# Question 1.1
|
|
What happens to the Direct output signal if the terminator is not connected to the attenuated output of the pulser?
|
|
A: To start, time scale is 400 microseconds, delta of 1.4V
|
|
attenuatrion switches
|
|
normal operating shape is exponential decay after an impulse. 4V
|
|
Now, removing attenuatrion plug. No change
|
|
Removing the plug on the cable connected to oscilloscope, doubled magnitude of signal
|
|
The only thing that changes is the slope of the pulse decay. Is also dependent on attenuation. No impedence on the attenuated port results in less severse slope
|
|
This is a result of the impedence on the attenuated side. If all attenuation is on, it is effectively very high impedence just like the oscilloscope. No attenuation is low impedence, and therefore it isn't matched
