BitScope BS100U

The BS100U by BitScope is a high performance isolated USB mixed signal oscilloscope desgined for use with a PC or laptop computer. This oscilloscope is perfect for engineers, college students or electronic and robotic enthusiasts! The BS100U is a powerful instrument that will help you design your hardware and software more effeciently. It also helps you quickly diagnose circuit problems. A mixed signal oscilloscope is an excellent tool for college engineering students and hobbyists as it will aid in your learning about circuit design and operation. The BS100U is available by itself or as a package with two 100MHz probes.

BS100 combines a dual channel digital storage oscilloscope, 8 channel logic analyzer and DSP waveform generator with a real-time spectrum analyzer and data recorder in one small unit, fully opto-isolated from the PC to which it is connected! Whew...there is a lot of functionality and uses for this powerful device.

Key features of the BS100U by BitScope:

• 100 MHz. analog Input bandwidth
• Dual converters with 4 inputs (BNC & POD)
• 8 logic/timing channels and Smart POD
• 40MS/s logic analyzer, 25nS capture
• DSP waveform generator (option)
• Real-time spectrum analyzer
• Mixed signal data recorder
• Electrically isolated USB
• User programmable

Unique among USB oscilloscopes, BS100U is opto-isolated which decouples it from your PC. It is powered independently and can be referenced to a ground potential different than the PC's ground. Drop-outs due to ground-loops across the USB connection or USB glitches in difficult test and measurement situations are never a problem. The BS100U gives you the freedom to work in electrically noisy environments such as automotive shops or with high power machinery or in applications where a common ground for both your circuit and the PC may simply be impossible to find.

BS100U has 4 analog inputs feeding 2 capture channels and another 8 concurrent logic channels.

The BS100U includes an adjustable external trigger input, a calibration output and low power and standby operating modes for extended use on battery power. Because its quiescent current is measured in microamps it doesn't even need a power switch, simply plug it in and leave it connected.

The two BNC connectors provide access to the analog channels and DSP waveform generator output (via CH-B). The 26-way Smart POD connector provides access to the other two analog inputs as well as the 8 logic inputs, power, ground, serial I/O and waveform generator signals. BS100U is compatible with industry standard oscilloscope probes. If you already have probes, great - there is no need to buy them. If you don't have probes then you can purchase a kit from us containing a BS100U and 2 x1/x10 switchable 100 MHz. bandwidth analog probes.

Capture LEDs in channel colors (yellow, green and blue) on the front panel provide instant visual feedback and USB, data and power LEDs on the back indicate power and PC connection status. The 12VDC power socket and USB connector are located on the back.

Software

Included with BS100U is BitScope DSO, BitScope's powerful test and measurement software. DSO runs on both Windows and Linux computers. When first powered on it presents a familiar dual channel digital oscilloscope display. However there's much more to it than that.

Virtual Instrument and split screen display buttons down the right side allow you to select from an array of integrated test instruments. These include a mixed signal and digital storage scope, logic analyzer, spectrum analyzer, X-Y phase plotter and an integrated data recorder. Whether you're looking at waveforms down at audio frequencies or analyzing clock edges at the high speed of microcontroller and digital logic circuits, DSO and BS100U meet the challenge.

And of course you can select the mixed signal or logic capture modes to analyze logic state transitions and timing or choose the spectrum analyzer to display waveforms and their spectra together, and all in real-time with display refresh rates as high as 50Hz.

User Programmable

BS100U is user programmable and software extendable making it ideal for use in customised data acquistion and test & measurement applications.

The BitLib Application Programming Library allows you to take advantage of BS100U's powerful mixed mode waveform and logic data capture capabilities using several different programming languages and numerical analysis environments. This free library is available for Windows and Linux platforms and comes with some example applications to get you started.

Because BitLib is DLL based you can use it to integrate BS100U with third-party numerical analysis and data acquisitions systems such as MathWorks' MatLab and National Instruments' LabVIEW. Alternatively you can write your own applications with tools such as Microsoft Visual Studio or Borland Delphi. Open source options are also supported with bindings for many programming languages.
