Beta SP input calibration issue Help Needed

[Chad Brewer]

Component color bars from what signal generator?
Did you verify that SG source has 7.5 IRE black before running through the VTR?
What does the waveform tell you when there is nothing going into the VTR?

this switch does not exist on a 2800. Tell me where your bar source comes from – tell me the model # of your waveform monitor. Where are you getting component bars from – a generator ? Or a Digi Beta VTR ? Every step of the way is important. Don’t leave anything out.

Thanks for the replies. Here is what I found.
I thought my deck was out of calibration but I had overlooked the 7.5 vs 0 ire setup switch on the AJA Kona. What I wonder is why would you want one vs the other?
I have never viewed the output of a analog deck and NOT had the 7.5 so why would you want the analog output to be at zero. zero is for 601 signal, or as I see also for component. So why would component analog need the choice? I have never had a component analog WF/VS all mine have been component digital and composite analog. I find that component monitoring should be zero, but beta SP input should be 7.5, then the output of the SP has the setup added and then the monitor is too bright…

hi dan

luckly enough i’m in PAL land.
what i understand from the books is that in Japan and some other country’s the analog pedestal of 7.5IRE is not used this is just a different standard.i geuss they found we didn’t had standard’s enough 😉

for a lot of info about analog videosignals look at this site

very in depth explaination of everything
