THat sounds a bit careless about calibration.

RGB in maximum input level should be 714 mV p-p. WHat is yours?
What is input noise level during HBI?
4x frequency error?
etc etc.

Tony Stewart thanks for your replay.

yeah.... maximum input level is 700 mv - p-p
i must check frequency error

i have one question.... what is HBI ?

 

[Nigel Goodwin]

i have one question.... what is HBI ?

I would guess 'Horizontal Blanking Interval'?, presumably an American term? - I've never seen the abbreviation before.

 

[Majid soltani]

I would guess 'Horizontal Blanking Interval'?

Exactly correct ... thank you so much ... my problem solve with your help

all friend thank you for reply to my questions...

 

[Tony Stewart]

In the PAL television standard, the blanking level corresponds to the black level, whilst other standards, most notably NTSC, set the black level slightly above the blanking level on a 'pedestal'.

There is both a Horizontal and Vertical Blanking Interval.
