6. TOOLS
AWare built-in installation and system monitoring tools are using
special CLI commands, which are typically not used by the operator
working with the unit through the Hyper Terminal. This list includes
the following commands:
6.1 TEST KIT
The Test Kit is a set of four utilities that facilitate unit installation
and maintenance. AWare tools allow the operator to investigate the
frequency spectrum, to align the antennas precisely, to set a reason-
able output power level, and eventually check the link using the BER
test.
6.1.1 S
PECTRUM ANALYZER
The Spectrum Analyzer test run on an AlphaWave unit is activated
by the SPECTRUM command sent from AWare. By this command the
unit scans the full frequency spectrum defined by the Factory De-
fined Configuration file and stores the measured values of the re-
ceive signal levels (RSL) in the RAM memory. To upload the meas-
ured RSL values from the unit the X-Modem protocol is used.
The Spectrum Analyzer test provides a graphical representation of
the measured RSL values using two-dimensional graphs with the fre-
quencies scaled on the abscissa (y axis) and RSL scaled in dBm on
the ordinate (x axis). The Start and Stop Frequency controls define
the Frequency Span, which determines the scale on the abscissa.
Meanwhile the range of the RSL on the ordinate is fixed and equal to
10 dB, in range of –120 dBm to –20 dBm (Reference Level).
The following controls are available:
• Start Frequency – defines the sweep starting frequency in
MHz;
• Stop Frequency – defines the sweep stopping frequency in
MHz;
