is there a change in video leakage with or without applying 0.5V DC bias?
I measured and saw a difference:
without bias: 2mV pk-pk
with bias: 300 mV pk-pk
the bias was applied using a 1.5V battery with voltage divider of 100 ohm and 200 ohm to achieve 0.5V bias. I used battery to have cleanest possible power supply.
I require the video leakage to be 2mV also with DC bias. is there any reason why I didn't get that?
Hi Eli,
I assume your query is resolved. Please feel free to contact us if you have any more queries.
Thanks

Hello,
Can you please comments on the following questions before I can come to a conclusion about the video feed through level when 0.5V DC bias is applied
Hello Naveen,
see below in red for answers to your questions:
Expecting your reply,
Eli
Sorry for the delayed response.
Can you please try to measure video feedthrough by leaving both RF1 and RF2 floating as in our test set up we leave both RF1 and RF2 floating and measure video feedthrough at RFC.
