Bitscope – PC Oscilloscopes And Analyzers

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. USB BitScope 310

USB BitScope 310 – PC Oscilloscope

BS310U is a robust general purpose USB Mixed Signal Scope and Data Acquisition device. BS310U is backward compatible with BS300U which it replaces.

It has 4 times as much capture buffer, a software switchable x10 and x50 analog input multiplier and AC/DC coupling, switchable 50 ohm termination, a double speed built-in USB host interface all in a physical package about 2/3 the size and weight of BS300U.

BS325 with third party software

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.

This Insulation Testing Reference by AEMC Instruments is a Must Read for all Instrumentation and Electrical Professionals. Even Students and Enthusiasts who want to learn more about Insulation, can find this informative. The other reference articles also are of Learning Interest. Insulation Testing is a Part of Power, Energy, Green, Solar Systems as well. It is an Important part of Product Safety.

Seen on the right is the Megohmmeter from AEMC. 6505 is a portable battery/mains powered instrument in a rugged field case.

This Features include automatic calculation and presentation of the Dielectric Absorption Ratio (DAR) and Polarization Index (PI). The Model 6505 displays the test voltage, insulation resistance and the leakage current during the test.

To make an analog design using log amps or multipliers, discovercircuits – four-quad is good for learning. Using a uP for math is better. Look at these links below. Build a Power Meter ! The Metrics for Going Green is with a Energy/Power/Watt meter.

The usefulness of an oscilloscope is not limited to the world of electronics. With the proper transducer, an oscilloscope can measure all kinds of phenomena.

Introduction to Oscilloscope – The single most important diagnostic tool used by experimental physicists is the oscilloscope. Certainly all scientists and engineers should be familiar with this common instrument, shown in the Fig. 1. An oscilloscope (scope for short) can be used to “see” an electrical signal by displaying a replica of a voltage signal as a function of time.

Introduction to Oscilloscope
Oscilloscope – Wikipedia

Oscilloscopes are used to observe the change of an electrical signal over time, such that voltage and time describe a shape which is continuously graphed against a calibrated scale. The observed waveform can be analyzed for such properties as amplitude, frequency, rise time, time interval, distortion and others.

Tektronix Reference Materials

There are many older Tektronix instruments that, with a little care and restoration, are just as useful as the latest and greatest. Knowing what you have or need, and how to use it, are often more important than having the “very latest”.

As important as knowing what is going on inside, is knowing how to make effective measurements using an integral part of the oscilloscope: the Scope Probes. The probe and how it is used, can make or break the usefulness of the oscilloscope.

Basic Function of an Oscilloscope

Interactive Demo – The oscilloscope is an electronic instrument widely used in making electrical measurements. The main component of the oscilloscope is the cathode ray tube (CRT). The CRT is a vacuum tube in which electrons are accelerated and deflected under the influence of electric field.

“From a small garage in Palo Alto, California, to employees around the world serving customers in 110 countries, Agilent has a long history of innovation and leadership in the communications, electronics, semiconductor, test and measurement, life sciences and chemical analysis industries.”

The company founded by William “Bill” Redington Hewlett and Dave Packard was know as Hewlett-Packard Company or HP. This was a Test and Measurement company. First popular product was a precision audio oscillator, the Model HP200A.

Later Computer and Printer products divisions retained the brand and firm and Agilent was spun off for for the Test and Measurement and other non-computer product line.
