All Interfaces Output Independently
Independently developed by Shenzhen Yuanwei Technology Co., Ltd., covering all audio/video interfaces of a TV set. All channels are mutually independent, with format, image and audio set separately; HDMI channels support HDCP, EDID and CEC verification — an industrial-grade test signal source for production lines, labs and R&D departments.
One TV / one mainboard needs only one AG-681P for testing — a cleaner bench layout
Each channel’s format, image, audio and other parameters can be set independently; all channels output differently during testing, providing greater flexibility for production testing.
2 HDMI 2.0 channels output up to 4K2K YUV420 60Hz with HDCP 1.4 / HDCP 2.2 verification; 1 HDMI 1.4 channel supports normal and full verification modes; all 3 support EDID and CEC testing, with results shown directly on the output screen via OSD.
The 3 HDMI channels support dynamic image playback in 1080P25 / 1080P30 / 1080P50 / 1080P60 formats, meeting moving-picture test needs.
All channels support looped auto-play of up to 8 images, with per-image duration settings and manual switching — ideal for aging and full-inspection stations.
100Hz–20KHz sine wave (0.1KHz steps) for FCT testing, sweep tone for aging, plus WAV music playback — for manual testing and bass testing.
All interfaces have protection circuits, withstanding frequent plug/unplug testing; an RS232 interface with communication protocol enables integration with other automation equipment.

The front panel integrates a 4.5-inch color screen and silicone buttons; all signal interfaces are on the rear panel — tidy cabling and smooth operation.
The device uses a 4.5-inch color display, 9 silicone buttons and 5 arrow keys for all settings; an RS232 serial port with communication protocol enables PC remote control.
Color graphical interface with independent settings per channel; a clear menu structure that line staff can use without training.
Generated in real time by built-in algorithms with sharp edges and no compression artifacts, covering the test signals required by GB/T 50525-2010 "Code for Measurement of Video Display System Engineering".
Drawn in real time by built-in algorithms, not image playback — no jagged edges, no compression noise.
Covering color, geometry, sharpness, grayscale and all other display test items; the count keeps growing with customer needs — currently 57.
Dynamic image playback for checking motion blur, response time and moving-picture quality.
A 16G SD card is included for importing custom test patterns and music files.
7 independent audio channels corresponding to AV1, AV2, YPbPr, SCART, HDMI1, HDMI2, HDMI3; sample rate 48KHz, frequency 0.1KHz–20KHz in 0.1KHz steps.

| Item | AG-681P Multi-Format Signal Source | DVD Player |
|---|---|---|
| Professionalism | ✓Purpose-built for production-line testing: 8 independent signal outputs, built-in algorithmic professional test patterns | ✗Consumer-grade — only 1 output, quality depends on the disc |
| Test Stations | ✓One device serves multiple test stations at once, with no mutual interference between channels | ✗One DVD player per station — bulky and messy to manage |
| HDMI Testing | ✓3 HDMI channels, supporting 4K2K, HDCP 1.4/2.2 verification, EDID / CEC testing | ✗No HDCP verification — incapable of professional HDMI testing |
| Reliability | ✓Industrial-grade design with no wearing parts, running 24/7 continuously | ✗Laser heads and discs wear easily — high failure rate over long-term use |
| Technical Support | ✓Direct support from original-factory engineers; custom test patterns and functions on request | ✗No test-related technical support |
From TV mainboards to whole-set assembly, from automated testing to R&D verification — one device covers the entire display product testing process.
Every device is strictly calibrated to national standards before shipment, ensuring signal accuracy and consistency.
