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?

  1. When observing and adjusting the bright spots on the screen, the brightness of the bright spots should be moderate and not too bright.
  2. The voltage of "Y input" should not be too high, so as not to damage the instrument, and it should not exceed 400V during large attenuation. 6. Before shutting down, turn the brightness adjustment knob to the end counterclockwise to reduce the brightness, and then turn off the power switch.

The handheld oscilloscope can transform invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena. Oscilloscopes use a narrow beam of high-speed electrons to strike a phosphor-coated screen to produce tiny spots of light. Under the action of the measured signal, the electron beam is like the tip of a pen, which can depict the change curve of the instantaneous value of the measured signal on the screen.
