ePVGA Overview

The PVGA series of video test instruments from Advanced Testing Technologies, Inc. provides a comprehensive solution set for video generating and acquisition requirements in a UUT test environment.

The ENVID GEN-510 Enhanced Programmable Video Generator and Analyzer (ePVGA) is a fifth generation video instrument providing unparalleled coverage to new and legacy video requirements. As the successor to the legacy VID GEN-502 instrument, the ENVID GEN-510 has full backwards compatibility with existing 502 software applications and incorporates new and useful features.

The ePVGA is the world's only commercially available multi-format video generator and multi-format video acquisition device supporting RGB composite video (interlaced or progressive scan), stroke video (XYZ), mixed video (composite/raster and stroke interleaved), and rectilinear scan video (unmodulated or modulated). Captured video may be redisplayed on the host computer's monitor with the Video Redisplay Tool (ENVID GEN-510 Option 7), redisplayed in real-time on an external computer monitor (ENVID GEN-510 Option 4), or saved to a file for external analysis.

The first generation PVGA garnered multinational acceptance and is successfully supporting the B-1B, F-15, C-17, Eurofighter, T-50, and other diverse military platforms. The experience derived with these applications has been integrated into the next generation, the ePVGA. The ePVGA supports Composite Video generation, Stroke Video generation, Mixed Video generation, Secondary Composite Video Generation, NTSC Video/S-Video Generation, Component Video (YPbPr) generation, Raster Video Generation, and Video Acquisition. The ePVGA is also available with options such as hardware and/or software-based image acquisition video redisplay, Automatic Code Generation and DVI generation and capture. Included with the ePVGA are dual configuration (differential/single-ended) analog outputs and differential digital I/O.

As a self-sufficient instrument, the ePVGA represents a lower cost of ownership over a la carte generic instrumentation, such as arbitrary waveform generators, by eliminating the need for complex signal switching between instruments, integration of software interfaces from multiple vendors and the need for ancillary signal sources. Reduced nonrecurring development man-hours directly provide the benefit of shorter TPS development times and lower expenses. The Automatic Code Generation feature also supports the goal of shorter TPS development times.

With video instrument obsolescence issues arising, careful attention was given to supporting legacy CASS, ESTS, and RT-CASS video requirements, making the ePVGA an excellent replacement candidate. The availability of hardware-based acquisition redisplay and DVI digital video generation makes the ePVGA an excellent candidate for new state-of-the-art platforms such as eCASS and VDATS.

ePVGA Description

The ePVGA is a single slot C-sized VXI instrument supplied with a complete software library compatible with Microsoft Windows®. It integrates multiple video format/multiple output video generation for general purpose testing of military or commercial platforms. This configuration targets composite video generation, stroke video generation and mixed video generation (stroke over composite).

All video elements are capable of fully independent and simultaneous operation. The generator elements can be used separately to test single format video displays, or in combination to test mixed video format displays. Since all outputs are automatically aligned at run time, the ePVGA delivers high accuracy signals with no periodic maintenance.

Primary Composite Video (PCV)

The PCV generates high-resolution bit-mapped images for cathode ray tube (analog) and flat panel (parallel digital) displays. Standard and non-standard scan formats, are directly supported by the PCV. Two memory bitmaps (foreground and background overlay) support complex dynamic imagery. The background overlay may be superimposed on the main image. It can be updated from frame to frame as to content, position, or foreground/background status.

Stroke Generator (SG)

Unlike composite video, which is a scanned technology, stroke video utilizes direct point-to-point scanning with controlled slew rates. Due to its dynamic environment, the stroke video image is continually being modified for content, flashing indicators and updating aircraft or targeting positions. With the exception of very simple patterns, such as static crosshairs and basic geometric shapes, the construction of XYZ stroke video waveforms can be a demanding, time-intensive task that will overwhelm most generic waveform generators and test development schedules. The ePVGA's SG represents the most complete stroke video generator commercially available and is designed to support military stroke video avionics. Complex, interactive images can be produced by the SG by means of its patented programmable sequence control structure which manages the order, duration, and position of image elements.

Stroke Analog outputs

  • +/- 10 volts into 75 Ohms (single-ended)
  • +/- 20 volts into 75 Ohms (differential) with 12-bit resolution and 0.5% accuracy (local sense) and 0.2% (remote sense)

Secondary Video Source (SVS)

The SVS generates medium resolution bit-mapped images in any synchronized scan format. In addition, the SVS supports NTSC and PAL video to support commercial broadcast-type video. The purpose of the SVS is to produce a second video signal of either identical or different format than that of the PCV. The two video signals PCV and SVS - can be used together (master/slave configuration) to test multi-scan monitors, video switching systems, channel isolation et al., or separately to simultaneously test multiple displays.
