Basic Operations
DS4000E supports the basic operations (addition, subtraction, multiplication and
division) on the channels.
You can perform the basic operations following the steps below.
1. Specify the basic operation
Press MATH Operate, turn the multi-function knob to select the desired
basic operation (addition, subtraction, multiplication or division) and press the
knob. You can also press Operate continuously to switch the current operation.
A+B: addition. Add the waveform voltage values of signal source A and B
point by point and display the results.
A-B: subtraction. Subtract the waveform voltage values of signal source B
from that of signal source A point by point and display the results.
AxB: multiplication. Multiply the waveform voltage values of signal source A
and B point by point and display the results.
A÷B: division. Divide the waveform voltage values of signal source A by that
of signal source B point by point and display the results. It can be used to
analyze the multiple relationships of waveforms in two channels.
Note: When the waveform voltage value of signal source B is 0, the result
of the division is treated as 0.
2. Specify the signal source A and signal source B
1) Press Source A, turn the multi-function knob to select the desired
channel and press the knob. You can also press Source A continuously to
switch the channel currently selected. The channels available are CH1, CH2,
CH3 and CH4.
2) Press Source B and use the same method to specify the signal source B.
3. Adjust the vertical scale and vertical position
Press
and respectively; turn the multi-function knob to adjust the
vertical scale and vertical position of the math operation waveform. Please refer
to “MATH Waveform Vertical Control”.
4. Adjust the horizontal time base and horizontal position
Use HORIZONTAL
SCALE and HORIZONTAL POSITION to adjust
