The TG-5000A Dual-Format HD-SDI Pattern Generator from Maxtron is a single-pattern test signal generator with embedded 16-channel voice IDs and audio tones. It has a switch to select between 1080i 59.94 (UP) and 720p 59.94 (DN) format of the HD-SDI output. The test pattern is the SMTPE RP-219 HDTV Color Bars, which was specifically chosen to expose system weaknesses and limitations. Overlaid over the test pattern is a traveling wizard that moves in a ping-pong fashion about the screen to help reveal dropped or repeated fields/frames, as well as frozen video. A circle overlay is added when the unit is in the 720p mode, to aid in checking for proper display aspect ratios.
The TG-5000A offers audio channel voice IDs and tone combinations for all 16 stereo channels allotted in the SD/HD-SDI specifications. When the voice IDs are enabled, they repeat a specific channel ID every 15 seconds, making it clear which audio channel is being monitored. Between the voice IDs, there are standard level audio tones for the right and left channels within each group.
This pattern generator has a toggle switch to turn the unit on and off. The green power LED confirms power to the unit and blinks rapidly when the unit is in the 1080i mode.
