EtherAnt II User’s Manual
Figure 3.14 – Diagnostic Utility Screen
Partner Name –
The name of the EC that you are communicating with.
SNR (Signal-to-Noise Ratio) –
The ratio measuring the difference between the signal level and the noise
level.
Signal Level –
This bar-field displays the amount of signal (in dB) communicated from the EC you are
connected to.
Noise Level –
This bar-field displays the amount of ambient interference (in dB) in the wireless
environment.
Sample Time –
This field sets the time interval between diagnostic readings.
Clear –
Clicking this button will clear the statistics displayed on the screen.
As diagnostic packets are received, the diagnostic utility screen will update the number of successfully
received packets at each specified rate.
These signal levels are also very useful for aiming the antenna. Adjust the aim such that you get the best
signal strength with the highest possible SNR. The signal levels appear as horizontal bars that change
colors depending on the strength of your signal. Green means an excellent signal; yellow means a good
signal; and red means a poor signal.
If the Partner is an amplified base station, the weakest link will be the SNR of your signal into it.
NOTE:
The signal level information will only appear in the Partner’s section of the screen if you are
communicating with a device with an Agere or YDI Diamond WLAN card in it (such as an EC,
AP-500, AP-1000, AP-2000, etc.).
