Product support changes for BK Connect:

Microsoft .NET 7.0, previously used in Team Server, is now out of support. Therefore, Team Server has been upgraded to use .NET 8.0 to ensure continued performance, security, and stability.

The updated Team Server installer will automatically install .NET 8.0 on your machine, if it is not already present.

We highly recommend that all Team Server users upgrade to the latest version.

Thank you for your attention and continued support.

Plotting your own parametric reference curve

BK-Connect-- Parametric-reference-curve-1

In BK Connect 2024.0, reference data defined from measurement data were introduced. This addition meant that you can compare measurement results against a selected reference curve to perform benchmarking, diagnostics or averaging.

Now in version 2024.1, you can do more with reference data: Create FFT curves as you perform measurements and analyses to compare and validate that results are within specific limits or tolerances, for example when running standards-based testing.

You define the parameters including the number of FFT lines, the frequency span, format and interpolation, then plot the FFT curve. You can preview the generation of the curve as you add data points to it.
The generated reference curve is immediately available to use during both measurement and post-processing to visually compare and validate your measurement results.

Added Support for Data Acquisition with Fusion-LN DAQ Hardware

Fusion-LN 3070-A-060 front view

Fusion-LN DAQ hardware covers a range of devices that are extremely flexible and can be easily reconfigured as requirements demand, with different connectors using interchangeable front panels. The same device can be used stand-alone in the field with a DC power supply as well as part of a distributed or semi-distributed measurement system with power over Ethernet (PoE).

The first available module is 6-channel 102.4 kHz Input Module Type 3070-A-060, a single-module full measurement system with signal conditioning, data acquisition and network connection.

When compared to LAN-XI, Fusion-LN modules have double the bandwidth, and complies with openDAQ™. For sustained productivity with your current system and a seamless transition to future systems, Fusion-LN is designed with co-existence and backwards compatibility in mind. Devices can be integrated in a distributed system with LAN-XI devices and a ‘Compatibility mode’ option that you can switch on within Fusion-LN, enables you to stream to older versions of BK Connect and LabShop.

  • Reference curves can be in viewed in all pretest and measurement tasks

  • Improvements to Fast Displays:

    • Right-clicking the Y-axis in a Fast Display, you can select: Autoscale this, Autoscale unit or Autoscale all

    • Double-clicking the X-axis (time, frequency) autoscales to the minimum and maximum values available

    • Pressing the button while double-clicking the X-axis (time, frequency) autoscales to nearest round numbers based on the unit setting

  • Added Autoscaling All button for time traces in the Monitor's display toolbar, allowing you to quickly apply autoscaling

  • In the Test-based Viewer (Data Processing and Modal Analysis), you can define how and what you want to view using the new Layout, Show Reference Data and Compare Data buttons

  • The functionality previously only available in a Type 8400 B license has now been moved to the base Data Viewer Type 8400 license. This means you only need Type 8400 for:

  • File import of any format used natively by HBK applications, as well as universal files: *.unv, *.uff (time and function data) and wave files: *.wav (time data)

    • Import from LabShop and Import from PULSE Data Manager (PDM) tasks

    • Export to PDM

    • Export to Excel

  • The maximum number of LAN-XI modules that are supported with a Type 8401 license is increased from 2 to 5. As always, two Type 8401 licenses can be stacked together to provide unlimited module access.

  • Improved support for hydrophone calibration.

  • Improved notifications and additional alerts when there are problems loading hardware setups

  • Order Analysis Applet Type 8490-B-N-SYS now supports non-stationary order tracking vs time.

  • The Measurement Matrix in the Standard Measurement task has been revamped giving you a more user-friendly and efficient interface.

  • Improved stability in CPB processing with more consistent linear results.

  • Validate and compare your results as you test with Test-based Viewer.

  • Minor improvements and enhancements including the averaging of FRF measurements in the Record and Process task.

  • Order analysis is now under one license: Type 8405 E.

  • Expanded support of tonal metrics standards for sound quality evaluations using the SQ Metrics and SQ Metrics vs Time process chain elements. Additional support for:

    • DIN 45681 Berichtigung 2:2006-08

    • ISO/TS 20065:2022

    • ISO 1996-2:2017

    • ECMA-418-2

  • Support for NVH models in the ATFX file importer.

  • Support for tyre noise correction according to ISO 362-3:2022, which is the 4-coefficient method, instead of 5, and uses air temperature for corrections.

  • CSV export for any analyzed additional signals, in addition to the pass-by signals.

  • A user-defined high-pass filter is now available for pre-processing of time signals for shock response spectrum (SRS) calculation in the Shock Response Analysis application.

  • The Measurement Matrix in the Hammer, Shaker and Stepped Sine Setup and Measurement tasks has been revamped giving you a more user-friendly and efficient interface.

  • Swept sine measurement implemented in the Shaker Setup and Shaker Measurement tasks.

  • Validate and compare your results as you test with the Test-based Viewer in the Modal Analysis application.

  • DOF selection and deselection in a mode table is now reflected in the animation and in the calculated MAC and orthogonality plots and tables.

  • A warning is now shown if a wrong camera driver is used.

  • Support for uEye® camera version 4.96.1

  • Scaling information has been added to exported WAV files
