Significant Changes in R9s 5.0
1. Inventor SDK: this feature enables the user to control R9 with text commands sent over Ethernet to
the R9 software. Any application can be used to send the commands, for example LabVIEW, Matlab,
C/C++/C#, Python, Java, etc.
2. Drift Correction: both automatic and manual modes are possible. The cross-correlation is computed
for a defined reference area and the software calculates the vector of drift and can update it dynamically
or between images. Alternatively the user can override this and put in the vector manually. More on drift
correction is available below.
3. Mode Switching: toggling AFM feedback modalities (e.g. tapping, non-contact, contact, dissipation)
can now be done from the command ribbon. Previously the IHL would need to be shut down, a different
channel from the PLL would route to the Z-PI controller in the FPGA space, and then it would be
necessary to re-initialize. Now a selector is present in the Z-PI FPGA item, which can be selected from
the Dashboard. Note that there are procedures associated with each feedback type that must be merged
with the IHL in order for this feature to run. Memory of the P and I gains is ported back and forth as
modes are switched, which prevents unsafe gains applied to piezo elements, and it is also very
convenient.
4. Tip Motion Bug Fixed: please contact RHK support as Procedures also need to be upgraded to
eliminate the bug.
5. Data Channels have User Configurable Names: a Use Auto Name option, which is enabled by
default, can be unchecked and this allows the user to name the channel to their preference. Confusing
automated hardware space connections can now be avoided.
6. Tip Standby – Current Position: when Stop button is pressed, the tip can now stay in its current
position. Previous options of Image Center, Scanner Zero, and Image Start are also still available as
well.
7. User-Specified Max/Min Ranges on Parameters: The user can directly put upper and lower limits on a
value to ensure safe operation. For example placing an upper limit on the feedback gain to avoid
damage to piezo elements, or setting a negative gain, which would invert the feedback. Natively R9 does
not restrict the user from putting in any value, but this provided the option for a safety measure.
8. Load Images from File Browser on Scan Area Window: While in the file browser, any image can be
right-clicked and sent to the SAW by selecting Load SM4 in SAW.
9. Change Scan Size on the Fly: we can now change the scan size during image acquisition. The size
change will take effect on the next scan line. The SAW will still display the image over the original size,
but the image windows will reflect the updated scan size.
10. Slope Compensation Controls are now as Percentage: rather than having a value from -1.000 to
1.000, a more intuitive control is to have it as a percentage for the slope.
11. Added minus Z-scan Input to the Piezo Tube Item: this allows for higher flexibility for special case
scan heads.
