt of an entire frame. Time can be inserted for every frame or subframe to a resolution of 1 microsecond. In addition, delta time is attached to every word to ensure accuracy for archiving and playback.

Simulator/Encoder
Encode PCM streams and simulate MIL-STD-1553 bus traffic from the graphical user interface or from data files. Or use independent PCM simulators to validate system setup using a combination of static values and trigonometric functions. Setup is quick and easy because it is based on your decommutator’s database.

Analog & Digital Output
Real-time high-rate telemetry data can be sent directly to the Analog & Digital Ports module in raw or processed format using 1st- to 6th-order EU conversions. A single module can receive high-speed data from all streams on the same Multifunction Telemetry module. Data from other sources, including processed parameters, parameterized MIL-STD-1553 data, and analog input, is directed to the module via the PC’s bus.

Built-In Performance
VTS modules are designed to maximize the system’s PC architecture, while adhering to industry standards. PCI boards are plug-and-play to ease installation, and they utilize one or more DMA engines to transfer data without devouring processor cycles.
