    • Quick Guide

    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 does the sampling rate mean for a digital oscilloscope?

    The sampling rate is an important index of a digital oscilloscope. The sampling rate is also called the digitization rate. It refers to the sampling time of analog input signal in unit time and is often expressed in MS/s. If the sampling rate is not enough, aliasing is prone to occur.

    If the oscilloscope's input signal is a 100KHz sine signal, the oscilloscope's display signal frequency is 50KHz. What's going on here? This is because the oscilloscope's sampling rate is too slow, resulting in aliasing. Aliasing is when the waveform frequency displayed on the screen is lower than the actual frequency of the signal, or the displayed waveform is unstable even if the trigger indicator on the oscilloscope is on.

    So, how do you determine if the waveform shown has been duplicated for a waveform of unknown frequency? The frequency parameters of the waveform can be changed rapidly by changing the sweep t/div to the faster time base. If it is, the waveform mixing has occurred. Or the swaying waveform stabilizes at a faster time base, indicating that the waveform alias has occurred. According to Nyquist, the sampling rate is at least 2 times higher than that of the signal high-frequency component, and it will not occur. For example, a 500MHz signal requires at least a 1GS/s sampling rate.
