Features

1、Support 0-55MHz continuous adjustment, the frequency is 1Hz.
2、The generator has a 78L05 voltage regulator. When the input current is 200MA, the input voltage of 8-9V will be the ideal voltage.
3、The 12V input voltage can only be used for short-term testing, otherwise it will cause the board to heat up.
4、5p/6p connect to encoder as per photo. 7p of the middle connects to digital matrices input. 14p (8V GND) is 8V power supply from main board.
5、If powered by the motherboard, the DDS does not require a separate power supply.
6、1 to 6 correspond to 6 frequency bands: 3.8, 7, 9, 14, 18 or 21, 27 or 29.
7、ISB, USB, CW are the three mode choices.
8、DT is a signal from main board.
