OC4 The Oscillation Controller - Nanonis

© Nanonis GmbH, Switzerland | www.nanonis.comSYSTEM INTEGRATIONThe OC4 is available as a stand-aloneversion and as an add-on to theNanonis SPM Control System.Up to six analog outputs and two digitallines allow easy integration with anySPM controller.Digital integration with the NanonisSPM controller brings additionaladvantages including the integrateduser interface, direct digital signalcommunication without limitation inrange and resolution, as well asreduced latency.KELVIN CONTROLLER ANDz-CONTROLLERTwo auxiliary outputs can be used tocontrol the bias voltage and thez-signal for tip-sample distancecontrol.Two generic PI controllers allow forvarious Kelvin Probe techniques andz-controller modes.Powerful and easy to use softwaresupports these advanced SPMapplications.SAFETIP TMThe SafeTip TM feature, which preventstip crashes, is especially useful forncAFM.SOFTWAREMany specialized software tools,which have been developed by SPMapplication experts, are designedto help with everyday work.With a few mouse clicks find theresonance, determine the Q-factor,set up the perfectPLL TM parameters,compensate the contact potential,and more.Moving from the routine to the complex:imagine being able to have anoverview of up to four nested PIcontrollers running in parallel.The LabVIEW programming interfacetogether with the option tohave customized functionsprogrammed on the FPGA makesthe OC4 an extremely flexible device.PERFECT PLL TMWith perfectPLL TM easy and perfectoperation of the PLL is guaranteed.The perfect PI parameters arecomputed and configured for anyQ-factor and desired detectionbandwidth.Feedback is stable, ringing orslow behavior is avoided.The only parameter adjustmentneeded is the compromisebetween speed and low-noise.SafeTip TM benefits include longertip life and reduced time spent onreplacing tips.In addition, experimental freedom isenhanced by the reduction of tip risk.
