DEAR ALL :
I am a junior Engineer , I produce some video signal ,like :
1.Vpp 700mV RGB analog output
2.LVDS output
3.TMDS output
4.NTSC/PAL TV Signal

So I have question , How to verify my output quality is OK? Should I use what kind instrument to measure ?
Like 1 and 4 are Analog , is thers any rule when PCB layout ?
2 and 3 are High Speed low voltage , seems the normal scope can not show its waveform , how can I guarantee my Signal Quality ?

Hope give me suggestions , Very thanks ~
 

Hi,
You need to give a test input of know parameters and expect an output that is also known. It should be easily measureable ( the input amplidue/phase difference should be adjusted) Once calibrated you can assume it is correct,
There are different measureing equipments needed.
