2. Scope2
A scope is a device that has measures the voltage across its
input at a fixed rate. The scopes you will be using take a
voltage measurement every ns s, which it stores in its memory
(has room for 2500 measurements). It stores it with 8 bits of
precision (1/28
=0.004). It then makes a graph of voltage versus
time. The graph is refreshed whenever it receives a “trigger”.
You set how which measurements it should display relative to
the trigger time.
The trigger is a condition you set on a signal fed into the signal
input. When the signal satisfies the conditions, the display is
refreshed. Often, you feed the same signal into the display input
and the trigger input, but not always (you’ll see tomorrow an
example of when you would want different inputs).

7. Practice Signal Source7
We’ll use a “signal generator” to make some voltages that vary
with time, and then measure them using the oscilloscope, to
prepare for tomorrow, when we’ll measure the signals from
muons. “Coaxial cable” will take the “source” to the Scope.
