Input amplitude ranges according to above.
0.1 Hz – 100 kHz
0.1 Hz – 20 kHz
40-60%
Exceeding above duty-cycle limits may cause inaccurate readings.
72 MHz

± 0.02 % (typ) up to 15 kHz
± 0.50 % (typ) up to 100 kHz
± 0.50 % (typ) up to 15 kHz
Input jitter (pulse time variations) will affect accuracy, especially at high frequencies. Averaging may be
used to increase accuracy.
