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 handheld oscilloscope?
The handheld oscilloscope integrates the functions of a digital storage oscilloscope, digital multimeter and digital frequency meter. It is powered by a battery and has a graphic liquid crystal display. This design adopts embedded design technology, embeds core components such as a microcontroller, A/D converter, LCD controller into the system, and uses an embedded operating system, ASIC design technology, LCD graphic display technology, and digital signal processing technology, etc. A comprehensively designed embedded instrument system. The instrument is fully functional, small in size, light in weight, very convenient to carry and operate, and has high technical content and strong practicability.
