 What is MadPLL®?
MadPLL® is an integrated solution that includes the digital phase lock loop (PLL) controller, software, sensor amplifier board and resonant probe mounting board. Simply add your Akiyama probe or tuning fork to the probe board to create a powerful force sensor for scanning probe measurements.
The MadPLL® package includes the MadPLL® digital PLL controller, sensor board, probe board, and MadPLL® software. Ease of integration with resonant probes and Mad City Labs' low noise nanopositioning systems give users the ability to create high performance, low cost NSOM and AFM instruments.
The PLL controller contains a digitally controlled proportional integral (PI) loop designed to work seamlessly with Mad City Labs’ nanopositioning systems. The addition of closed loop nanopositioners adds to the high performance of MadPLL®. Additional options are available for multi-axis closed loop nanopositioning control.
The PLL controller has three operational modes: self oscillation, PLL driven, and (lock-in) DDS driven. The probe can be controlled in constant excitation or constant signal mode. Measured outputs from the controller include changes in frequency, amplitude or phase shift.
The digital MadPLL® controller has three operational modes: self oscillation, PLL driven, and DDS driven. The probe can be controlled in constant excitation amplitude or constant signal amplitude. Changes in frequency, amplitude, or phase are measured for Z control.
The MadPLL® package includes a digital phase lock loop (PLL) controller, software, sensor amplifier board, and resonant probe mounting board. MadPLL® includes five (5) each of the vertical, horizontal, Akiyama, and blank probe boards. In addition, each unit is shipped with five (5) tuning forks. Additional probe boards and tuning forks can be purchased separately.
The sensor amplifier and probe board assemblies are compact and can be fitted to existing instrumentation. The probe board simply plugs into the sensor amplifier board. The sensor amplifier board can be mounted to a precision positioner such as a closed loop nanopositioning system. The probe board has been designed for use with tuning forks and Akiyama probes. These probes are easy to mount and alignment free.
