Psophometric analysis in the new OXYGEN 3.6 release

28/06/2019 | Knowledge, OXYGEN Software
Psophometric analysis is now an integral part of the new Oxygen 3.6 version.

Psophometric Analysis, Vector™ CAN(-FD), Swept-Sine Analysis, FGW-TG3 or IEC 61400-21 are terms you are familiar with? Have a quick look into our new features!

Just at the beginning of this great summer, we released a new version of our measurement application OXYGEN, OXYGEN 3.6. Therefore, we want to introduce the many improvements and new features that come along with it. Psophometric analysis and swept-sine analysis are only two of many new functions which will help you to easily get your work done, even with a smile. We’ll share all the hard work with you and everyone is invited to try the new OXYGEN version. If you love it, update it for free*!

Vector™ CAN(-FD)

With this new release of OXYGEN, we seamlessly integrate various numbers of Vector CAN(-FD) devices into your measurement app. First of all, this enables you to use common interfaces in addition to our approved TRION™ interface hardware within OXYGEN. In addition to that, we also support the receiving and decoding of CAN-FD messages as well as encoding and sending of measurement data. Now, we also officially support the Vector™ VN1610, VN1630A and VN1640A. If you want to use another model, please let us know and we will check the compatibility.

Swept-Sine Analysis

Are you interested in structure and modal analysis? Then we have the right solution for you. Together with our high-precision and high-density measurement hardware, we also offer the best solution for swept-sine analysis in modal identification. The easy-to-use concept as well as the precise results were two of our main goals when we designed this new calculation module. Due to that, we are convinced you will like it! Just these short steps are necessary:

  1. attach the measurement channels to the main unit
  2. assign the reference channel and all the acceleration channels
  3. optionally tune the input analysis parameters
  4. start the measurement and make a run, inspect the live values
  5. stop the measurement and consider the finished bode diagram

Psophometric Analysis

Finally, a second calculation module was born with OXYGEN 3.6. This module allows you to turn the DEWETRON system into a psophometer! A psophometer is an instrument that measures the perceptible noise of a telephone circuit. This is for instance used in railway applications to determine the influence of traction power to telecommunication circuits (EN 50121-3-1). In addition to that, it calculates RMS values and uses different weighting types (ITU-T O.41, flat, …).

Positive/Negative/Zero Sequence of Power

Similarly, we were also busy with the development of new features regarding the electrical power analysis. To support your work regarding the electrical compliance tests described in FGW-TG3 and IEC 61400-21, we now provide ready-to-use measurement data for your reports. Particularly, we do calculate the positive/negative and zero sequence of active and reactive power regarding the FGW-TG3 Annex F and IEC 61400-21 Annex C.

Needed for tests of grid compatibility of renewable energy generators like wind turbines

  • load drop
  • voltage drop or swell
  • reactive power drop and swell
  • LVRT testing

Automatic Export

We are very proud to introduce a probably small, but really important feature: the automatic export! This function allows you to configure OXYGEN to export selected channels in the desired format automatically at each stop of the measurement. This certainly increases convenience for your measurement tasks.

Math Formula – Update

Moreover, some of the basics got an update. There are new functions available that can be used within the Math Formula module. This time, we put the focus on measurement functions. In other words, we now enable even more calculations on conditions.

stopwatch Measure time in seconds between start and stop condition, with optional reset condition
measdiff Measure value difference between two conditions
period Measure the period duration in seconds between consecutive conditions with optional rearm level
dutycycle Measure the duty cycle (0-1) seconds between consecutive conditions with optional rearm level
edge Generate positive edge on cond with optional rearm level. Can be used in formulas with no rearm level
rmin, rmax, ravg, rrms, rsum, racrms, rp2p Rolling (min, max, avg, rms, sum, acrms, p2p) since measurement start with optional reset condition

Ethernet Receiver – now with Synchronization

Furthermore, the ethernet receiver learned to decode timestamps out of the data to synchronize the included payload to the measurement system’s time. As you know, also ethernet packages can be delayed at the origin or during transmission.  Therefore, when you use our ethernet receiver to decode UDP-packages as measurement channels, OXYGEN now offers the option to interpret a sub-packet as timestamp. The supported format is milliseconds since midnight. As a result, you can receive data from different sources with its special delays without any issues. After updating to OXYGEN 3.6, you can rearrange the data synchronously to each other and to the measurement system’s time base. In other words, this feature will facilitate your work a lot!

Additional Improvements

In addition to all the above mentioned functions, we improved several aspects of our OXYGEN to make it even more exhaustive:

  • extended compatibility of MSI-adapters in combination with CB-16-D
  • we allow now the simultaneous usage of XCP and SCPI
  • SCPI Update: gather channel information and add marker (see manual)
  • recorder instruments automatically links the time axis to directly adjacent other recorder
  • improved Channel List arrangement

In short, there are many new functions to explore!
