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 is a PC oscilloscope?
A PCO or a PC-based oscilloscope is a form of oscilloscope based on a special printed circuit board that could be an ISA card, a USB, or a Peripheral Component Interconnect (PCI) card. The popularity of PC-based oscilloscopes is primarily attributed to the prevalent use and affordability of both laptop and desktop computers. Unlike traditional oscilloscopes, which are stand-alone equipment, PC-based oscilloscopes are also transportable. The interface acquisition of the PCO depends on the application which requires more system capability. It can be a video game port — when low-frequency signal and sound are required- or a regular audio card.
