MS400 Version 2.0 – December 2007

To perform a CH1+CH2 waveform calculation:

1. Press the MENU key and the function menu will appear at the right of the screen.

2. Press the MENU UP or MENU DOWN key to select WAVE MATH. Five options are

displayed at the bottom of the screen.

3. Press the F3 CH1+CH2 key and the obtained waveform M appears on the screen.

Press the F3 key again to close the waveform M.

4. Press the OSC OPTION key and the following will be displayed on the screen:

LEFT/RIGHT – Time Base

UP/DOWN – CH1 Volts/Div

5. Press the OSC UP or OSC DOWN key to adjust the amplitude of the waveform M.

6. Press the OSC OPTION key twice and the following will appear:

LEFT/RIGHT – Time

UP/DOWN – CHM Zero

7. Press the OSC UP or OSC DOWN key to adjust the position of waveform M.

Setting the Trigger

The trigger defines the start time for data acquisition and waveform display. When

beginning to acquire data, the oscilloscope collects sufficient data to draw the waveform at

the left side of the triggering point. After a trigger is detected, the oscilloscope gathers

enough data to draw the waveform at the right side of the triggering point.

To configure a trigger mode setting:

1. Press the MENU key and the function menu will appear at the right of the screen.

2. Press the MENU UP or MENU DOWN key to select TRIG MODE and five selectable

items will be displayed at the bottom of the screen.

3. Use the F1 through F5 keys to make selections.

4. Press the OSC OPTION key and the following will be shown on the screen:

LEFT/RIGHT – Time

UP/DOWN – Trig

5. Press the OSC UP or OSC DOWN key to adjust the trigger level positions.
