| Measurement range |
Basic frequency 1 to 440 Hz, external clock type: 1 to 5 Hz, PLL type: 5 to 440 Hz
For fundamental from 45 Hz to 66 Hz, measurement is compliant with IEC61000-3-2 and MITI guidelines (constant measurement / fluctuating measurement), except no 2.5-minute fluctuating measurement or waveform decision function. |
| Measurement system |
PLL synchronization
For fundamental from 45 Hz to 66 Hz, fundamental frequency and PLL synchronizing frequency phase deviation no more than 0.01% |
| Analysis method |
FFT |
| Type of window |
