    • 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: How does a digital storage oscilloscope measure voltage?

    The oscilloscope can measure the voltage amplitude of various waveforms. It can measure both DC voltage and sinusoidal voltage as well as the amplitude of pulsed or non-sinusoidal voltages. What is more useful is that it can measure the voltage amplitude of each part of a pulse voltage waveform, such as the amount of impulse or the decrease in the top. The comparative measurement method uses a known standard voltage waveform to compare with the measured voltage waveform to obtain the measured voltage value.

    The measured voltage Vx is input to the oscilloscope's Y-axis channel, adjust the sensitivity of the Y-axis, select the switch "V/div" and its fine adjustment knob, so that the screen displays a convenient measurement height Hx and make records, and “V/div” switch and the fine adjustment knob position remains unchanged. Remove the voltage under test, input a known adjustable standard voltage Vs into the Y-axis, and adjust the output amplitude of the standard voltage so that it shows the same amplitude as the measured voltage. At this point, the standard voltage output amplitude is equal to the measured voltage amplitude. The comparison method measures the voltage to avoid vertical system errors and errors, thereby improving the measurement accuracy.

    Great 20 MHz digital oscilloscope
    I wanted a truly portable setup digital oscilloscope to help configure a DIY hearing aid inductive loop audio system at a relations home - for this, it is simply superb. Very easy to use, and gave good results when compared to my other bench oscilloscopes so highly recommended it.
