System bandwidth calculator

Online calculator for formulas used in electronic circuit design and electrical engineering.

Basic electric calculations:

Ohm's Law, Ohm's Law with power, DC power, AC real power, LC resonant frequency, Capacitor charging/discharging, Capacitive reactance, Capacitive current + reactive power, Capacitor energy, Capacitor Δ energy, RC discharging, Inductor square pulse, Inductive reactance, Inductive current + reactive power, Inductor energy, 2 parallel resistors, 3 parallel resistors, System bandwidth, Bandwidth ↔ rise time

Wire and winding calculations:

Diameter ↔ cross section ↔ AWG, Wire resistance, Wire weight, Current density, Wire R thermal drift

Calculate System bandwidth: 200MHz, 150MHz, MHz


This can calculate the system bandwidth (BW) of two cascaded stages. You can use it for example to calculate the system bandwidth of your probe and oscilloscope, knowing your oscilloscope bandwidth and the probe's bandwidth. You can also calculate what BW the probe has to have to achieve a certain system BW knowing the scope BW.
     System BW = 1 / √ (1/BW12) + (1/BW22              BW1 = 1 / √ (1/System BW2) - (1/BW22

Enter any 2 values, the 3rd one will be calculated:

BW1 (probe): -0.1 +0.1 -1 +1 -10 +10 -100 +100
BW2 (scope): -0.1 +0.1 -1 +1 -10 +10 -100 +100
System BW: -0.1 +0.1 -1 +1 -10 +10 -100 +100

System bandwidth formula says:

•The system bandwidth of a 200MHz (two hundred megahertz) probe and a 150MHz (one hundred and fifty megahertz) oscilloscope is 120MHz (one hundred and twenty megahertz).
•If the bandwidth values of two cascaded stages are 200MHz (two hundred megahertz) and 150MHz (one hundred and fifty megahertz), the system bandwidth is 120MHz (one hundred and twenty megahertz).
•A 150MHz (one hundred and fifty megahertz) oscilloscope needs a 200MHz (two hundred megahertz) probe to achieve a 120MHz (one hundred and twenty megahertz) system bandwidth.
