Duty Cycle [2][4][5] | 0.39% – 99.60% | ± 0.398% of full scale [3] | |
Pulse Width [2][4][6] | 1/Frequency | 0.2 ms + (range/256) | |
Amplitude | Fixed 0 to + 2.8 V | ± 0.2 V |
Notes for square wave output specifications:
1Output impedance: 3.5 kW maximum.
2The positive or negative pulse width must be greater than 50 µs for adjusting the duty cycle or the pulse width under different frequencies. Otherwise the accuracy and the range will be different from the definition.
3For signal frequencies greater than 1 kHz, add 0.1% per kHz to the accuracy.
4The accuracy for duty cycle and pulse width is based on a 5 V square wave input without dividing signal.
5Duty cycle can be set for 256 steps and each step is 0.390625% per kHz.
6The pulse width can be set for 256 steps and each step is 1/(256 x Frequency).
