Signal Math (Oscilloscope & FFT)

Analytical tools required when working with an oscilloscope. Allows to calculate the required equipment Bandwidth based on the signal Rise Time using the formula BW = 0.35 / Tr, as well as calculate FFT spectral analysis parameters, such as Nyquist frequency and bin frequency resolution (Freq Resolution).

Rise Time ↔ Bandwidth

Measured Rise Time (in Nanoseconds)

Signal transition time from 10% to 90% amplitude.

Required Oscilloscope Bandwidth (BW)

233 MHz

For the oscilloscope to correctly measure this signal, its analog bandwidth must be at least 233 MHz.

FFT Parameters (Fast Fourier Transform)

Sample rate (MS/s)

Number of FFT points

Nyquist Frequency

5.00 MHz

Maximum frequency without aliasing.

Resolution (Freq Res)

9.77 kHz

One FFT bin covers this bandwidth.
