Two Wi-Fi oscilloscopes perform wireless measurements
TiePie has introduced the WiFiScope oscilloscopes which can be used via an Ethernet connection (LAN, Wi-Fi or WAN) but also still with a USB 2.0 or USB 3.0 connection. The built-in battery allows the WiFiScope the possibility to perform fully wireless measurements which can be performed completely galvanically isolated and over long distances. The wireless PC-based data acquisition instrument can perform measurements around the world via a WAN connection. Specific knowledge on networks is not required, says TiePie.
Combined with the MultiChannel oscilloscope software, the WiFiScope WS6 and WiFiScope WS5 a PC into a high resolution oscilloscope, precision spectrum analyser, high performance multimeter, very fast data logger and comprehensive protocol analyser. The MultiChannel software gives an overview of the available USB instruments and network instruments. Users can simply tick the instrument to start measuring.
Mobile measurements can also be performed, on transport systems and moving installations. LAN and WAN data acquisition is available for long distance measurements and continuous, real-time, high speed data acquisition over both Wi-Fi and LAN/WAN are available.
USB measurements for standalone applications and high speed data acquisition are up to 200Msamples per second.
The WiFiScope is so transparent that it appears that the Ethernet connected instrument is connected directly to the computer, explains TiePie.
All hardware and software functions of the oscilloscope, spectrum analyser, data logger and voltmeter remain available via the network.
Wi-Fi and LAN/WAN instruments can allow users to make long-distance measurements, measurements at unsafe or noisy places, measurements at a moving installation or reading instruments at different places are now available.
The Wi-Fi oscilloscope provides high speed, real-time continuous data acquisition rates of 5Msamples per second can be achieved with a resolution of 8- to 16-bits and, via LAN/WAN connections, high speed real-time continuous data acquisition rates of 20Msamples per second can be achieved with a resolution of 8- to 16 bits. High speed, real-time continuous data acquisition rates of 200Msamples per second can be achieved with the same resolution via USB connections.
TiePie points out that the WiFiScopes ensure that no ground loops can occur. In traditional measurement systems, ground loops can result in unreliable measurement results. According to TiePie, long distance remote measurements are possible without the results being influenced by ground loops and on short distances the absence of ground loops is important for performing reliable measurements. The WiFiScope prevents ground loops from forming so that the measurement speed and resolution are not affected and the measurements remain reliable.
A software development kit supports users writing PC-based data acquisition software, and has examples in C, C++, C#, Python, Matlab, Node.js and Visual Basic.NET. Own written data acquisition software for the Handyscope HS5 and
Handyscope HS6 DIFF can be used directly for the WiFiScope WS5 and WiFiScope WS6. Developing the software for a USB data acquisition system or a wireless high speed WiFi data acquisition system makes no difference and the developed software can be used transparently.
