Applying a high amount of excitation to the crystal unit increases properties such as particle removal. The frequency band can be changed by replacing the sub-board.

Principle      Oscillation
Oscillation RangeMain board 40 to 54 MHz 
Sub-board 9 to 40 MHz (4 types)
CI: up to 300 Ω
Excitation LevelUp to 15 mW
Level varies depending on crystal conditions.
Dimensions150(W)x130(D)x13(H)
