ANC350 multi-functional piezo controller for driving attocube’s closed loop positioners The ANC350 is attocube’s high-end piezo controller which meets the highly demanding dynamic performance and accuracy requirements of multi-axis nanopositioning setups. Dedicated controller models for driving up to three positioners either with resistive (ANC350/3/RES) or optoelectronic encoders (ANC350/3/NUM) are available. Modes of Operation open loop positioning Open loop positioners can be controlled in closed loop mode in combi- nation with the ANC350/3/FPS and attocube’s stunning interferometer FPS1010, FPS3010, FPS3010-19” setups (see attoSensorics section) . Output Signals stepping and fine positioning of attocube positioners stepping - voltage range 0 .. 70 V stepping - frequency range 0 .. 2 kHz closed loop positioning depending on encoder system stepping - maximum current > 8 A peak capacitance measurement 50…5000 nF resolution of signal generation 1.1 mV (16 bit) remote operation  USB 2.0, ethernet optional output noise <8 mVpp (20 MHz bandwidth) output filte
