Murideo says it took them over 10 years to develop their latest signal analyzer (that seems like a long time to me). The Murideo-Fresco SIX-A is for testing basic and complex switching solutions (including complete high bandwidth HDMI cable testing, HDBaseT and HDIP link testing up to 18 GBPS — including 8K SUHD, all HDR flavors, plus legacy sources like 480i/p).

• Test HDMI/DVI Cables up to 18GBps, full TMDS testing
