It allows you to calculate statistical values based on a defined number of signal periods, providing more meaningful insights for periodic signals. Key configurations include:<\/p>\n<ul>\n<li>The selection of the period source channel, which by default is identical to the statistics input channel but can be reassigned<\/li>\n<li>The definition of the number of periods used for analysis, ranging from 1 to 1000 periods<\/li>\n<li>Configurable trigger settings for reliable periodicity detection<\/li>\n<\/ul>\n<p>In addition to all standard statistical quantities, Phase-Locked Statistics also introduces two new statistical values:<\/p>\n<ul>\n<li><em>Frequency<\/em>: frequency of the analyzed periods<\/li>\n<li><em>Period time<\/em>: duration of a single period<\/li>\n<\/ul>\n<p>Together, these enhancements improve the analysis of periodic signals, resulting in more stable, meaningful, and application-oriented results.<\/p>\n<p>&nbsp;<\/p>\n<h3><a name=\"_Toc228809531\"><\/a>Extensions for DEWE3-OPT-DIO\u2018s Digital Outputs<\/h3>\n<p>With this release, we\u2019ve enhanced the Digital Output capabilities of the DEWE3-OPT-DIO option on Chassis Controllers, enabling greater flexibility for synchronization, triggering, and signal distribution.<\/p>\n<p>In addition to the standard Digital Out mode, Digital Output channels now support the following signal types:<\/p>\n<ul>\n<li><em>FrequencyClock<\/em> \u2013 Continuous clock signal from 1 Hz up to 10 MHz<\/li>\n<li><em>PPS<\/em> (Pulse Per Second) \u2013 One pulse per second<\/li>\n<li><em>CLK10<\/em> \u2013 Dedicated 10 MHz continuous clock signal<\/li>\n<li><em>IRIG<\/em> \u2013 Pass-through of an IRIG-B signal when used as sync output<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.dewetron.com\/app\/uploads\/2026\/05\/DO-scaled.png\" width=\"750\" \/><\/p>\n<p style=\"text-align: center;\"><em>Fig. 5: Extensions for DEWE3-OPT-DIO\u2018s Digital Outputs<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>Further, the AUX output pin is now available as a software channel. This virtual channel represents the physical <em>Synchronization Output Connector \u201cAUX\u201d<\/em> and provides access to the same operating modes: <em>PPS<\/em>, <em>FrequencyClock<\/em>, <em>IRIG<\/em>. Any changes applied to this software channel are directly reflected in the SYNC Out settings. Additionally, the mode <em>CustomSignalOut<\/em> enables you to forward the configured synchronization signal from the AUX connector. This allows monitoring the Sync Out signal directly as a channel and distributing it to any other Digital Output channels (on the Chassis Controller).<\/p>\n<p>&nbsp;<\/p>\n<h5>Notes:<\/h5>\n<p>&#8211; Requires <strong>TRION-API<\/strong> and <strong>firmware<\/strong> update (not just an OXYGEN update)<br \/>\n&#8211; Requires software option <strong>DEWE3-OPT-DIO<\/strong><\/p>\n<p>&nbsp;<\/p>\n<h3><a name=\"_Toc228809532\"><\/a>Usability Updates and Refinements<\/h3>\n<p>In addition to the major feature enhancements, OXYGEN 8.1 introduces several smaller improvements that further refine usability and system flexibility.<\/p>\n<p>&nbsp;<\/p>\n<h5>CAN-OUT &#8211; Averaging Skipped Output Channels<\/h5>\n<p>The CAN transmission settings now include a new Output Mode option. When set to <em>Average<\/em> (default), a block-wise linear average is calculated and output for all samples within the defined output period. Alternatively, selecting <em>Last_Value<\/em> restores the previous behavior, where only the last valid sample is transmitted.<\/p>\n<p>&nbsp;<\/p>\n<h5>Resolver Plugin \u2013 Smoothed Speed Output<\/h5>\n<p>To improve signal quality, a running statistics filter with a definable filter length (1-1000 ms) is now available in the resolver plugin. This allows smoothing of the speed output signal, resulting in more stable and reliable measurements.<\/p>\n<p>&nbsp;<\/p>\n<h5>Quick Access to Favorite Calculations<\/h5>\n<p>Your first four favorites from the <em>Add Channel<\/em> menu are now displayed directly at the bottom of the channel list.

This enables simultaneous use of tools such as <a href=\"https:\/\/www.dewetron.com\/cn\/products\/software\/oxygen-go-app\/\">OXYGEN-GO<\/a> alongside SCPI-based remote systems, allowing for more flexible and advanced test setups.<\/p>\n<p>&nbsp;<\/p>\n<h3><a name=\"_Toc228809533\"><\/a>OXYGEN-SDK \u2013 Python Support<\/h3>\n<p>In addition to the above-mentioned OXYGEN feature updates, we have significantly expanded the <a href=\"https:\/\/www.dewetron.com\/cn\/products\/software\/oxygen-sdk\/\">OXYGEN-SDK<\/a> (ODK) by introducing Python support. This allows you to develop custom software channels in Python, similar to what is possible with the C++-based ODK.<\/p>\n<p>With this addition, you can register new channel types directly in the <em>Add Channel<\/em> dialog, create output channels with custom properties, and fully customize both the Add Channel and Channel Details pages using QML. Localization is also supported, enabling translation of property names and user interface texts.<\/p>\n<p>From a technical perspective, Python plugins run in their own dedicated process to ensure the stability of OXYGEN. They can either be started automatically by OXYGEN or executed manually within a debugger, which simplifies development and testing workflows. The implementation supports Python versions 3.12 to 3.15 as well as NumPy 2.x, providing access to a modern scientific computing stack. For further details and practical examples, please refer to our GitHub repository.<\/p>\n<p>&nbsp;<\/p>\n<h5>Note:<\/h5>\n<p>While Python offers greater flexibility and ease of development, it is important to note that performance will be lower compared to a comparable C++ plugin. This is due to the Python interpreter, multithreading limitations, and additional data transfer overhead.<\/p>\n<p>&nbsp;<\/p>\n\n          <\/div>\n        <\/div>\n          <\/div>\n  <\/div>\n<\/div>\n\n\n<div id=\"\" class=\"wp-block-claim-links-gray margin-bottom-none\">\n  <div class=\"container-fluid bg-container py-7 bg-darkgray\">\n    <div class=\"container position-relative\">\n      <div class=\"claim col-12 col-lg-8 offset-lg-2 text-center text-light\">\n                  <h3 class=\"h3 text-uppercase\">TRY OXYGEN RIGHT NOW!<\/h3>\n                          <h4 class=\"mb-0\">\n            If you are already a DEWETRON customer and now want to test our new updates, go to our Customer Care Center (CCC) and download OXYGEN 8.1.
