3.3.1.7.- Positioning antennas
When this menu button is selected, it gives you the option of enabling (ON) or disabling (OFF)
the aerial directing function.
This function has been designed to give the installer a reference in regard to signal reception
quality, at the moment of directing an aerial, without his needing to view the data shown on
the equipment screen.
It is an acoustic signal, in the nature of an intermittent beep, whose intermittency and tone
frequency depend on the quality of the signal on the channel that has been tuned.
The signal reception parameters that this function measures to generate the sound signal
depend on the operating mode of the equipment: if digital measurements are being made, the
parameters taken into account are power and C/N; if analog measurements are being made,
the parameters evaluated are level and C/N.
The sound signal variation is as follows:
If the field meter is in the spectrum analysis mode, the function takes as its reference the
reference level that has been selected. This means that the tone will be more high-pitched the
closer to reference values in level or power, in the case of analog or digital measures,
respectively.
The intermittency speed will increase as a function of the C/N of the signal received.
The beeps will be faster (less time between beeps), the higher the C/N. Conversely, the
beeps will be slower (more time between beeps) the lower the C/N of the signal
received.
The tone frequency (high or low-pitched tone) will be greater (high-pitched tone) the
greater the level in the case of analog measurements or the greater the power in the
case of digital measurements
. Conversely, the tone frequency will be lower (low-
pitched tone), the lower the level or power, in the case of analog or digital measures,
respectively.
