The ASTRODESIGN VA-1847-A is an HDMI 2.1 protocol analyzer designed for signal analysis, generation, and validation of HDMI source, sink, and repeater devices.

The analyzer supports both FRL (Fixed Rate Link) and TMDS signaling, including FRL operation with up to four lanes at 12 Gbps per lane. It can receive, generate, and analyze high-resolution HDMI signals including 8K/60p and 4K/120p timing.

Integrated protocol-analysis functions cover video and audio timing, InfoFrame, HDCP, SCDC, EDID, DDC, and CEC. Receiver, Generator, and Repeater modes allow the VA-1847-A to be used across HDMI development, interoperability evaluation, and compliance-pretest workflows.

HDMI 2.1 FRL & TMDS Analyze and generate HDMI 2.1 FRL signals up to 12 Gbps × 4 lanes as well as TMDS signals.
8K / 4K High-Frame-Rate Testing Supports HDMI timing up to 8K/60p and 4K/120p for advanced display and video-system evaluation.
Protocol Analysis Analyze InfoFrame, HDCP, SCDC, EDID, DDC, CEC, video, and audio information.
HDMI 2.1 CTS Pretest Supports HDMI 2.1 compliance-test pretesting during product development and validation.
