5.4 Operation Between Waveforms
b) Clipboard
Clicking the
Clip Board
button or pressing
Alt
+
B
displays the waveform stored on the clipboard
in the
[Clip Board/Created Waveform]
area. Clipboard: “4.7.2 Clipboard”
If the selected range is longer than the clipboard, the overflowing part of the waveform is treated as
zero data.
If the clipboard is longer than the selected range, the first part of the clipboard is used.
Though data on the clipboard are in 16-bit integers (
− 32768 to +32767), they are converted into the
vertical axis unit in the inter-waveform operation. For example, when the vertical axis custom unit
is
− 1 to +1, ±32767 on the clipboard is treated as ±1.
5.4.3 Operation execution
Clicking the
=
button displays the result of inter-waveform operation in [Operation Result] .
Click the
OK
button to return to the waveform display screen and reflect the operation result.
Click the
Cancel
button or press the
Esc
key to return to the waveform display screen without
performing any operation.
It is recommended to set the vertical axis unit to the custom unit: − 1 to +1, especially when
executing multiplication in inter-waveform operation.
Under this setting, the result of multiplying ± full scale values can be a ± full scale value.
When the operation result exceeds the ± full scale value, waveforms are clipped at the ± full scale
value.
Note that dividing a number by 0 results in infinity and an error usually occurs. To avoid such an
error, the result of division by 0 is 0 as an exception in this inter-waveform operation.
