How to measure PLL/PID bandwidth under real experimental conditions

on 14.11.2017 at 10:52 by Romain Stomp

With the merging of PLL and PID tab in LabOne for MFLI and UHFLI, the PID Advisor section is now identical for both type of feedback loops and various system models can be tested. After all, a Phase Locked-Loop (PLL) […]

How to Achieve More Stable Z-feedback in FM-AFM Mode

on 15.05.2014 at 16:38 by Romain Stomp

The challenge with FM-AFM mode (or NC-AFM for Non-Contact Atomic Force Microscopy) is that tip-sample interaction can be either attractive (negative frequency shift, -df) or repulsive (positive frequency shift, +df) which leads to different parameter settings for the Z feedback […]
