Microtest TSB-67 - 568A Annex E Analyze LAN Traffic, Peak-to-Peak Noise, LAN Traffic Display

Page 46

Peak-to-Peak Noise

To display the PEAK-TO-PEAK-NOISEscreen, press the Measure Cable Performance key, then select P-P Noise.

The pairs are shown on the left and the Peak-to-Peak Noise values are shown on the right.

If the Peak-to-Peak noise level exceeds 3,000 mV, OVR (Overrange) is displayed.

The measurement’s bandwidth covers a range of 40 KHz to 30 MHz.

Press the ESCAPE key to return to the Measure Cable Performance screen.

Chapter 7: Analyze LAN Traffic

Analyze LAN Traffic is a built-in network monitor that shows the current level of LAN traffic activity and monitors network traffic for up to eight hours with the interval set to 5 minutes (using the AC adapter as a power source).

The Analyze LAN Traffic feature is useful for tracking down intermittent faults. It can also help you decide if your network needs a bridge or a router because of excessive LAN traffic. It provides even greater flexibility in locating problems, by letting you change the traffic sampling interval simply by pressing Setup (F4).

Note: Analyze LAN Traffic does not monitor Token Ring network traffic.

LAN Traffic Display

To display the TRAFFIC screen, press the Analyze LAN Traffic key. The ANALYZE LAN TRAFFIC screen displays two graphs. The large graph on the left shows a historical “skyline” of activity; representing the percent utilization of the total network. The small bar graph on the right indicates the current level of activity. This indicator should change frequently because of the volatile nature of most network activity. If it is always off or always fully on, you may have a serious problem with your cabling system or LAN hardware.

Press Clear (F2) to reset the graph.

Press Scale (F3) to toggle between linear and logarithmic scale.

Press Setup (F4) to configure the monitor.

Press the ESCAPE key to exit.

The Traffic level indicator shows relative activity as follows:

0 No network activity

1-10 Typical network traffic

11-20 heavy network traffic

21-40 Very heavy traffic

41-60 Overloaded network

61-99 Probable defective component
