Oscilloscope
built 658 days ago
Oscilloscope is a Macintosh program for visualization and analysis of waveforms generated by neurons or by computer simulations of neurons. The current version (version 4) is a carbon application that works in OS X. Oscilloscope can analyze waveforms generated in a variety of ways and by a host of other programs, because it can read and write data stored in two simple and widely-used file formats. One of these is the tab-delimited text file format used by spreadsheets and many graphics programs. The other is a binary format, the HDF scientific data format described and supported by the National Center for Supercomputing Applications (NCSA) and used by a large number of commercial and freeware programs. The waveforms are seen as if on the screen of a digital oscilloscope. As many as 10 files may be open at any time, and the traces from each are shown in a window representing the file.

Oscilloscope measurements are to the time domain what spectrum analysis measurements are to the frequency domain. Most microwave oscilloscope measurements require you to use some type of envelop detector circuit, since microwave frequencies are high compared to the bandwidth of typical oscilloscopes. However, modern digitizing scopes can record and display waveforms as high as millimeterwave frequencies. This is a very recent development, if you asked the Unknown Editor twenty years ago if he would ever be able to go into the lab and display an X-band sine wave on an o-scope, he'd have asked you what you were smoking!

This AVR Oscilloscope clock is available as a kit, using all through-hole components. The kit included ALL components necessary to assemble the board shown below, including a preprogrammed ATmega168 microcontroller. It does not include an oscilloscope and requires an external +5V power source. It ... includes connectors for the Power and RS-232 headers on the board. The user can use these connectors to build the power cable and optional serial communication cable.

Just like an ordinary bench top Oscilloscope, these PC Based Oscilloscopes can read frequencies, voltages, currents and more. Best of all these readings can be viewed on your computer screen. These readings can be stored in your computers memory for later viewing or comparisons. Best of all these PC Oscilloscopes are extremely portable, and weigh no more than a few pounds, making them a great tool for any Electronic Technician who works outside of a traditional repair shop. Most of these PC Based Oscilloscopes operate from Windows based software that is usually supplied with the Oscilloscope. A connection is made through the computers parallel port with an input impedance of around 1M ohm.
