Function
This function lets you apply linear scaling to the measurement values. If you set this feature
ON, the screen displays the scaled results rather than the original measurements. The scaling
relationship is
Y = AX + B
where X is the measurement value and Y is the scaled value. Note that you can select the
dimensional unit for the scaled display.
Scaling coefficient (A) and offset (B)
Range for A, B : –1.0000E+30 to +1.0000E+30
Default
: A +1.0000E+00, B +0.0000E+00
Dimensional unit
Unit identifier (alphanumeric string) of up to four characters.
Displaying Upper and Lower Limits
Depending on the values of A and B for the linear scaling, the upper and lower limits of the
vertical axis for displaying the waveform may not be well-rounded values. If you set “Linear
Scale Rounding” to ON, the waveform is displayed so that 1 div of the vertical axis is adjusted
to well-rounded values of 1-2-5 steps.
Example
If 5.0V/div, A=1.2345E+00, and B=5.4321E+00, the upper and lower limits of the waveform
display are as follows.
“Linear Scale Rounding” is OFF : 3.0122E+01/-1.9258E+01 (0.00/div)
“Linear Scale Rounding” is ON : 5.000E+01/-3.000E+01 (1.000E+01/div)
Operating Procedure
1.
Press a channel key (
CH1
to
CH16
) to select the channel you want to set.
2.
Press the “
Next 1/2
” soft key.
3.
Press the “
Linear Scaling
” soft key to select ON.
4.
Press the “
Ax+B:A
” soft key, and then set the A value using the jog shuttle.
You can use the arrow keys to move to different columns within the value.
5.
Press the “
Ax+B:B
” soft key, and then set the B value.
6.
If necessary, press the “
Units
” soft key and enter the unit string at the keyboard.
