Question

The slope and level detector circuit in a CRO has a delay of 100 ns. The start-stop sweep generator has a response time of 50 ns. In order to display correctly, a delay line of

• A. 150 ns has to be inserted into the y-channel.
• B. 150 ns has to be inserted into the x-channel.
• C. 150 ns has to be inserted into both x and y channels.
• D. 100 ns has to be inserted into both x and y channels.

Answer 1

The correct option is A 150 ns has to be inserted into the y-channel.

A delay line of 150 ns has to be inserted into the y-channel to get synchronous between sweep signal applied to x-plate and test signal applied to y-plate.
