Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...

Oscilloscopes are handy at measuring digital signals as well. Many oscilloscope measurements are used for characterizing pulse signals or digital data. While you can always use cursors or estimate the ...

What do you need to measure? Check out some of the common — and not-so-common —measurements that you can perform using a digital oscilloscope. The oscilloscope has morphed into a versatile and ...

14-bit analog-to-digital converter (ADC) oscilloscope delivers four times the signal resolution and half the noise floor of other general-purpose oscilloscopes Instrument built from the ground up with ...

When you’re hunting for a signal with your oscilloscope, the stronger it is, the better. If it’s weak, you might struggle to tease it out from other interference, or even from the noise floor itself.

The Series 7 DPO oscilloscope from Tektronix is the company’s first new high-end model in years. It uses an optical port to ...
