1. Specification applies when the positive or negative pulse width is greater than 50 µs.
2. For frequency signals greater than 100 Hz, an additional 0.1% per 100 Hz is to be added.
Accuracy = 0.4% + ( frequency – 1 ) × 0.1%

3. The accuracy of pulse width could also be calculated as [0.4% + (frequency/100 – 1) × 0.1%]/frequency.
Rise/fall time is less than 25 s. Specifications are based on a resistive load.
