The next automatic selections are made when this tuning function is activated:
– active unit = RX
– operation mode = continuous
The following window will appear to the display after the function is activated:
The D/A converter range (DAC) is from +1023 to –1024 and voltage range is
from 0.25 V to 4.45 V (voltage precision is 0.01V).
The frequency error range is from –134 kHz to +134 kHz with the precision
0.1 kHz. The rounding is made to the closest value.
