DG-4 Digital Pattern Generator

Model DG-4
Digital Pattern Generator

The DG4 is a full featured, multi-pattern, multi-format, SMPTE 259M (SD) and SMPTE 274M/296M (HD) SDI test pattern generator with 16-Channel voice ID’s and tones plus analog genlock input and analog black-burst output. The pattern lineup was specifically chosen to expose system weakness and limitations. The moving zoneplate is used to qualify video compression and scaling. The pathological pattern is used to stress the PLL’s in the signal path. There is even the traveling image which moves smoothly and randomly about the screen to reveal dropped or repeated frames. Also included is a white flash video pattern with coincident audio tone to measure the audio-to-video encoder delays. $

The embedded voice channel ID repeats every 15 seconds, leaving no doubts or confusion about what audio channel is being monitored. In between the voice ID’s are standard level 1kHz audio tones for the “right” and 440Hz audio tones for the “left” within each group. The dwell is approximately 1 sec of voice and 14 seconds of tone. The inclusion of standard level tones permits very accurate system leveling. The DG4 digital audio output level can be selected for the US -20dBFS or the European -18dBFS standard output level.

A genlock input can force the output of the DG4 to match the genlock source frame rate simplifying the format selection process. The DG4 also outputs an analog black reference, tri-level for HD, bi-level for SD, in the selected format providing the user the ability to generate a time adjustable reference signal.

The DG4 test pattern, format, and operational features are front panel selected using smart pushbuttons (function defined by mode) and displayed on an integrated 20x2 LCD display.

Power is supplied from external wall mounted 12VDC @ 1A universal power supply.
