A fully integrated Test bench based on Virtual Instruments – mixed signal oscilloscope, logic analyzer, spectrum analyzer and waveform generator using BitScope connected via USB or Ethernet to the now very popular Raspberry Pi.
Raspberry Pi BitScope
Regardless of which BitScope you choose, the new BitScope Library is also available making it easy to create your own embedded test, measurement or data acquisition applications using BitScope and Raspberry Pi. Program in C/C++, Python or Pascal using an easy to use programming API.
BitScope Model 10 – World’s Smallest Mixed Signal PC Based USB Oscilloscope!
BitScope Pocket Analyzer. It’s a problem solver that fits in the palm of your hand. Perfect for designing, prototyping and debugging!
It has 100 MHz bandwidth, up to 40 MSps logic, simultaneous waveform and clock generation and offers serial control of connected devices. It’s the ideal tool for prototyping analog electronics projects, digital and logic circuits or Arduino, Raspberry Pi and other microcontroller based systems with busses, sensors, servos and I/O.

The µSCOPE – A poormans OscilloScope
“These days this obviously can be done much simpler. The present generation of micro controllers is so powerful that such a videoscope concept can be realized almost completely in software. Recently I obtained a sample of the 12f675. On examination of the datasheet of this small 8 pins micro controller from Microchip, it appeared that the small package contained all the components of a miniature videoscope. In short the µSCOPE project was born, with as main objective the challenge of implementing such a relatively complex task in this small micro controller. The result summarized on this web page is a fully functional (memory)scope that samples the analogue input signal and subsequently displays it on a normal TV”
This is a Article by Conrad Hoffman in “Electronics Now, April 1996”.He has an intriguing collection of electronics and Mechanical DIY Tips and Ideas in his site.
The Mini Metrology Lab – Conrad Hoffman
His “Electronic Mess” section has many pages on repairing and restoring old instruments and equipment.
An Excerpt from his pages is a Reading Pleasure due to his rich experience and enticing language.
Troubleshooting Audio Electronics
I ain’t gonna lie. You won’t be a master troubleshooter after reading a couple pages here. Hopefully, what I can do is give you the ability to form a logical plan of attack.
Troubleshooting is done mostly with the mind, not with the soldering iron. We all have problems that get the better of us, at least for a while, but approaching the situation as an interesting puzzle, rather than an unpleasant task to be suffered through, will make the work go quickly.
Success will come from a 3-prong approach, a combination of understanding the circuit, having the means to test it and being in the right frame of mind to correctly interpret the test data. Never underestimate that third component.
He also has a Design and Testing Services called Deep Run Design.
“Bluetooth Multimeter is an intelligent peripheral of android phones, specially designed for engineers. Not only can it easily collect data such as voltage, current and resistance etc., this multimeter can also communicate with phones via bluetooth. Thus, the data gathered will be displayed on your phones.”
Bluetooth Multimeter – Seeed Studio
Totally open source, including hardware, software & Android API. Learn how to create a Platform to connect smartphones with the real life.
The Bluetooth Multimeter is based on Atmega328 – Arduino Pro. It measures the voltage and resistance and current input from the headphone jack, and then sent these data via the Bluetooth frame.
This Bluetooth Multimeter is a portable multimeter, a device that gathers the voltage, resistance and current. and then sent these data to other device via Bluetooth, so, we could display the data through other devices, such as Android, PC and so on.
BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes. This means they capture and display one, two or four analog signals and eight logic or timing signals, simultaneously. Any BitScope can be used as a Digital Storage Oscilloscope, Logic State Analyzer, Spectrum Analyzer or Data Recorder.
Bitscope – PC Oscilloscopes And Analyzers
BS325 is a classic 2+8 channel BitScope which combines deep capture high performance mixed signal data acquisition and full network connectivity in one compact unit.
BitScope 325 – PC Oscilloscope
BS325 connects via ethernet and is electrically isolated from the host. USB adapters are also available.
BS325 is user programmable, software extendable and can be integrated with third party software.
To make this easy the BitScope Library is available for BS325. The library can be used to create custom applications or to integrate one or more BS325 units into specialised testing and data acquisition systems.
The library is included as standard with BS325 and is compatible for Windows, Linux and Macintosh platforms.
VirtualBreadboard(VBB) is for designing and testing embedded software in high-level interactive circuit simulations and rapidly prototyping hardware from those designs.
Virtual Breadboard – Test Embedded Systems
Compared to other simulators many people find the high level approach taken VBB easier to use and much faster to model and test out new ideas and circuit variations.
VBB electronic circuit components are modeled at the function block level and are wired together to create a real-time interactive circuit simulation representing the whole embedded application.
VBB does not use SPICE. SPICE is better suited to subcircuit designs whereas VBB is concerned with merging multiple subcircuits treating each subcircuit as a self contained function block.
“The library makes it possible to show on the beams of the oscilloscope over a million quantization steps of signal per second (on the Pentium III machine) – less than one micro-second is sufficient for one signal sample. This software can be used for linking to real-time controlling programs as longer delays in relay of data to the oscilloscope don’t occur.”
Universal Real-Time Software Oscilloscope GUI DLL Library
“The library is supplied with a comprehensive description of the program interface and simple examples of its use executed in various different program development environments: MS Visual C++® & Visual Basic®; Borland Delphi® & C++Builder®; MathWorks Matlab® & Simulink®, C# (C Sharp).”
“Applied software emitting data to this oscilloscope obtained data via such communications as serial port (RS232, 422, 485), SSI, USB, CAN bus, Ethernet, GRIB (instrumental interface), via custom-made communications equipment and also by collecting information via a data acquisition card with analog-to-digital converters mounted on the PCI bus-bar of a PC.”
delabs Notes –
I am amazed, i did not notice this. I tried it it, not fully, it seems to be quite versatile. I feel this may be useful for hobbists to try out some experiments in oscilloscope and logic analyzer. It would be good if it was Open Source, it may help developing more instruments.
I am not sure about this Library in terms to actual high speed testing or if it may be developed further. But is it interesting.
For students i feel Bitscope offers some nice tools too. BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes.
