Overview
Equation Editor allows you to enter an algebraic equation of standard
mathematical operators and functions, referencing data that is available in
the E4990A. Once a valid equation is entered and enabled, the display of
the active trace is replaced with the results of the equation, and updated in
real-time as new data is acquired. For equations that can be expressed
with Equation Editor's supported functions, operators, and data, there is no
need for off-line processing in a separate program.
For example, on entering the equation "Z=ACV/ACI" in the E4990A
Equation Editor (2c in the Figure below), the resulting trace is computed as

(Max: greatest measured value between markers 1
and 2.; Min: smallest measured value between
markers 1 and 2.)
