Determining Hub Port Capabilities (Model Dsp-2000) - Fluke DSP-100 User Manual

Noise Test Results
As the noise test runs, the displayed test results are updated every second after the
first 10-second sample period. Table 4-8 describes the items on the screen.
Item
The minimum level of noise that is considered to be a noise hit. The default
threshold is 270 mV. If you want to change the fault threshold, see the earlier
section "Changing the Impulse Noise Threshold."
The overall result of the noise test. Displayed only when 10BaseT is
selected. A
than two noise hits. A
detected during a 10-second interval.
The average number of noise hits per second since the start of the test.
The highest number of noise hits per second and the time at which the peak
was recorded.

Determining Hub Port Capabilities (Model DSP-2000)

This test determines if a hub supports the following standards:
Auto-Negotiation
10BaseT
100BaseTX
100BaseT4
100BaseTX Full Duplex
10BaseT Full Duplex
To determine hub port capabilities, proceed as follows:
1. Use a patch cable of the correct impedance to connect the network connection
to the test tool's MONITOR jack.
2. Turn the rotary switch to MONITOR.
3. Use D to highlight
