4K/HD Test Signal Generator


Ready for a range of audio and video testing with 4K systems

Full range of test patterns, extensive outputs Test signal generator that generates 4K signal (3840 x 2160p, 4096 x 2160p). Distributes each of two lines (4K video) from quad-link 3G-SDI to two outputs, or two HD-SDI lines (HD video) to three outputs. Embeds 32-channel audio in 3G-SDI or 16-channel audio in HD-SDI output. Equipped with two outputs for MADI signals. Two lines independently configurable.

Versatile 4K output support

Can produce any combination of 3G-SDI (Level-A/B), Square Division (SQD)/2-Sample Interleave Division (2SI), and 3840 x 2160p/4196 x 2160p.

Video test patterns

Standard test patterns include color bars, ramp, steps, white, black, pathological, crosshatch, multiburst, and noise. Register up to 10 custom test patterns created via computer.

Colorimetry switching

Choose from ITU-R BT.2020 or ITU-R BT.709 for 4K testing (except for custom test patterns).

Test pattern scrolling

Scroll test patterns horizontally, vertically, or diagonally.

Character display

Display time codes or channel numbers on test patterns as needed.

Output frame frequency switching

Choose from 59.94 Hz or 50 Hz.

Audio test signals

Supports multiple formats.

Two-line output

One line (SG-1) for 4K and HD output is provided as standard. Able to support two-line output (SG-1, SG-2) with option. SG-1 and SG-2 independently configurable. 4K output can be distributed to two systems, and HD output to three.


Output can be synced to an external reference signal, with BB or tri-level sync available for each of the three output lines.

External control, SNMP monitoring

Control the unit via telnet, or monitor operation via SNMP.
