Antenna Analyzer AIM4170 page 17
Average Readings-
Each data point is obtained by averaging two or more ADC
readings to reduce the effect of measurement noise. When
this option is selected, “AVG =N” appears in red in the
upper right corner of the graph. N is the number of readings
being averaged and is between 2 and 16.
Comm Port --
Enter the RS232 port used for communication.
Port values can be 1 to 8. This is saved in the initialization file
that’s read each time the program is started.
Morse -- Three values can be sounded out:
Sxx.xx= SWR, Zxx.xx=Zmag, Txx.xx=Theta.
The decimal point is coded as “R”. This is active when
the “Measure Point” function is used (see above). Morse output
is
enabled by clicking the “ON” button and disabled by the “OFF”
button.
AutoPwrOff
This button enables/disables the automatic power down feature of
the analyzer. The enable/disable flag is saved in the analyzer
initialization data when you exit from the program (QUIT) and
restored each time the program is started again. The green LED
on the front panel of the analyzer blinks when this command is
executed. The default timeout delay is 10 minutes.
If you never use batteries, you may want to leave this feature
turned off.
BANDS:
Highlight --
Highlight the amateur radio frequency bands. These frequencies
are specified in the configuration file (*.cfg). The start/stop limits
do not have to be the actual amateur bands. The highlight color
can also be specified in the config file.
160..2 meters
Click on the desired band to set the start/stop scan limits and the
frequency step between measurement points. These limits can be
changed in the configuration file.
Band A..D User specified band limits. Same as above.
