Waveform Computation

Explanation
Turning the Computed Waveform Display and Computed Waveform Label ON and OFF
See section 9.1.
Operator
Select the operator Pass-Thru as the operator for Math1 and Math2. Select the Pass-
Thru operator when displaying the waveform to be computed that has been simply
scaled or smoothed. For details smoothing, see section 9.2.
• When using the Pass-Thru operator and smoothing is ON
The waveform to be computed is displayed after smoothing.
• When using the Pass-Thru operator and smoothing is OFF
The waveform to be computed is displayed without smoothing.
Waveform to Be Computed
The waveforms on which computation can be performed are as follows:
• For the DL1735E/DL1740E/DL1740EL
Computation Name
Source
Math1
One channel from CH1 to CH4
Math2
One channel from CH1 to CH4 or Math1
• On the menu, CH1 to CH4 may be indicated as C1 to C4 and Math1 as M1.
• Math1 and Math2 can be computed simultaneously.
• For the DL17420E
Computation Name
Source
Math1
CH1 or CH2
• On the menu, CH1 to CH2 may be indicated as C1 and C2.
Scaling
The operation is the same as for addition, subtraction, and multiplication. See section
9.2.
Unit of Computed Waveforms
The operation is the same as for addition, subtraction, and multiplication. See section
9.2.
Smoothing
The operation is the same as for addition, subtraction, and multiplication. See section
9.2.
Effects of Linear Scaling
If linear scaling is performed on the channel to be computed, computation is performed
using linearly scaled values.
Maximum Record Length That Can Be Computed
The operation is the same as for addition, subtraction, and multiplication. See section
9.2.
