ANTUNER only researches ultra-small, portable radio peripherals, and completely develops software and hardware at the bottom
Standard tuning operation, basically in seconds. If you want to modify the relevant parameters, refer to Chapter 3.5 for modification.
And some antenna feeder systems are not well grounded, which may cause the antenna tuner to fail to detect even if the output power of the radio station is increased.
e) When entering the automatic tuning state, it will start tuning when it detects that the transmission power voltage is greater than [ TUNE MIN ADC ],
To the radio output signal, at this time, the antenna feeder system should be adjusted to be well grounded.
During the process of automatic tuning, the program will perform automatic tuning in the following order:
All combinations of relays will be controlled sequentially, and matching capacitance and inductance relays will be performed at [ TUNE SETP ] span intervals
a) If the number of user stored results [USER COUNT] is greater than 1, then find the standing wave value from the user stored bit
device, each time a group of relays is controlled, it waits [TUNE DELAY] milliseconds to detect the current standing wave to ensure

Lowest relay combination.
tuning.
If ÿUSER COUNTÿis equal to 0, skip this step.
1) Auto tuning mode
b) Cycle through the automatic storage results [TUNE COUNT] in order to find the relay combination with the lowest standing wave value.
The factory default parameter of this day’s tuning is that when a standing wave ÿ 1.80 is detected, the tuning operation will be started automatically.
c) If a certain relay combination is found to be lower than [ TUNE AUTOSWR ] through steps a and b above, stop tuning
When a standing wave < 1.10 is detected in , the tuning will stop.
harmonious.
The factory defaults to automatically store 10 sets of results this day, and does not enable user storage of results. Basically meet the needs of ordinary users
d) If the relay combination with the lowest standing wave value cannot be found through the above steps, it will automatically enter the tuning state.
