RELEASE NOTES HF2 SERIES SOFTWARE 11.02 ======================================= Zurich Instruments AG, April 2011 http://www.zhinst.com CONTENTS ======== 1. Notes 2. Driver Installation 3. HF2 Release History Summary of Changes 11.02.1 Summary of Changes 10.06.1 Summary of Changes 10.06 Summary of Changes 10.03 1. NOTES ======== The V11.02 release is a feature and a bug-fix release. Updating is strongly recommended. The V11.02 release includes stability relevant bug fixes. 2. DRIVER INSTALLATION ====================== When prompted by Windows for driver installation, tell Windows to _not_ look on "Windows Update" for new drivers and tell it to "automatically install drivers". Windows XP: Please ensure that you have installed the Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update using Windowsupdate (there you will find it under software, optional). Update LabVIEW driver It is important to update the LabVIEW driver. The old API will not work with the new ziBase. After updating ziControl, you will find a new version of the LabVIEW API in C:\Program Files\Zurich Instruments\API\labview\driver.zip. Extract the contained folder "Zurich Instruments" to C:\Program Files\National Instruments\Labview 2009\inst.lib\ and restart LabVIEW. 3. HF2 Release History ====================== Legend: + Added feature * Improved/changed feature - Bug fixed ! Known issue / missing feature SUMMARY OF CHANGES 11.02 ======================== General + Added sinc filter to eliminate omega and 2-omega components + Added support for PID option + Added support for rectangular output waveform - Minor bug fixes in ziServer and ziControl * Increased cumulated demodulator sample rate to up to 700kS/s ! Sample loss may occur for sample rates >25kS/s when scope is active. Sample loss is correctly indicated. ziControl + Added Zoom FFT * Improved RT interface * Improved frequency sweeper * Improved Save function includes a descriptive text file and a png file of plots * Log now has a browseable history API + Added flush command + Added LabVIEW vi's for measuring impedance + Added support for Matlab + Added support for Python 2.6 PLL Option - 2-omega mode for PLL. Fixed * Improved PLL Advisor * Improved PLL Settings PID Option ! PID Advisor is missing RT Option * Increased RT processor speed by factor of 4 * Increased the number of available user registers to 64 * Added installer script to RTK software SUMMARY OF CHANGES 10.06.1 ========================== General + added support for HF2TA current amplifier - Minor bug fixes in ziServer and ziControl - Fixed issue with default settings in HF2IS ziControl * Improved sweeper + Added noise measurement API * Improved stability with high data rates PLL Option * Improved responsivness of interface ! 2-omega mode for PLL does not work MOD Option - Readout is now set correctly SUMMARY OF CHANGES 10.06 ======================== General + DIO triggering of demod samples now either on edge or gated on level * sign of theta changed ziControl * ziControl increased usability by improved GUI + ziControl now memorizes the last 10 hosts it connected to + Aux Outputs: autozero function to adjust Offset such that the output becomes 0 + spectral density units for Oscilloscope FFT + Log/Lin Frequency mapping for Oscilloscope FFT - wrong RMS averaging in Oscilloscope FFT. Fixed. - Aux Outputs: wrong indicator for demodulator selector at startup. Fixed. API + Added Utility/ziSweepUnitConversion.vi to convert sweeper results to spectral density units + Added Utility/ziTC2ENBW.vi * ziSweep now allows for sweeping multiple demods. This facilitates 4-point measurements * The timestamp is now passed as an unsigned 64-bit integer. To convert the timestamp to seconds the function ziAPISecondsTimeStamp has been added. ziServer * "kits" node is renamed to "options" * Demodulators now have a "trigger" node to configure sample triggering and gating * Demodulator "rate" is now rounded up and down instead of always rounding up * IS-Demodulators now have and "oscselect" node to choose the source oscillator * PLL node now allows a negative value for "pgain" - The count of enables and amplitudes in sigout now corresponds to the count actually available - The frequency of IS-demodulators 7 and 8 is now displayed and stored correctly RT Option - the UHS option is now also returned when calling ziRTKFeaturesGetOptions + external memory is now also accessible by the user, use ziRTKExtMemGet and ziRTKExtMemSet SUMMARY OF CHANGES 10.03 ======================== General + Synchronous enabling of outputs at zero crossing + External lock on signal on DIO and Aux Inputs + DIO values are recorded synchronously with Demodulator data * Trigger readout by TTL signals on DIO inputs. ziControl + Support of Dual PLL Option + Support of AM/FM Modulation Option + Auto-range for signal inputs * Various enhancements in the graphical user interface * Increased flexibility in choice of signals in Spectroscope view * Display values of Aux outputs. * Auto-zero phase also works when working with internal signal generator (phase shifts do not affect outputs) * Oscilloscope: Averaging for FFT - Save Data is loosing data. Fixed. - Load/Save HF2 config misbehaves. Fixed. ! Under heavy system load, the Spectroscope View is loosing data. This only affects visualization. ! With more than 1 HF2 device connected to the PC, ziControl will reconnect when a second ziHF2 is connected or disconnected to the PC. API * New LabVIEW example vi's * New LabVIEW API vi's: TC2BW, BW2TC ziServer * Increased stability of ziServer - Stability issues when using several HF2 simultaneously - Stability issues during startup RT Option * Increased clock frequency of real-time processor to 64 MHz * Real-time processor can access 64 MB DDR Ram
