9.3 Setting Computing Range and Display Units, and
Recomputing
Function
Computing range (Start Point/End Point)
• The instrument can execute automatic computation on up to 400 kW. When displaying a
waveform of 400 kW or more, computation on all of the data cannot be performed at once.
• You can set the start and end points to any area along the time axis (from -5div to +5div from
the screen center). The start point is indicated by a dot-dash line on the display, while the end
point is indicated by a dashed line. The setting step is: T/div x 10
÷ displayed-record-length.
Note that the “displayed record length” is not always identical to the “record length” in the
acquisition memory. For details, refer to Appendix 1.
• Please re-execute the computing each time you change the computing area.
Displayed unit (Unit Math1, Unit Math2)
You can enter any dimensional unit (up to 4 characters). The selected unit is reflected in the
scale values.
Recomputing (Exec)
When this instrument is displaying the computing results using auto scaling, scaling is not
carried out for every data update. Please re-execute the computing as necessary to maintain
proper scaling, and whenever you change the computing range.
Operating Procedure
Setting the computing area
1.
Press the MATH key.
2. Press the “ Mode ” soft key as necessary to select “ Basic ”, “ Phase ”, “ Binary ”, or
“ User ”.
3. Press the “ Start Point/End Point ” soft key so that the jog shuttle is set to Start Point.
4. Turn the jog shuttle to set the start point.
5. Press “ Start Point/End Point ” again to set the jog shuttle to End Point. Then turn the jog
shuttle to set the end point.
6. Press the “ Exec ” soft key to re-execute the calculation.
Setting the displayed unit
3.
Press the “ Next ” soft key several times to display the screen for setting the displayed unit.
4. Press the “ Scale & Unit ” soft key to display the scaling value setting menu. Move the
cursor to “ Unit ” and press SELECT key to display the keyboard. Then, enter the character
string of the unit.
Repeating the computing
3.
Press the “ Exec ” soft key to re-execute the computing.
