Who broke your oscilloscope? [Copy link]

Did you know? Among all the failures of test instruments, hardware problems account for less than 10%! Most of them are due to the lack of regular inspection and maintenance of the instrument and improper use of the oscilloscope, which leads to abnormal performance and requires repair or adjustment. Oscilloscope big data reveals the secret of how to make it "bright as new"!

The three killers of oscilloscopes

70% of oscilloscope board-level damage is caused by the test signal over-range, so please strictly comply with the signal input range requirements for the oscilloscope. Please note that for the oscilloscope test instrument, the channel direct input is usually divided into 50Ω and 1MΩ (especially 75Ω) to allow different input voltage signals. Please pay special attention to the two when connecting the probe.

Sometimes the static electricity can be as high as more than 10,000 volts. Static electricity discharge may cause instrument malfunction, may break down integrated circuits and precision electronic components, or cause component aging, and may even cause personal safety. In addition, static electricity can also cause static electricity attraction, dust adsorption, and contamination of integrated circuits and components.

It usually involves factors such as temperature, humidity, vibration, and altitude. For example, the operating temperature range of general instruments is 0-50 degrees. If the temperature is minus ten or twenty degrees, the instrument may not start normally or even freeze and crack the screen.
