Tektronix SD17 SD/HD/3G-SDI Test Signal Generator

The SDI7 is a test signal generator that provides two independent channels of SD/HD/3G-SDI video test signal generation in a variety of formats with 2 outputs for test and test/black signal generation per channel (3G-SDI signal generation is optionally available). The SDI7 can generate up to 32 channels of 24-bit 48kHz embedded audio, with independently set frequency and amplitude for each channel. The SDI7 also has the ability to generate other types of ancillary data, such as video payload identifier, ancillary time code and user-defined packets.The SDI7 includes a wide variety of standard test signals, including SMPTE color bars, pathological test patterns and a programmable moving zone plate pattern and it also has the ability to generate full frame test signals created by the user. AV timing signal generation, when used in conjunction with a waveform monitor, can be used to ensure that audio and video are synchronized through a video path. Circle, multi-language text and color logo overlays may be applied to the generated test signals to check aspect ratio, identify streams or apply station logos. The SDI7 has a clock/frame trigger output that can be used to trigger an oscilloscope to be synchronous with the video output.
