Enhanced Parameter Measurement (Enhanced)
The enhanced parameter measurement feature allows you to perform automated measurement of the waveform
parameters of two areas. It also allows you to perform calculations using the automated measurement values of
waveform parameters.
You cannot use the enhanced parameter measurement feature when the statistical processing mode is set to
Cycle.
Configuring Area2 (Item Setup for Area2)
You can configure measurement items and other settings of the second area (Area2). The method to set the
range is the same as that for the automated measurement of waveform parameters.
Source Window (Time Range (Area2))
Selects the source window for Area2. The method to set the range is the same as that for the automated
measurement of waveform parameters.
Measurement Time Period (T Range1/T Range2)
Set the measurement range of Area2. The method to set the range is the same as that for the automated
measurement of waveform parameters.
Calculation Using Waveform Parameters (Calc Setup)
You can define four calculations (Calc1 through Calc4) that use the automated measurement values of waveform
parameters.
Name (Name)
You can specify a name of up to eight characters in length for the computation that you have defined. The
specified name is displayed on the screen.
Expression (Expression)
Be sure to include a waveform parameter in the expressions. The available operators and how to use them are
described below.

Exp
Exponent. Used to enter a number in scientific notation in expressions.
(1E+3 = 1000, 2.5E−3 = 0.0025)
Displayed as “E” in expressions to distinguish this from the “EXP” operator.
PI
Pi (π)
e
Euler’s number, base of the natural logarithm
(e = 2.71828…)
Displayed as “eul” in expressions to distinguish this from the “E” that
represents exponents.
