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: Can an portable oscilloscope detect sound?

Using an oscilloscope and a microphone, sound waves or vibrations traveling through the air can be measured and viewed on an oscilloscope screen. The graph on the oscilloscope screen shows the intensity or amplitude of a sound on the vertical axis and time (how intensity changes with time) on the horizontal x-axis.
