Measurements
Oscilloscope (2)
- A timebase oscillator normally deflects the trace in the X direction
(horizontally) – measuring time; the speed of the timebase
is calibrated in fractions of a second
- On the face of the crt there is a marked graticule to allow X and Y (vertical)
displacement to be measured allowing amplitude (voltage, Y)
and frequency (period, X) respectively to be computed
- The Y amplifier plus the tube determine the bandwidth of the oscilloscope.
Input capacitance and input voltage may restrict uses
- A PC with appropriate ADC can be used as an oscilloscope
