12G Test Signal Generator


Ready for a range of audio and 4K video testing of 12G-SDI systems

Test signal generator that generates 4K signals (UHD 3840 x 2160p, Full 4K 4096 x 2160p). 4K video signals that are output at 60p/59.94p/50p can be distributed from 12G-SDI lines to eight outputs and Quad Link 3G-SDI lines to two outputs at the same time. Embeds 16-channel audio into 12G/3G-SDI or 3G/HD-SDI output. Equipped with two outputs for MADI signals.

Versatile 4K output support

Can produce any combination of Square Division (SQD)/ 2-Sample Interleave (2SI) signals, and 3840 x 2160p/4196 x 2160p resolution. (12G mode can be used only with 2SI.)

Video test patterns/Flash function

Standard test patterns include color bars, ramp, step, white, black, pathological, crosshatch, multi-burst, and noise. Up to 10 custom register test patterns are created using a PC interface. Flash function allows White or Black signals to be inserted into video.

HDR/Resolution test chart

PQ and HLG (Gray scale, Color bar) test charts and ZONE Mono-scope resolution test chart are available as optional accessories.

Payload ID editing

Specify the color space and bit depth of HDR information in the payload of included or custom patterns. Four-byte payload data of your choice can also be specified.

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.

Colorimetry switching

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

Test pattern scrolling

Scroll test patterns can be selected horizontally, vertically, horizontally and vertically at the same time, sequenced, or randomized.

Character display

Display time codes or channel numbers on test patterns as needed.Alphanumeric characters able to be scrolled.


Logos(PNG format) created on a PC can be displayed on test patterns, and scrolled (excluding USER patterns).

Audio test signals

Outputs standard test signals (1 kHz, etc.) Test signals can also be customized by registering 10 computer-generated WAV (linear PCM) files (30 seconds, 32 channels).

External control, SNMP monitoring

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