Mimea upgrade from BP3 to BP5e

Upgrading from a BP3 to a BP5e brings a massive performance increase and a vastly improved user interface. All relevant parameters have been improved by at least one order of magnitude. Moreover, the update ensures repairability and availability of spare parts.

Mimea BP5e hardware (RC5e, SC5)

Nanonis V3 SPM control systems were discontinued mid 2007 and reached their end of life in 2015. While many of these systems are still in operation, development at Nanonis hasn't stood still and the current generation of controllers is miles ahead both in performance and usability. Spare parts for V3 SPM control systems are no longer available, meaning that the V3 hardware cannot be replaced or repaired anymore.

The upgrade offers a straightforward path to current state of the art electronics and software, without requiring users to learn how to operate a completely different system.

Some of the benefits related to the upgrade: 

  • Flexible signal assignment with 128 live signals
  • Flexible signal handling, software modules have access to more signals
  • 64-bit software, more memory available for data buffering, more channels can be acquired simultaneously
  • Fast scanning and spectroscopy (up to 1.000.000 pixels per second) on up to 8 channels
  • Direct data streaming to disk with up to 1 Mpix/s on up to 8 channels simultaneously
  • Multi-pass improvements including possibility to write scripts running on the real-time system resulting in significant increase in speed and flexibility for advanced multi-pass experiments like KPFM
  • Letterbox scanning allows selecting two boundaries on the Y axis of the scan placed within the scan frame allowing the tip to be bounced within these two boundaries
  • Region of interest allows selecting a frame within the scan frame resulting in better tilt compensation for this sub-frame (e.g. on atomic terraces) or optimization of the colorscale only within the sub-frame
  • Improved safety for user inputs solves the difficulties encountered if you forget to use units when changing a parameter in the software
  • Improved “accessibility” of displayed data in graphs; functions of zooming, moving cursors and panning through a graph now accessible directly on the plot depending on the position of the mouse. Zooming can be done using the scroll wheel
  • Multiple past function including management of several background images in the scan control module
  • New oscilloscope with two channels instead of one, enhanced triggering and display options, with high resultion high speed oscilloscope/FFT add-on option with up to 1 million points per trace (user selectable), 1 MS/s sampling rate, 100 kHz analog bandwidth
  • New programming interface add-on with LabVIEW and a generic script-language TCP-interface
  • New and completely different lock-in add-on with advanced signal filtering, tandem-demodulation, multi-frequency and multi-input options, up to 8 independent synchronizable modules, guided filter set-up utility
  • New multi excitation add-on module for Q-control, dual- and multi-frequency excitation schemes, amplitude modulation, Sideband detection
  • Possibility to extend hardware to up to 40 analog outputs and 24 analog inputs
  • Simple extension to the multiprobe control system
  • Simple extension to Nanonis Tramea for quantum transport measurements

Compatible instruments: 

  • RTPC (19" rack-mount)
  • First generation PXI-based real-time controller

Not compatible for this upgrade:

  • RC4

The upgrade includes:

  • Replacement (trade-in) of PXI controller and SCCB, RTPC and SCCB with a discounted BP5e

The OCB oscillation controller also needs to be replaced (AFM systems only). High-voltage amplifiers and adaptation kits can be reused.

EOL information for V3 systems:

The following discontinued V3 instrument models have reached their end-of-life and no repair service or support will be provided anymore:

  • RTPC (19" rack-mount)
  • First generation PXI-based real-time controller

In case of hardware failure the instruments need to be replaced by an instrument of the currently available product line.

The following discontinued V3 instrument models have reached their end-of-life and repairs cannot be guaranteed anymore:

  • All 19" rack-mounted instruments except RTPC

In case of hardware failure the instruments might need to be replaced by an instrument of the currently available product line.


  • Replacement of the V3 base package with a current generation V5e base package
  • Massive performance increase
  • Significant amount of new features and measurement modes
  • Largely upgraded user interface
  • Repairability and spare parts guaranteed for the lifetime of the new system
