Release Notes for Nanonis SPM V5 Software

New advanced features in the Lock-In module (option to generate an output signal in sync with a frequency generator and option to use the demodulators as configurable filters for any signal)
Added Offset for Input channel in Temperature modules
Fix for progress bar in Bias Spectroscopy
Fix for Outputs channels of SC5 #2/#3 or SO5
Fix for high RT CPU load in certain systems which might create connection issues (especially important for users of older RC5 with NI PXIe-8115 Real-Time Controllers, where the CPU of the RT system could easily overload)
Some minor changes

Z-Controller SafeTip Auto-Recovery now also works when the Z-Controller is switched off.
Bugfix for PLL #2
Programming Interface: Added function to return the Z-Controller status (more details than just on/off)
Various minor changes and fixes

Performance improvements Real-time system (especially important for users of older RC5 with NI PXIe-8115 Real-Time Controllers, where the CPU of the RT system could easily overload)
Performance improvements for some TCP Programming Interface functions
TCP Programming Interface changed to allow multiple connections, each of them executing the commands serially. To execute commands in parallel, use multiple connections.
Callback VI section in Multipass available to all users
Added ports C&D to the DIO Trigger experiment
Support for new Programming Interface functions (e.g. stop PLL sweepers and Tip Shaper)
Various other fixes and improvements

Scan Control: 3 new DIO trigger options for frame start, frame end, scan direction
Better support for systems with unipolar piezo outputs
Lock-in: can now demodulate all FPGA signals. Possible application: tandem demodulation (demodulate the output of another demodulator)
Lock-in demodulators can be used as generic low-pass filters by setting harmonic to 0
Various new functions in the Programming Interface / TCP Interface
Many other fixes and improvements

Switchable Scanner: optional module to switch the scan control between 2 scanners (one can be scanned, the other is kept at the current position)
Support for DIO Ports C & D added
New Attocube Motor Control for ANC350 v4
New motor module with 1 TTL line fully configurable
Cloud mode was improved to allow more points and massive better performance for point manipulation
Piezo Calibration: new voltage limits per calibration profile

Full support for up to 3 SC5 and 2 SO5 (maximum of 4 devices total), i.e. the additional devices are supported in hrDAC (only SC5), Lock-in, Function Generator, High-Resolution Oscilloscope.
Output/Input modules (for devices above SC5 #1): added custom views, which lets the user define groups of up to 8 outputs/inputs to be visible in addition to the standard view of channels per device.
Oscillation Control: flexible modulator configuration, allowing modes like Q-Control or dual excitation (using a single OC4).
Bugfix: On systems with comma (,) as decimal separator, the ZoomFFT module would incorrectly interpret the cutoff frequency and thus not work correctly for some cutoff frequency settings.
Many other fixes and improvements

Performance optimizations in the software. When operating the software for a long time software operation could become sluggish. This update should improve the performance.
Bias Spectroscopy: added option to use an alternate Z-Controller setpoint before starting the spectroscopy measurement and added option to switch the lock-in on/off per segment in multi-line segment measurements. Also added an initial delay per segment to let the lock-in signals settle.
Z Spectroscopy: added 2nd condition to the Auto-Retract functionality
Script module: added new commands (if, break)
Scripts can now be called from the Scan module in pattern or subgrid modes. Several fixes in the Script module, e.g. related to LUT.
Fixed bug in Z-Spectroscopy which added one RT cycle per point with a specific timing configuration
Fixed bug in Scan Multipass where list of channels available for recording was wrong
For users of R7232 we strongly recommend this update due to a hrDAC issue for AO1 in R7232 which could lead to glitches at the output, and due to a bug using the Lock-In in Bias Specroscopy

Support for up to 3 SC5's, providing up to additional 16 output and 16 input channels
Script module: improved user interface with easier access to commands and drag&drop capability
AtomTracking controller: Added speed limit for tip movement
Fixes a bug that could lead to a "Memory is full" error when using Bias Spectroscopy
Fixes a bug in the Lock-in low-pass filter configuration
Several other fixes and improvements

Lock-In: second module with one additional modulator and two more demodulators
Programming Interface functions for full Lock-in functionality added (including filter settings and other parameters)
Data Logger: new module to continuously save data to disk at RT speed
Script module: new features like the option to wait for a digital line or edge, and to set voltages based on a lookup table
History graph: new auto-saving routine
Support for new generation of RC5 controller (NI PXIe-8840 RT)
Note: after installing the RT-Upgrade required for this version, no previous versions can be installed
Various fixes and minor improvements

Lock-In: all new Lock-in module with configurable filters (high-pass, low-pass, sync) and delay compensation
Scripting Tool: new module allowing the execution of user-defined scripts directly on the Real-time engine
Programming Interface: some new functions added
Various minor improvements

Frequency Sweep: new amplitude and phase fit options for resonance frequency and Q-factor determination
Generic PI Controller can now be assigned to any User Output
Programming Interface: added access to advanced options in Bias- and Z-Spectroscopy functions
Non-working mouse behavior on the Scan Control image on some systems fixed
Move button failure in Motor Controls PMD, Omicron and Newport fixed
Various other fixes and minor improvements
