The "Link Test" window provides you with three link test options to assist you
in analyzing the link test data:
Test results - provides measurement results of the link test.
Test history - provides graphical results of the link quality.
Log Settings - set the measurement parameters to record test results for
future analysis.
Test Results Tab
The Test Results tab is your primary screen to analyze link test results using the
following indicators:
Signal to noise radio (SNR)
Received messages
Signal to Noise Ratio (SNR)
The signal to noise ratio (SNR) identifies the communications quality of radio
path between your station and the link test partner. This indicator is updated
dynamically according to the actual status of the radio link.
The color of SNR indicator relates to the following levels of communications
quality
.
Color
• Green
• Yellow
• Red
If the level of SNR is lower than expected the signal level and noise level
indicators may help you investigate the cause:
A low signal level indicates that the "strength" of the radio signal is fairly
low: i.e. your Clien tManager station is almost 'out-of-range' of its link test
partner.
A high noise level indicates a source of radio interference in the radio path
between the two link test partners.
Comparing the values for your station and the link test partner will help you
to identify the location where the interference occurs, and investigate
whether any actions to eliminate or remedy the source interference resulted
in a better performance.
Received Messages
The indicator "Received Messages" provides a way to determine the efficiency
of the radio path between your Client Manager station and the link test partner.
