Know Your Device Well: Reasons for Common Oscilloscope Problems
An oscilloscope is a device that we use in different fields; to handle it properly, you must know all about this device. There can be some possible reasons for common oscilloscope problems that we are going to discuss here in this article.
Not just for the electrical engineer’s such devices are useful, but many of the different fields these are used, and there are many tools in the line when it comes to the measuring and testing device. Electrical measuring instruments should be taken care of properly to make them active for long and long.
Here are some of the common oscilloscope problems:
• When Horizontal waveform is not Shown:
Trigger selective switch in the oscilloscope is turned to outside, and no external signal is input. Because of which there is no sawtooth wave. The problem here to note down is level knob doesn’t adjust properly, and the stability potentiometer doesn’t adjust to the critical state, which enables the scanning circuit to be triggered.
No external signal is input to the socket as the X-axis selection is wrongly put on the external position. For the two-channel oscilloscope, when the channel is used, and the trigger switch is pulled to the location of YB, then no STW will be there.
• No Spot or Wave Shape:
When power isn’t connected, and the brightness knob isn’t adjusted well, and the shift knob of the X and Y axis is at a slanting position. These can be the reasons of oscilloscope problems. The balance potentiometer of the Y-axis isn’t adjusted correctly, which causes an imbalance in the DC amplifier.
• Unstable Wave:
Scanning circuit under a self-excitation scanning status but not a critical state to be triggered, and this is because of stability potentiometer is over-rotated clock wisely. When you don’t select the correct level of the trigger coupling according to the different signal frequency or when the high-frequency trigger state is selected, then the trigger selector switch is mistakenly placed outside the file. Sometimes scanning under the automatic transmission is the reason where the oscilloscope display instable wave.
• Vertical Waveform Is Invisible:
There can be various reasons like input DC coupling ground AC switch was wrongly put in ground position. The high and the low potential ends of the input area at the anti-termination of that of the circuit, and another reason can be when the input signal is too small, and the V/div is wrongly pulled to low sensitivity level.
• AM waveform disorder:
When T/div switch is improperly selected, which results in incorrect scanning frequency, which is chosen according to the amplitude selection frequency but not the audio amplitude modulation signal frequency?
When the operator doesn’t know the principles of oscilloscope and oscilloscopes panel, they can encounter many problems. It can be a great help identifying all about the possible reasons for oscilloscope problems. Oscilloscope, which is a crucial tool in electrical engineering, but when used by the non-professionals, they are advised first to gain knowledge about these electrical measuring instruments to make their proper use.
