Cable Testing with the FrameScope 350 3

Viewing Result Details

Agilent FrameScope 350 User’s Manual 85

boundary on passing test plots. On failing test plots, the Worst Margin

button places the line at the frequency where the results exceed the

acceptable limits the most. You can move the cursor around the plot

screen by pressing the area you want to see and then using the scroll

rocker to fine tune the location. The frequency of the cursor is displayed

and the values in the table correspond to the cursor location.

A chart below the plot shows detail results of the current location of the

cursor at the FrameScope and DualRemote, and the limits for the test

parameter, as follows:

Data: This is the worst case of the test results at the cursor location.

Limit: The limit of passing results, set when the test standard is chosen

at the cursor location.

Margin: The difference between the Data value and the Limit value at

the cursor location.

The plots are color coded for different wire pairs. The plot lines

displayed can be changed by pressing Settings and selecting All Plots,

All Local Plots, All Remote Plots, Worst Case Plot, or Select Single Plot.

You can also choose to show plots to 100 MHz, 250 MHz, or 350 MHz ,as

long as the test was run to the frequency selected. For example, if the

test was run to 250 MHz, you could not see plots to 350 MHz. See “Setting

the Maximum Frequency” on page 132.

Locator Screens

Locator screens aid in finding faults on the tested cable. The examples

above show Locator screens for a passing test, at left, and a failing one,

at right. Note the difference in the plots, where the failing result shows a

peak where the failure occurs. The tape measure provides a reading of

where the failure occurs. It will be placed on the right-hand side of the

screen if showing the distance from the DualRemote. If there are more

than one peak, you can press the plot area near the peak and fine tune
