System bandwidth,

Bandwidth ↔ rise time
## Wire and winding calculations:

## 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/BW1^{2}) + (1/BW2^{2})
BW1 = 1 / √

(1/System BW^{2}) - (1/BW2^{2})
### Enter any 2 values, the 3rd one will be calculated:

## Some common probe and oscilloscope bandwidth values:

### 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.
