Example 1:

To display the measurement peak-to-peak value of Channel A, follow the steps below:

1. Press [A] to turn on Channel A.

2. Press [SCOPE] to enter the frequently used function menu.

3. Press [F2] to enter the parameter measurement options.

4. Press [F1] to select customized parameter for parameter measurement.

5. Press [F2] to select parameter 1 as the customized parameter.

6. Press [F3] then turn the jog dial to select peak-to-peak value, then press the jog

dial once to confirm. The screen will exit from the current menu.

7. Press [F4] to select Channel A.

8. Press [F5] to set indicator to parameter 1.

The peak-to-peak value is displayed in the top right corner, as shown below :

Note : Customized parameters are for quick parameter measurement. This device

has 27 measurement parameters. In general use, the user is not required to measure

all parameters. Only a few have to be tested. In this case, set the parameters you

require as customized parameters. All such parameters will be displayed on the

screen.

Automatic measurement of parameters

Your oscilloscope can automatically measure the following voltage parameters :

Maximum value (Vmax) : The voltage value from the highest point to ground (GND) of

the waveform.

Minimum value (Vmin) : The voltage value from the lowest point to ground (GND) of the

waveform.

Top value (Vtop) : The voltage value from top to ground (GND) of the waveform.

Base value (Vbase) : The voltage value from base to ground (GND) of the waveform.

Middle value (Vmid) : Half of the amplitude value.

Peak-to-peak value (Vpp) : The voltage value from the highest point to lowest point of the

waveform.

Amplitude value (Vamp) : The voltage value from top to base of the waveform.

Overshoot : The ratio value of the difference between maximum value and top value to the

amplitude value.

Preshoot : The ratio value of the difference between minimum value and top value to the

amplitude value.

Average value : Average amplitude of signals within 1 cycle.

Root mean square value (Vrms) : The effective value. Energy generated by AC signal

conversion during 1 cycle with respect to the DC voltage that produces equivalent energy,

i.e. root mean square value.
