VirtualBench Firmware Release Notes

Windows application changes:

• Fixed application crash when opening WiFi dialog—the VirtualBench device cannot recognize EAP-FAST (802.11r) networks and previously would crash the application when it detected one (IDs 635444, 702623). 
• Fixed application crash when the host uses FIPS—previously the application would crash when the host required the use of FIPS-compliant hashing algorithms (ID 712620). 
• Fixed application crash on launch—previously the application could crash on launch when it tried to report an internal error or warning to NI's telemetry server (ID 718317). 

Windows application changes:

• KRACK WiFi Security Vulnerability patch to address the security vulnerability that allows a potential attacker to execute a Key Reinstallation Attack ("KRACK"). This update is highly recommended to prevent unwanted access to user data. 
   

For detailed information, go to ni.com/info and enter KRACKWiFi2017Q4 for more information.      

Windows application changes:

• Support for new VirtualBench hardware: New hardware includes a 4 channel, 2 GS/s oscilloscope with 500 MHz bandwidth
• DC Power Supply bug fixes
• Improved signal representation
• Several example arbitrary waveforms including AM and FM waveforms

Windows application changes:

• Added XY Mode: Plot one channel against another to aid in IV curve characterization and plotting Lissajous patterns.
• Added Hands-Free Smart Capture: Allows for the automatic data capture of repeated stable waveforms on the oscilloscope. 
• Added Measurement Indicators: View location indicators on the graph to better visualize where a measurement is being taken.

This update is critical as it could potentially affect measurement accuracy.

• Bug fixes to the DC Power Supply to improve accuracy
• Added protection on the function generator from overvoltage conditions outside of specifications
• Fan algorithm updated to ensure specification under a wider range of ambient temperatures. 

Windows application changes:

• Added Reference Waveforms: Save a captured waveform and recall it later. (VB-8012 and VB-8034)
• Added Arb from File: Load an arbitrary waveform file (*.txt, *.csv) in the app to output on the function generator. (VB-8012 and VB-8034)
• Added a Pulse Width Trigger for analog or digital signals. (VB-8012 and VB-8034)
• Added additional FFT windowing options. (VB-8012 and VB-8034)
• Added Digital Phosphor: Display many acquisitions simultaneously with a density map of voltage over time. (VB-8034)

Windows application changes:

• Added Monitor Mode: watch instruments automated in LabVIEW or C.
• Added cursors for decoded buses.
• Added 20 MHz bandwidth filter setting to MSO analog channels.
• Added light theme.
• Added Russian support.

Device API changes:

• Fixed the function generator API to now return an error, rather than a warning, when you specify a combination of amplitude and offset that results in exceeding the +/- 12 V output range (ID 516309).

• No Windows application changes
• Device API changes: added calibration and adjustment support . Refer to the NI VirtualBench Calibration Procedure.

Windows application changes:

• Added support for French, German, Japanese, Korean, and Simplified Chinese.

Windows application changes:

• Added digital buses. Group mixed-signal oscilloscope digital channels into buses.
• Added protocol analyzer. Decode SPI, I2C, and parallel protocols with the mixed-signal oscilloscope.
• Added custom digital thresholds. Configure logic thresholds for mixed-signal oscilloscope digital channels.
• Added division function to the mixed-signal oscilloscope math channel.
• Fixed several documentation inaccuracies.
• Fixed application crash when launched from Windows guest accounts (ID 478850).
• Fixed application hang when resuming from sleep (ID 438124).
• Fixed missing units, dB reference, and f0 in exported FFT data (ID 455787).
• Stopped instruments when a screenshot or data is saved (ID 437632).
• Added missing tooltips (ID 489543).
• Fixed missing pulses at high frequencies and low duty cycles for square waves (ID 474534).
• Fixed glitch when changing between square and sine waveforms (ID 460783).

Device API changes:

• Added C API.
• Added serial protocol mastering. Master SPI and I2C protocols with the digital I/O.
• Added 20MHz Bandwidth limit filter. Remove unwanted high frequency noise from your signal.
• Added PowerFreq and FGEN Start terminals to LabVIEW IO control (ID 425355).

• Added an FFT Math operation (Windows).
• Fixed bug related to exporting data and screenshots. (ID 473341)
• Fixed bug related to zooming on stopped data. (ID 469784)
• Fixed bug related to the cursors overlapping the trigger position. (ID 461001)
