Setting the Computation Parameters
7. Use jog shuttle & SELECT to set the following items of computation parameter
User1.
• Turn ON/OFF the computation parameter display (Mode box).
• Select the first measurement target waveform or constant from CH1 to CH8/
4*, Math1, Math2, None or Const1 to Const4 (Trace box of Area1).
• Select the first measurement parameter (Item box of Area1).
• Select the operator from +, –, ∗, and / (Ope box).
• Select the second measurement target waveform or constant from CH1 to
CH8/4*, Math1, Math2, None or Const1 to Const4 (Trace box of Area2).
• Select the second measurement parameter (Item box of Area2).
• Set the unit (Unit box) as necessary.
* On the DL7440, you can select from CH1 to CH4, Math1, Math2, None or Const1 to
Const4. On the DL7480, you can select from CH1 to CH8, Math1, Math2, None or
Const1 to Const4.
8. Repeat step 7 to set computation parameter User2 to User4.
9. Use jog shuttle & SELECT to set constants Const1 to Const4.
Computation
parameter User4
Select the first measurement target
waveform or constant from CH1 to
CH8 (4), Math1, Math2, None or
Const1 to Const4.
Tu rn ON/OFF the display of
the computation parameters.
Select the first measurement parameter.
Select the operator from +, –, ∗, and /.
Select the second measurement target waveform
or constant from CH1 to CH8 (4), Math1, Math2,
None or Const1 to Const4.
Select the second measurement parameter.
Set the unit as necessary.
Set constants Const1 to Const4.

10. Press ESC. The Item Setup dialog box closes.
Setting the Measurement Range Area1 of the First Measurement Parameter
11. Press the Time Range1/Time Range2 soft key to set the jog shuttle control to
Time Range1, Time Range2, or both Time Range1 and Time Range 2.
• If you select Time Range1, you can move Time Range1.
• If you select Time Range2, you can move Time Range2.
• If you select both Time Range1 and Time Range2, you can move Time Range1 and
Time Range2 horizontally without changing the spacing between the two. The value of
the digit being specified by Time Range1 changes.
12. Turn the jog shuttle to set the measurement range Area1.
