SM22: NTSC / PAL / 960H / aCVi Video Test Pattern generator

SM22 is a broadcast quality NTSC / PAL / 960H / aCVi video test pattern generator.

aCVi is a SingMai proprietary video interface for transmitting SD and HD video over long distances of coaxial or twisted pair cable.

SM22 generates 24 different patterns (including a zone plate) for 16 SD and HD video standards. White noise and hum may be added to the video output. It is controlled by a simple rotary control and switch with status provided by a 128 x 32 OLED daylight readable display.

SM22 is easy to operate, affordable and compact, and can run on its own internal batteries for up to 4 hours.

It is perfect for the evaluation and measurement of SD and HD video products and systems in industries such as security (CCTV), industrial inspection and broadcast TV.

Inputs: 5VDC power (100-260VAC adaptor supplied). Internal NiMh batteries allow up to 4 hours of continuous operation.

Dimensions: 120 x 78 x 27mm.

Outputs: CVBS, aCVi (BNC).

Standards: NTSC-M, PAL, PAL-M, PAL-N, 960H-NTSC, 960H-PAL, aCVi - [720p-25/30/50/59.94/60Hz, 1080p-24/25/29.97/30/50/59.94/60Hz, 1080i-50/59.94/60Hz].

Patterns available include: 75%/100%/SMPTE Colour bars; 50% grey, 100% white, red, green, blue flat fields; 2T/30T and Pulse bar, Modulated ramp, 5 step linearity, 30MHz Multiburst, 30/15MHz luma/chroma sweep, Crosshatch, Bounce, Circular zone plate, CCIR-17/18/330/331, N7CMPF, N7CMBF.

VITS insertion (CVBS output).

Programmable amplitude white noise and hum may be added to the video output.
