4K/HD Test Signal Generator


Test signal generator that generates 4K signals (UHD 3840 x 2160p, Full 4K 4096 x 2160p). Also produces HD video signals (3G/HD-SDI). Two internal lines of signal sources, which can be configured separately, are available as an option. Also enables payload ID editing. Specify color space and HDR information in payload ID, according to included or custom patterns.


ESG-4000 (BTO Product):

  • Supports 3G/HD-SDI output.

  • 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.

  • Two outputs for MADI signals


  • Supports 12G/6G(optional)/3G/HD-SDI output.

  • 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.

  • Two outputs for MADI signals


  • Supports 12G/6G(optional)/3G/HD-SDI, IP output.

  • Video-over-IP interface supports SMPTE 2022-6. (SMPTE 2110 will also be supported.)

  • 4K video signals that are output at 60p/59.94p/50p can be distributed from 12G-SDI lines to four outputs and Video over IP interface to two outputs.

  • Embeds 16-channel audio into 12G/3G-SDI or 3G/HD-SDI output.

Versatile 4K output support

Can produce any combination of 3G-SDI(Level-A/B), Square Division (SQD)/ 2-Sample Interleave (2SI) signals, and 3840 x 2160p/4096 x 2160p resolution. (*Only ESG-4100/4200 support 12G-SDI. 12G mode can only be used with 2SI.)

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.

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 created via PC interface. Flash function allows White or Black signals to be inserted into video.

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

Scrolling 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 necessary. 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.


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