TiePie engineering WiFiScope WS6 DIFF and WiFiScope WS4 DIFF oscilloscopes

Posted on by mixos

TiePie engineering has introduced two new members of the powerful high resolution WiFiScope series oscilloscopes, the WiFiScope WS6 DIFF and WiFiScope WS4 DIFF.

These new differential WiFi oscilloscopes ar eevery day oscilloscopes built by engineers for engineers and can be used via an ethernet connection (LAN, WiFi or WAN) but also still with a USB 2.0 / 3.0 connection. The built-in battery gives the WiFiScope the possibility to perform fully wireless differential measurements. Measurements can then be performed completely galvanically isolated, and over long distances. This wireless PC based data acquisition instrument offers the user more possibilities for measurement applications.

With a WAN connection, world wide differential measurements can be performed. Specific knowledge on networks is not required. The Multi Channel software gives an overview of the available USB instruments and network instruments. Simply tick the instrument and measuring can start.

The differential WiFi oscilloscope has the following advantages:

  • fully wireless differential measurements via WiFi are performed (galvanically isolated) because of the built-in battery
  • mobile differential measurements are possible, e.g. on transport systems and moving installations
  • LAN and WAN data acquisition is available for long distance differential measurements
  • continuous real time high speed data acquisition over both WiFi and LAN/WAN are available
  • USB differential measurements for stand-alone applications and high speed data acquisition up to 200 MSa/s

The WiFiScope is so transparent that it appears that the ethernet connected instrument is connected directly to the computer. All hardware and software functions of the oscilloscope, spectrum analyzer, data logger and voltmeter remain available via the network. Specific network knowledge is not required.

Again the TiePie engineering motto applies: Plug in and measure!

To reduce PC-based data acquisition installation costs and increase flexibility, WiFi and LAN / WAN measuring instruments are the solution. Differential measurement applications that were previously not possible, for example long-distance measurements, measurements at unsafe or noisy places, measurements at a moving installation or reading instruments at different places are now available. With the new differential WiFi oscilloscopes from TiePie engineering, reliable WiFi and LAN / WAN measurement solutions can now be obtained without compromising measurement quality.

The differential WiFi oscilloscope can now be used where previously it was difficult to place a complete measurement setup. Thanks to the WiFi connections, electrical, physical, mechanical and acoustic signals can now be measured remotely. With the WiFi oscilloscope, high speed real time continuous data acquisition rates of 5 MSamples / 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 20 MSamples / second can be achieved with a resolution of 8-16 bits. Via USB connections, high speed real time continuous data acquisition rates of 200 MSamples / second can be achieved with a resolution of 8-16 bits.

Software

Combined with the free Multi Channel oscilloscope software, the WiFiScope WS4 DIFF and WiFiScope WS6 DIFF turn your PC into an High Resolution differential Oscilloscope, Precision Spectrum analyzer, EMI Pre compliance analyzer, High Performance Multimeter, Very Fast differential Data logger and Comprehensive Protocol Analyzer. The Multi Channel oscilloscope software gives you the opportunity to share your data with everybody and lets you analyze your data without the need of an instrument. The Multi Channel oscilloscope software offers sophisticated data analysis capabilities using many user configurable data processing I/O blocks, showing the analysis results in graphs, tables and/or meter displays. Time consuming complicated instrument setups are no longer required using the unique Quick Setup system: select the measurement task you want to accomplish with just up to 4 mouse clicks from a selection dialog that gives access to over 700 different instrument Quick Setups. Each Quick Setup contains all required instrument settings, as well as example signals and background information on how to connect the instrument.

Combined with the Multi Channel oscilloscope software, the WiFiScope WS6 DIFF and WiFiScope WS4 DIFF turn your PC into an High Resolution differential Oscilloscope, Precision Spectrum analyzer, High Performance Multimeter, Very Fast differential Data logger and Comprehensive Protocol Analyzer.

A full Software Development Kit (SDK) for writing your own PC-based data acquisition software is available, as well as examples in C, C++, C#, Python, Matlab, Node.js and Visual Basic.NET. Own written data acquisition software for the Handyscope HS4 DIFF and Handyscope HS6 DIFF can be used directly for the WiFiScope WS4 DIFF and WiFiScope WS6 DIFF. 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.

Elektor Article: USB-SPDIF Interface

Posted on by mixos

The circuit described here is a SPDIF output with a USB interface. It allows connecting Personal Computers, Tablets or Smartphones to Audio equipment including AV receivers, high-end stereo amplifiers or stand-alone audio DACs. It has a infrared remote control receiver that allows controlling media playback and audio volume.

The SPDIF bitstream is generated in software on the same microcontroller that also provides USB connectivity. The SPDIF output is thus a single chip solution that can be implemented with very low hardware effort but is – compared to special USB audio ICs – still flexible and “hackable”. It is even possible to build it on a small breadboard (see below figure).

The PIC32MX270 microcontroller has been chosen for this project. It has the peripherals needed for USB audio applications enough RAM to store encoded SPDIF frames. In addition, there are low pin count variants of these chips that allow for simple PCBs.

The source code can be obtained from https://github.com/kiffie/usb-spdif and used under the terms of the GPL.

DIY voltage and current reference

Posted on by mixos

Petteri Aimonen designed and built his own voltage and current reference:

When developing a data acquisition system, I ran into a need of having fairly accurate current reference to compare against, 0.1% accuracy or better. This is not a particularly high standard, but unable to find a suitable device in my price range, I chose to design my own.

The gold standard when it comes to calibration references is tying them to some reproducible physical behavior. For current references, that would be a Kibble balance and could achieve accuracy on the level of 0.1 ppm (i.e. 0.00001%). Obviously that is not cheap or easy to build.

CN2 6 Pin header connector provided to power up the board and micro-controller interface, CN3 for Full-Duplex communication. CN1 is for AUX power 5V DC.

Any cables I/O can be subjected to electrical noise transients that can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. This module can significantly increase protection and reduce the risk of damage to an expensive control circuit. The device can be used for applications like security systems, chemical production, factory automation, motor control circuit, networked security stations, HVAC and building automation networks.

When the driver enable pin, DE, is logic high, the differential outputs Y and Z follow the logic states at data input D. A logic high at D causes Y to turn high and Z to turn low. In this case, the differential output voltage defined as VOD = V(Y) – V (Z) is positive. When D is low, the output states reverse, Z turns high, Y becomes low, and VOD is negative. When DE is low, both outputs turn high-impedance. In this condition the logic state at D is irrelevant. The DE pin has an internal pull-down resistor to ground, thus when left open the driver is disabled (high impedance) by default. The D pin has an internal pull up resistor to VCC, thus, when left open while the driver is enabled, output Y turns high and Z turns low.

When the receiver enable pin, RE, is logic low, the receiver is enabled. When the differential input voltage defined as VID = V(A) – V(B) is positive and higher than the positive input threshold, VIT+, the receiver output, R, turns high. When VID is negative and less than the negative and lower than the negative input threshold, VIT– , the receiver output, R, turns low. If VID is between VIT+ and VIT– the output is indeterminate. When RE is logic high or left open, the receiver output is high-impedance and the magnitude and polarity of VID are irrelevant. Internal biasing of the receiver inputs causes the output to go failsafe-high when the transceiver is disconnected from the bus (open-circuit), the bus lines are shorted (short-circuit), or the bus is not actively driven (idle bus).
