voltage variable attenuator

This will be used for ISS in ACAV loop. It will be connected between the oscillator and the amplifier (see the schematic below).

The feedback signal will be sent to the attenuator to change the amplitude, thus changing the power of the diffracted beam in order to stabilize the power.
