Timing Parameters - Tenma 72-14520 Instructions Manual

Voltage Parameters
• The following parameters can be measured automatically:
1. Vmax: Voltage at the highest point with respect to GND
2. Vmin: Voltage at the lowest point with respect to GND
3. Vtop: Highest stable voltage
4. Vbase: Lowest stable voltage
5. Middle: Midpoint between highest and lowest stable voltage
6. Vpp: Vmax – Vmin
7. Vamp: Vtop – Vbase
8. Mean: Average amplitude of the waveform on screen
9. CycMean: Average amplitude of a waveform in one period
10. RMS: The effective value. According to the energy produced by the AC signal in
the conversion, the equivalent energy that the DC voltage corresponds to
11. CycRMS: The RMS of one period
12. Overshoot: The ratio of the difference between Vmax and Vtop
13. Preshoot: The ratio of the difference between Vmin and Vbase
14. Area: The product of time and voltage for all points on the screen
15. CycArea: The product of time and voltage for all points in one period

Timing Parameters

• The following parameters can be measured automatically:
1. Period: The duration of one cycle of a repetitive waveform
2. Frequency: The reciprocal of the period
3. Rise time: The time it takes the waveform amplitude to increase from 10% to 90%
4. Fall time: The time it takes the waveform amplitude to decrease from 90% to 10%
5. +Width: The width of a positive pulse at 50% amplitude
6. -Width: The width of a negative pulse at 50% amplitude
7. +Duty: The ratio of positive pulse width to period
8. -Duty: The ratio of negative pulse width to period
