Well put glaro. Why don't we see an all in one test device with useful functions like impedance with calculated watts for 70V systems, CAT 5 tester, Continuity, Wire distance calculator, Pink noise generator, Video generator with test patterns, etc. That would lighten up my tool kit considerably. Theres no info on what this device is outputing and inputing. Just to say video and audio inputs and outputs doesnt tell me s***. Are they test tones and patterns I can use? Composite video? Component video? RGB/VGA video? Low level audio out? Is this mic level, line level, speaker level? There is a lot of info missing. rickrood, Can you elaborate?
