Question: How do you calculate the amount of time the Spectrum Time indicator (the orange bar) represents?
Answer: Spectrum Time = Window Factor / Resolution Bandwidth
- Window Factors:
| FFT Window | Factor | |
| Kaiser | 2.23 | |
| Rectangular | 0.89 | |
| Hamming | 1.30 | |
| Hanning | 1.44 | |
| Blackman-Harris | 1.90 | |
| Flat-Top | 3.77 |
- The Resolution Bandwidth can be found next to the RBW readout on the MDO4000 display.
