Oscilloscope Setup

In this exercise you will use the Waveform Math menu to subtract one
waveform from another.
Set up an HP 8116A, or a signal generator capable of a 1 MHz,
as
squarewave, follows:
•
=
MODE NORM
•
FRO =
I MHz
•
=
DTY 50%
•
=
AMP
1.00 V
•
=
OFS 0.00 V
• =
Pulse squarewave
Connect the signal to a BNC tee on channel l using a 1 meter coaxial
cable . . Connect another 1 meter cable from the other side of the BNC tee
and terminate in 50 fl to channel 4.
The extra cable length between channels
between the signals on the oscilloscope. The propagation of a 1 meter
coaxial cable is approximately
the math function.
lbe following procedure will assist you in setting up the HP 5450lA for
optimal viewing.
