To configure the above parameters, enter the following in the command line:
radio analyse <samples> <interval> < start> <stop>
For example:
radio analyze 100 10 9000 9300
will program the Spectrum Analyser to take 100 samples at every frequency, in 100 kHz steps,
starting at 900 MHz and ending at 930 MHz. If you leave any parameters off the list, they will
be set to the default. In the above example, entering
radio analyze 100 1
would have had the same effect, since 9000 is the default value for Start, and 9300 is the
default value for Stop.
The CCU RSSI that is reported by the Spectrum Analyser is the level of any packets received
from a WaveRider CCU3000 or NCL1900. Unlike other measurements, it is synchronized with
packet reception. Only the value of the last packet received is shown.
NOTE: For each CCU detected, three points will be shown - the center
frequency, and the upper and lower band edges (+
2.8 MHz).
A comment can be added to the analysis using the
radio comment command. This
comment will also be displayed on the graph. For example, entering the following in the
command line:
radio comment Site 1 Spectral Analysis
will display “Site 1 Spectral Analysis” in the line below the date and time.
The command
radio analyse last will redisplay the results of the last analysis that was
performed.
A graphical display of the results is available as a PDF (Adobe Portable Document Format)
document called
specan.pdf, which can be retrieved from the modem through FTP:

Stop The upper boundary on frequencies sampled, also in 100’s of kHz. The
default is
9300 (930.0MHz), which is also the maximum. Again, this is
outside the allowed CCU and EUM transmission range.
