The
Scale
options allows you to scale the computed waveform.
The
Offset
option allows you to set the offset on the computed
waveform.
To perform math computation of acquired waveform
1
On the FFT & Math control panel, click on the Activate Math
Function checkbox to enable the Math function.
2
On the Math Function Settings panel, select the function
(Add, Subtract, Multiply, Divide) as desired.
3
Set the vertical scale factors for the selected Math function in
the Scale property box. Then, set the offset of the computed
waveform by using the knob or the arrow keys to adjust the
offset value.
4
Click on the Active Reverse Function checkbox to reverse the
channels' computation if desired. This allows you to flip the
order of operation for the channels.
x (Multiply)
Multiplies Channel 1 and Channel 2 voltage values,
point by point (CH1 * CH2)
/ (Divide)
Divides Channel 1 and Channel 2 voltage values, point
by point (CH1 / CH2, CH2 / CH1). If zero divide by zero,
the result will be 1. If either Channel 1 or Channel 2 is
positive and it is divided by zero, the result will be in
positive infinity. If either Channel 1 or Channel 2 is
negative and it is divided by zero, the result will be in
negative infinity.
