better cabling performance.
6
The limit line (in red) for ACR-F. The higher the
measurements rise above the limit line, the better the
cabling performance. If the line is black, ACR-F is not
evaluated at those frequencies. See page 3-13. Press

The cursor and its location on the frequency scale. When you
first view the plot, the cursor is placed at the worst margin.
Use

press
Change To Cursor first).
The measured ACR-F and margin at the cursor's position.
Margin is the difference between the measured value and
the limit. Margin is negative if the pair failed.
The horizontal scale is the frequency range in megahertz.
The vertical scale is the ACR-F range in decibels.
