    TVL Measuring

    I really want to thank all the members that have replied to my subject. Back to the subject, it is well known that oscilloscopes and spectrum analysers will depict any analog signal covered by their measuring range, and will give much more information than the TVL. I heard about a device that is handy and portable that can give direct readings of TVL, but the side that provided me with this info is unreachable. It seems that it is a self designed circuit. Many thanks.
  3. Dear All, I need to know if there is any CCTV testing device that can measure the resolution or TVL of the camera, due to some exageration from some suppliers about their cameras' resolution and picture quality. Regards.
  4. Dear all, I would like to ask if there is in the market any CCTV test devices that measure the real TVL of any analog camera. Thanks in advance
