Significant Changes in R9s 3.0
Below is a summary of the significant software changes in R9s 3.0.
1. High Voltage Amplifiers: New options have been added including:
a. Output voltage limits of the HV Amplifiers now automatically scale the full range of the signal
connected to the amplifier's input to the limited output range. Previous versions clipped the voltage
output without scaling the signals.
b. Output limit settings have been simplified.
c. Sine and Cosine outputs of the internal NCO (Numerically Controlled Oscillator) can be digitally
summed into each HV Amplifier.
d. The Value of the R9 Controls connected to High Voltage Amplifiers are now displayed in physical
units of the output, such as 'nm', instead of volts.
2. Synchronization of Oscillators and Lock-in Amplifiers: Oscillation reference frequencies can be
configured graphically.
3. Dashboard Panels can be Minimized: The Dashboard Panels can now be minimized to the ribbon bar
In order to maximize the use of space. This is useful when a Panel is used infrequently, such as the
Current Input and Current Filter (in the case of STM).
4. Spectroscopy: The spectroscopy routines have been improved to allow bias modulation to be disabled
during topographic portions of measurements. Feedback loop parameters can now be separately set
for topographic imaging and to set tunnel gap resistance for spectroscopic measurements.
5. Piezo Sensitivity Selector: Up to four different temperature calibrations can be stored in an IHL file.
These calibrations can be changed when the controller is not initialized.
6. Z Position feedback indicator range can be automatically set from the Scan Area Window.
7. Scan Offset and Rotation buttons on the Scan Area Window have customizable behavior.
8. Automatic Startup and Shutdown Procedures: Added the ability to have a procedure automatically
launch after the software has been initialized and before the software has been shutdown.
9. Image Counter: Added a counter for the number of images scanned.
10. Dashboard controls, such as the PI Tip Control (freeze/retract/unlimit) are automatically updated
when changed by a procedure. Previously, these settings were not updated in the Dashboard when
changed by a Procedure.
11. Ramping a Dashboard Control will cause it to turn yellow for the duration of the ramping cycle (e.g. if
the bias voltage were ramped from 1 V to 5 V at a rate of 1 V/s, the bias field will turn yellow for the four
seconds during the ramp).
12. Custom Procedure Panels can now be added to Hardware Composites such that the controls and
input parameters appear on the Dashboard rather than having to go into the hardware space to change
them. This allows much greater flexibility for user configurable custom procedures.
13. Data Analysis (Browser) split into a separate program. The program is automatically assigned to a
separate processor core so processing large amounts of data will not interfere with the acquisition
software. Additionally, memory used in the image processing application is not shared with the data
acquisition application so more memory is available to each process.
