SHIFT
1. Press SHIFT+CH1 to CH6 (DSP1 to DSP6).
Note
For a description of turning ON/OFF the DSP, see section 5.1. For a description of setting
the vertical position, see section 5.4. For a description of zooming vertically by setting the
zoom rate, see section 5.8. For a description of setting waveform labels, see section 8.10.
Setting the Computation Definition
2. Press the Setup soft key. A setup dialog box opens.
3. Use the jog shuttle and SELECT to set Operation to S1+S2, S1–S2, S1*S2, or
S1/S2.
Selecting the Channel on Which to Perform Computation
4. Use the jog shuttle and SELECT to select Source1.
5. Likewise, select Source2
Setting Value/Div
6. Turn the V/DIV knob to set the Value/Div value.
You can also set Value/Div by pressing the Value/Div soft key and turning the
jog shuttle.
Note
There are 123 (selectable range: 10.00E–21 [Value/Div] to 500.0E+18 [Value/Div]) different
Value/Div settings. You set the Value/Div using 1-2-5 steps similar to the V/div setting.
Automatically Selecting the Optimum Value/Div Setting
7. Press the Optimize Value/Div soft key. The optimum Value/Div setting is
automatically selected by referring to the range of the computed channel and
displayed.
Note
• The Optimize Value/Div soft key appears only when Variable is OFF.
• The operation using the Optimize Value/Div soft key selects the optimum Value/Div setting
by referring to the range of the computed channel. It does not select the optimum Value/
Div setting for the output waveform after computation. For easy viewing of the waveform
after computation, select the approximate range using Optimize Value/Div, and then use
the V/DIV knob or Value/Div soft key to adjust to the optimum range.
