Significant Changes in R9s 5.2
1. Easier DAC1 Ramping: convert to physical units using the Scale tab, and using the Ramp Spec
Settings item with DAC1 allows for a more intuitive spectroscopy (e.g. ramping temperature in K). Ramp
settings allow Set, Linear, and AWG, as discussed above in the v5.0 release.
2. Atomic Manipulation in “Mini-Scans”: Often, users are interested to do spectroscopy (I-V or I-Z) at a
specific point on the scan area with some unique scan parameters. Having to do spectroscopy after
finishing the scan is not ideal, because any drift of the scanner will make it difficult to locate the exact
same point of interest in the scan area. Moreover, it is not very pleasant to change the scan parameters
(Bias, Scan Speed, Resolution, Set point etc.) between imaging and spectroscopy modes. This version of
the software has a new feature added to the Scan Area Window's Advanced Panel - Mini-Scans, which
makes it easier to perform Spectroscopy at any specific point of interest in the scan area. Mini-scan data
are stored in a separate file and when the Mini-Scan is finished, original imaging parameters are restored
for a seamless transition.
3. Doubled the Maximum Scan Speed.
4. Watchable F9, F11, and F12 hotkeys for Procedure Space: the IHL can be configured to dedicate F9,
F11, and F12 for user specific functions in the procedure space.
5. Data Logger: transients that are desirable to be monitored over a long time scale of say hours to days
can now conveniently be monitored from the R9 software through the Data Logger. An example might be
temperature. The sampling rate can vary between 0.1 Hz and 1000 Hz, and continuous acquisition can
ensue for a maximum of 5 days.
6. Spectroscopy Settings Tab Directly on Spec Windows Now: the settings can be saved with user-
specified file names as well.
7. Launch EXEs from Procedure Space: Any executable can be launched from the Procedure space
using the Run App item in IHL. Simple provide path to executable file and use the Run App item like any
other IHL item in procedures.
8. Record Status Channel in Data Page Header: parameters such as probe temperature, STM bias, or
any other quantity that won’t necessarily be changing continuously throughout the scans, can be recorded
once at the beginning of the image and stored in the header.
9. Transient Recorder FFT now Stand-Alone: the wide bandwidth (20 MHz) FFT can now be taken just
like a stand-alone spectrum analyzer. Single shot or continuous averaging are available, as well as
bandwidth, number of points to acquire, and scan mode are all included.
10. Custom Control Panels for Procedures: All Actions in the Procedure Space has a new Panel added
to the Properties menu. This Panel can be used to add features such as Edit box, Check box, Combo box
and Procedure button. Another interesting feature of the Panel is that the user can call out Procedures
within the Panel.
11. Removed External Hardware Items: To make the ADC channel recognize its true physical units,
previously an external hardware item was necessary that solely functioned for the purpose of changing
the units. Now there is a simple scale tab where this can be configured just as a parameter rather than a
