Measure EN The measurement display area can display up to 32 measurement parameters, and the measurement is carried out according to the selection order. If a 33rd measurement parameter is added, the first measurement parameter will be deleted. Note: If the parameter does not match the measurement condition, “ **** ” will be displayed. 10.2.1 Time parameters 1. Period: Defined as the time between the mid-threshold intersection of two continuous, homopolar edges. 2. Frequency: Defined as the reciprocal of the period. 3. Rising time: The time that the signal amplitude rises from the lower limit to the upper limit of the threshold. 4. Falling time:
The time that the signal amplitude decreases from the upper limit to the lower limit of the threshold. 5. Positive pulse width: The time difference between the threshold midpoint of the rising edge of the pulse and the threshold midpoint of the following falling edge. 6. Negative pulse width: The time difference between the threshold midpoint of the falling edge of the pulse and the threshold midpoint of the following rising edge. 7. Positive duty cycle: The ratio of positive pulse width to period. 8. Negative duty cycle: The ratio of negative pulse width to period. 9. Pulse width: Time from the first edge of the data source to the last edge. 10. Maximum time:
The time value corresponding to the maximum waveform (Vmax). 11. Minimum time: The time value corresponding to the minimum waveform (Vmin). Note: The upper threshold, middle threshold and lower threshold are 90%, 50% and 10% respectively. Tablet1000 User manua l Copyright © Qingdao Hantek Electronics Co., LTD 46
