All boards need to be inR2The frequency can be adjusted by welding a suitable resistor on the position. Adjustment range300mHz Suitable for constant temperature crystal oscillator with low aging index
The second version is welded on the basis of the originalR2Location，The adjustable resistor is changed5KOr10KVersion improves versatility，Adjustment range3HzLeft and Right At the same time, part of the adjustment operation was sacrificed.。
PCBThe size is slightly larger than that of the first version, which improves the problem of constant temperature crystal oscillator extrusion potentiometer.。The selection option of reference voltage inside the constant temperature crystal oscillator is canceled and the external reference voltage is directly used.。
