Description

LYNX Technik has long been recognized for its feature-rich and user friendly multi-format test signal generators through its Testor series.
The greenMachine Testor constellation is the company's latest offering of test signal generators and is available for the greenMachine titan hardware and greenGUI software platform. greenMachine Testor is an ideal trouble-shooting A/V tool for technicians and engineers working in the field, in-studio applications and for line-up tasks in master control rooms. Anywhere there is an A/V testing, designing,
repairing and troubleshooting environment, the greenMachine Testor will be useful.

The greenMachine Testor constellation is a video and audio test signal generator that comes pre-configured for the greenMachine titan platform. It supports 12G (4K UHD), 3G, HD, SD-SDI formats and when operating in UHD mode, the Testor constellation can provide a single channel test generator. For 3G video formats (and below) the Testor constellation offers four independent test generators. To
summarize the two options, it is currently offered in two configurations:

1. Single Channel 4K/UHD (up to 3840 x 2160p) - 12Gbit/s SDI and quad link (2SI)
2. Four independent channels up to 3G SDI

Standard static and dynamic video test signals and patterns are included, and for added flexibility, users can upload their own user-defined signal patterns. Logos and text can also be added to the test signals, which is very useful for example for channel identification. The included collection of patterns supports all video standards up to 4K/UHD. User-defined pattern uploads can be resampled for other standards. The Testor constellation also offers test signals for various HDR standards (PQ, HLG, SLog3). Plus, the full collection of test signals can be shared with all greenMachine devices in a network (greenUniverse).

The integrated graphics editor provides a tool for users to place images & logos, add text, and even add user-defined signal patterns and graphics. All items can be moved and edited simply with a computer mouse. A scaler ensures users can scale test patterns to match the format.

The greenGUI software provides users with a true, advanced preview interface (including zoom) to check test signals in the GUI, control the outputs, format the settings, and manage customer-defined image and test pattern uploads. greenGUI software is free of charge and can be downloaded from here.

The greenMachine Testor also includes a 16-channel audio test generator with adjustable level, phase, frequency, mix-down and an EBU/AV sequence. All the audio measures are embedded into the SDI video or output to the external audio outputs of greenMachine. Through the audio crossbar all audio generator channels can be individually assigned to the embedder inputs and the external audio outputs (AES or analog). The timing of the audio and the video test signals including the output reference signal (Bi-level SD or Tri-Level HD) can be individually set in relation to an attached input reference signal.
