Are there math functions on an oscilloscope?
Virtually every digital storage oscilloscope has math functionality. This goes beyond the instrument’s ability to measure, quantify and display the many waveform parameters of a signal at the input, although those properties are important too. We’ll take them one at a time.
What is the bandwidth of a digital oscilloscope?
The digital approach means that the oscilloscope can display any frequency within its range with stability, brightness, and clarity. For repetitive signals, the bandwidth of the digital oscilloscope is a function of the analog bandwidth of the front-end components of the oscilloscope, commonly referred to as the –3 dB point.
How to evaluate an oscilloscope for your application?
An oscilloscope must have sufficient rise time to accurately capture the details of rapid transitions (Figure 46). Figure 46: Rise time characterization of a high-speed digital signal. To calculate the oscilloscope rise time required for your signal type, use this equation: Using this equation is similar to using the equation for bandwidth.
How do you use dual waveform math on an oscilloscope?
Dual Waveform Math, as its name suggests, requires two signals at the input. To access this fascinating function, power up the instrument and press Math. The menu appears at the bottom of the display. Press the soft key associated with Dual Waveform Math.
How is an oscilloscope used in a RC circuit?
This experiment will lead you through the steps on using an oscilloscope to measure the output of a DC power supply and the output of a function generator and then to utilize the oscilloscope to measure the time dependent properties of a simple RC circuit.
How do you measure time with an oscilloscope?
You can make time measurements using the horizontal scale of the oscilloscope. Time measurements include measuring the period and pulse width of pulses. Frequency is the reciprocal of the period, so once you know the period, the frequency is one divided by the period.
How to make a signal on an oscilloscope?
You will now use a function generator to produce a signal on the oscilloscope. In order to prepare the generator for use, preset the control as follows. Press the POWER button (orange button on the lower left side). Press the [1k] button on the top row of green buttons.
