I'm using 5112 and 1411 to acqurie standard color bar and measure its frequency.The signal is composite,and the picture acquired is in the attachment.The configuration of the 5112 are: min sample rate:100M, numSamples:13000S.So the frequency I measured is 15.6kHz.
I'd like to know what the frequeny measured refers to .
If I config numSamples at a large number which it can include several fields or frames of the video signal,what the f is?
Is the picture in the attachment two lines of the singal?
And how do I measure Frame frequency ,Line frequency ,colour cubcarrier frequency? Do they just depend on the numSamples or sample rate?
So many questions
Thanks a lot!
