Chapter 3 Using HP BenchLink/Arb

Performing Waveform Math

5If the waveform copied to the Clipboard has a different number of points than the selected waveform, you can click the MATCH LENGTH button. This will adjust the size of the Clipboard waveform to match the first operand. Click it again to undo the match length operation.

6If, as a result of the math operation, the new waveform exceeds the

vertical limits of the window, scale and fit the waveform to the window

 

by clicking the FIT AMPLITUDE button. Click the button a second time to

undo the fit operation.

 

7Click OK to complete the math operation or CANCEL to abort the process.

Using Standard Waveshapes in Math Operations

1Select the first operand. This can be an individual segment or the entire waveform.

2Select the mathematical function (Add, Subtract, or Multiply). The Math dialog box will appear.

3Click the STANDARD WAVE button. The New Segment dialog box appears, prompting you to select a standard waveshape as the second operand. The number of points in this dialog box cannot be changed. This ensures the number of points in the first operand and the second are identical. Click OK.

4The first operand of the mathematical operation is displayed in the window on the left. The second operand (a standard waveshape) appears in the middle window and the resulting waveform is displayed on the right.

5If the resulting waveform is not what was expected, click the REDO button to change the second operand for the math operation.

6If, as a result of the math operation, the new waveform exceeds the vertical limits of the window, scale and fit the waveform to the window by clicking the FIT AMPLITUDE button. Click the button a second time to undo the fit operation.

7Click OK to complete the operation or CANCEL to abort the process.
