Specifications of Phoenix AFM Controller

Main board

Xilinx Zynq System on a Chip,  with  Dual 667 MHz ARM® Cortex®-A9 MPCore™ with CoreSight™ running Linux-based real-time OS, with Artix™-7 FPGA, 85 K Logic Cells for digital signal processing.

3 channels of 40 MHz 16 bit ADCs each high speed input has the selection of AC or DC coupling with a 16 bit offset DAC and analog programmable gains from 1 to 1024, so the noise is not limited by the ADC, but by the front end signal noise.

3 channels of 40 MHz 16 bit DACs, these high speed DACs also are configured with 16 bit Gain and Offset DACs, to deliver precise control even at small amplitudes.

8 channels of 1 MHz 18 bit ADCs, these are for closed loop and other auxiliary analog inputs

High-Voltage Module

The High Voltage Module for the MultiMode™, Dimension 3100 (Bruker) series microscopes output range ±220 Volt signals for ±X, ±Y, ±Z, and an optional auxiliary high voltage generator output ±45 Volts

3 triple DACs 135 kHz for X, Y, and Z axis control, nominally 32 bit resolution, noise limit of < 1 ppm of full scale at the High Voltage Output.

For a MultiMode microscope using a 100 um scanner the voltage noise would translate to < 0.05 Å in Z and < 1 Å in X, Y.

Interface Board

The Interface boards are available now for the MultiMode™ and Dimension 3100 microscopes (Bruker). These boards connect from the original manufacturer standard interface connectors to our interface bus. This is designed to be easily adaptable. For Value Added Retail customers even the case can easily be changed to better match your products.


USB 2 interface to host computer (Gigabit Ethernet already implemented in hardware – future option)
