Note: Customised parameters are for quick
parameter measurement. The measurement menu
of your oscilloscope is capable of measuring 26
waveform parameters. Two of them (delay and phase
for advance measurement) are generally used when
you do not require to measure all parameters but only
a few. You can set these as customized parameters.
Customized parameters are displayed on the screen.
Automatic measurement of voltage parameters
•
The DSO series oscilloscope can automatically measure the following voltage
parameters.
•
Peak to peak value (Vpp) - the voltage value from the highest point to lowest point
of the waveform.
•
Maximum value (Vmax) - the voltage value from the highest point to ground of the
waveform.
•
Minimum value (Vmin) - the voltage value from the highest point to ground of the
waveform.
•
Amplitude value (Vamp) - the voltage value from top to base of the waveform.
•
Mean (Vmid) - half of the amplitude value.
•
Top value (Vtop) - the voltage value from the level top to ground of the waveform.
•
Base value (Vbase) - the voltage value from the level base to ground of the
waveform.
•
Overshoot - the ratio value of the difference between maximum value and top value
of the waveform to the amplitude value.
•
Pre-shoot - the ratio value of the difference between minimum value and base value
of the waveform to the amplitude value.
•
Average value - average amplitude of signals within 1 cycle.
•
RMS value - the effective value. Energy generated by AC signal conversion during
one cycle with respect to the DC voltage that produces equivalent energy.
Automatic measurement of time parameters
•
The DSO series oscilloscope can automatically measure the frequency, cycle, rising
•
time, falling time, positive pulse width, negative pulse width delay positive duty ratio
negative duty ratio and nine time parameters.
•
Definitions are as follows:
Setup
CH1, CH2
