Correct Answer - Option 1 : sawtooth wave
The calibration signal, usually available from a CRO is the Sawtooth wave voltage.
Cathode-Ray Oscilloscope (CRO):
CRO is a very fast X-Y plotter that shows the input signal versus another signal or versus time.
Applications:
The CROs are used to analyze the waveforms, transient, phenomena, and other time-varying quantities from a very low-frequency range to the radio frequencies.
Time Base Generator:
-
It generates an output voltage or current waveform, which varies linearly with time.
- The horizontal velocity of a time base generator must be constant.
- The displayed signal should be varied with time.
- It makes the signal to sweep the beam horizontally across the screen.
- Then the displayed signal varies linearly with time.
-
Hence the voltage is called Sweep Voltage.
-
The Time Base Generators are called Sweep Circuits.
The time base signal in CRO is a Sawtooth signal.
