Mobile Oscilloscope vs IEC61850browser

This application turns your phone into a powerful handheld oscilloscope for audio signal analysis (professionals can also use for circuit analysis). The signal parameters can be displayed in detail, including: maximum value, minimum value, average value, effective value and frequency, and the frequency measurement is very accurate. There are multiple trigger modes. The trigger modes are: automatic mode, normal trigger and single trigger; the trigger edges are: rising edge trigger, falling edge trigger, rising or falling edge trigger, jump trigger and differential trigger; the trigger value can be selected. With the measurement function, it is freely measured in the horizontal and vertical directions, gesture operation, easy to use. Waveforms can be freely zoomed with gestures or buttons. Supports interface color selection. Has a storage depth of 10 seconds. This application is normally used for audio signal measurement without any risk. Circuit measurement special instructions: Professionals can use this application for circuit measurements and the electrical signal is input via the microphone channel of the headset. Please pay attention to safety: You must have enough professional knowledge. The high voltage circuit must go through the isolator and attenuator. Conventional low-voltage circuits must also add an attenuator and then enter the phone. Circuit measurement is risky and the author of this application will not be liable for any loss of personnel or equipment resulting from the correct or incorrect use of this application.

The IEC 61850 Browser is a mobile diagnostic and control tool for IEC 61850-based protection and control devices (IEDs), developed for professional use in the field. The app supports direct connections to IEDs as well as automatic device discovery through an integrated network scanner. Via the USB-C interface, Ethernet-to-USB-C adapters can be connected and configured as the primary network interface, ensuring that all IEC 61850 communication is routed exclusively through the selected port. Once connected, the app automatically reads the complete IEC 61850 data model from the IED and displays it in a clear, structured hierarchy. Users can query individual or multiple data objects at the same time and monitor live values. For each retrieved value, the app displays: • Value • Quality information • Timestamp The app supports both time-based polling and report-based monitoring. Depending on the capabilities of the connected IED, users can monitor live process data either by cyclic polling or by subscribing to IEC 61850 reports for efficient event-driven updates. An integrated Event Log is available for both monitoring modes. Recorded events can be exported in TXT or CSV format for documentation and further analysis. The app also supports sending control commands to IEDs. If a command is rejected, detailed feedback is provided, including the reason for rejection. Cybersecurity features are also supported for protected IED connections. Depending on the device manufacturer and configuration, users can authenticate either with a password only or with a combination of username and password. If supported by the connected IED, disturbance records can also be accessed and read via file transfer. The IEC 61850 Browser can generate and export IEC 61850 CID and IID files based on the connected IED. Exported files can be used for engineering, documentation, and interoperability purposes. Exported CID/IID files and recorded Event Logs are stored locally within the app, allowing users to access, review, and export them again at any time without reconnecting to the IED. The app also includes an integrated time server that can synchronize the time of supported IEDs directly from the mobile device, simplifying commissioning and maintenance tasks. For continuous monitoring, the app includes an option in Settings to prevent the device display from turning off while the app is in use. This helps avoid automatic device locking and potential connection interruptions during longer monitoring sessions. The IEC 61850 Browser is under continuous development, with more features planned for future releases. The app includes a 7-day free trial with full functionality. After the trial period, continued access is available through an annual subscription. Compatible with iOS and iPadOS 17.8 or later.
