The third screen shot shows the average Channel utilisation for each minute up to one hour. It will also give a running
average for the total number of minutes up to 59 minutes.
Figure 65 - RX Noise Floor Minutes
The next screen shot shows the running radio receive noise floor average for each minute up to 59 minutes.
The Channel Survey page also shows two other screen shots (not shown here) which indicate the Percent Channel
Utilisation and Noise Floor in one hour intervals. The screens will only show the last 24 hour period.
4.3 - Custom Survey
Custom Survey is essentially the same as the Channel Survey (explained in the previous section) except the three
channel utilisations can be turned on or off thus showing the different amount of traffic related data.
Percent Radio TX – Any transmitted messages from the radio to other devices.
Percent Radio RX – Any DSSS messages received by the radio (basically any radio data from either WEIDMULLER or
competitor radios).
Percent Busy (CCA or Noise) – Clear Channel Assessment is the detection of any ongoing transmissions or noise, i.e.
Wireless I/O , 900MHz FHSS, Cordless Phones, RC devices, etc.
By configuring the different chart options we can get a clear idea of the amount of data being transmitted, received and
the amount of other noise that can be heard at the radio.
Configure what is to be logged on each chart, select a time interval and save changes and the charts will then be
displayed below the settings. Click the button again to manually redraw the graphs.
Each graph will display a Percent Channel Utilisation using the selected criteria and time interval (Seconds, Minutes or
Hours).
