Q1: Can an oscilloscope measure DC voltage?
A1: DC voltage can be measured using either an oscilloscope or a digital multimeter. Each piece of testing equipment has its advantages and disadvantages.
Q2: What is the maximum frequency for the oscilloscope?
A2: System bandwidth determines an oscilloscope's fundamental ability to measure an analog signal - the maximum frequency range that it can accurately measure. Entry-level scopes will often have a maximum bandwidth of 100 MHz. They can accurately (within 2%) show the amplitudes of sine-wave signals up to 20 MHz.
Q3: What is the record length for an oscilloscope?
A3: The record length, measured in points or samples, divided by the sample rate (in Samples/second) specifies the total time (in seconds) that is acquired. Example: With a record length of 1 M points and a sample rate of 250 MSa/sec, the oscilloscope will capture a signal of 4 msec in length.
Tips: What should I pay attention to when using a handheld oscilloscope?
The handheld oscilloscope is an instrumentation device that measures the distortion of waveforms in the testing and measurement of low-frequency and ultra-low-frequency standard waveforms and is commonly used in power systems and other occasions that require testing the purity of signal waveforms.
- Thermal electronic instruments generally need to avoid frequent startup and shutdown, and the same is true for oscilloscopes.
- When making a quantitative measurement, the oscilloscope should be powered on and preheated for more than 10 minutes, so that the components in the machine work in a thermally stable state, otherwise the temperature of the components in the machine is in the process of rising, which will affect the measurement results.
- If you find that the waveform is disturbed by the outside world, you can ground the oscilloscope case.
