Q & A

What is the function of the display panel on an oscilloscope?

The display panel on an oscilloscope is used to show the graphical representation of the measured signal. It contains the Y-axis for voltage and the X-axis for time, allowing users to observe signal behavior over time.

How does the Y-axis and X-axis on the oscilloscope work?

The Y-axis on the oscilloscope measures voltage, while the X-axis measures time. The Y-axis consists of 8 divisions, and the X-axis has 10 divisions, helping users analyze the amplitude and frequency of the signal.

What does the power button do on an oscilloscope?

The power button is used to turn the oscilloscope on or off. When the oscilloscope is powered on, the indicator light next to the button will illuminate.

How do you adjust the tilt of the frequency line on the oscilloscope?

The tilt of the frequency line can be adjusted using the press rotation knob. By rotating it, the frequency line can be made either more or less inclined relative to the X-axis.

What is the purpose of the focus knob on an oscilloscope?

The focus knob is used to adjust the sharpness or thickness of the frequency line. Users can make the line clearer or more defined as per their needs.

What does the intensity knob control on an oscilloscope?

The intensity knob adjusts the brightness of the frequency line on the oscilloscope. Users can increase or decrease the brightness to make the line more visible according to their preferences.

What are the vertical position controls used for?

The vertical position controls, which include separate knobs for Channel 1 and Channel 2, are used to adjust how the signal is displayed vertically on the screen.

How does the Volt/Div control work on an oscilloscope?

The Volt/Div control allows users to adjust the voltage scale for each division on the Y-axis. This helps in determining how much voltage each division on the graph represents.

What is the AC/DC switch used for on an oscilloscope?

The AC/DC switch allows users to select which part of the input signal they want to display. It can show only the AC signal or both AC and DC signals simultaneously.

Why is calibration necessary before using the oscilloscope, and how is it done?

Calibration is necessary to ensure accurate readings. It involves connecting the probe to Channel 1, setting the oscilloscope to the proper voltage scale, and adjusting the display to show the correct number of divisions that correspond to the known calibration voltage (e.g., 2 volts).
