ASE Question Of the Month

Which is correct?

You’re correct if you answered A!

An attenuator is a device placed in line with the scope’s lead to reduce the amount of voltage actually getting to the scope. For example, a 10:1 attenuator would convert a 100 volt input to 10 volts – thus protecting the scope from overload. “Sweep” is not typically a reference to voltage, but time – indicating the total time a signal is being displayed on the screen. For example, a scope set to 10 seconds per division and having 10 divisions on the screen would have a “sweep” of 100 seconds displayed.
