Comb-based optical frequency metrology and atom clocks have pushed the measurement of time and frequency to unprecedented precision in recent decades 1. The recently emerged miniature ...

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 ...

After an RF or microwave signal has been converted to an intermediate frequency (IF) and digitized, the type of signal processing you choose to apply determines what information is extracted from the ...

Tektronix has released new firmware for the 5 Series and 6 Series MSO mixed signal oscilloscopes that unlocks a new analysis tool called Spectrum View. A free upgrade (see URLs below), Spectrum View ...

Every electronic circuit has some noise and it can affect both analog and digital circuits. Some noise comes from outside interference while some comes from random factors such as thermal effects.
