The HD3G7 is a test signal generator that provides two outputs of a HD/3G-SDI video test signal. 720-line formats and 1080-line formats described in SMPTE standards are supported for both Level A and Level B mapping structures, including 4:4:4 and/or 12-bit sampling, Y’C’bC’r, R’G’B’, or XYZ color space, and 2K digital cinema formats. The 2×SMPTE 292M HD-SDI format used by some 3D TV applications is also supported.

The HD3G7 can generate up to 32 channels of 24-bit 48 kHz embedded audio, with independently set frequency and amplitude for each channel. The HD3G7 also has the ability to generate other types of ancillary data, such as video payload identifier, ancillary time code, and user-defined packets.

The HD3G7 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 up-convert an input 1.485 Gb/s HD-SDI signal to a 3G output. The HD3G7 has a clock/frame trigger output that can be used to synchronize the output with an oscilloscope, for example.
