6.
Use
jog SELECT
to set the values before scaling, P1:X and P2:X.
•
You can also read the measured value into P1:X by selecting Get Measure P1:X and
pressing Exec.
•
You can also read the measured value into P2:X by selecting Get Measure P2:X and
pressing Exec.
7.
Use
jog SELECT
to set the scaled values (values after scaling), P1:Y
and P2:Y.
Set the value corresponding to P1:X in P1:Y and the value corresponding to P2:X in P2:Y.

to enter the unit.
For the procedure to set the character string of the unit, see section 4.2.

Explanation
Selecting the Linear Scaling Method
Select the linear scaling method from the following:
OFF
Disables linear scaling.
AX+B
Scaling is performed using the specified scaling coefficient A and offset B according to the
equation shown below. Cursor measurement values and automated measurement values of
waveform parameters are displayed using scaled values. You can also assign a unit to the
scaled value.
Y = AX + B (where X is the measured value and Y is the scaling result)
P1-P2
Specify arbitrary scale values (P1:Y and P2:Y) for the values of two arbitrary points (P1:X and
P2:X). The conversion equation (y = ax + b) is derived from these four values.
•
Range of values of the two arbitrary points (P1:X and P2:X)
Same as the measurement range. You can also read in the measured values.
•
Range of scale values (P1:Y, P2:Y)
–9.9999E+25 to +9.9999E+25
•
Initial scale values
P1:X +0.0000E+00, P1:Y +0.0000E+00
P2:X +1.0000E+00, P2:Y +1.0000E+00
