Displaying measurement result in deviation from reference value (deviation
measurement mode)
Functional description
The deviation measurement feature allows you to display deviation values
instead of actual measurements. A deviation is expressed as the difference
between the actual measurement and the stored reference value. The deviation
measurement feature is useful when you observe how a particular value of a
device/component changes under varying conditions of temperature,
frequency, bias, and other influences.
You can apply the deviation measurement feature to the primary or secondary
parameter or both. The deviation measurement feature supports the following
two modes:
•
ΔABS (absolute value) deviation measurement
Identifies and displays the difference between the actual measurement of
the DUT and the stored reference value. This value is calculated based on
the following formula:
Softkey Description
D.P. AUTO Automatically sets the decimal point
D.P. FIX Fixes the decimal point position
D.P. POS INCR+ Increments the position of decimal point
D.P. POS DECL- Decrements the position of decimal point
ΔABS = X-Y
