5.1 ERRORS OF GENERATION OF SWEEP WAVEFORM

There are three most commonly used measure of sweep voltage. Sweep error displacement error and transmission error. These are called sweep parameters.

Sweep speed error (e_s)

It is important for sweep generator to keep sweep speed. Any change in sweep deviates sweep voltage from maintaining linear slope. The error due to sweep speed is called sweep speed error or slope error. It is given as

$e_s=\frac{Differenceinslopeatbeginningandendofsweep}{Initialvalueofslope}$ …(5.1)

5.2 DISPLACEMENT ERROR (E_D)

It is defined as the maximum difference between the actual sweep voltage and linear sweep which passes through the beginning and end points of the actual sweep ...
