Owon PDS5022T Portable Digital Storage Oscilloscope and Digital Multimeter, 2 Channels, 25MHz, 100MS/s Sample Rate

The Owon PDS5022T is a 25 MHz, two-channel portable digital oscilloscope with a maximum real-time sample rate of 100 MS/s, a record length of 5 kpts per channel, edge and video triggering, two basic math functions and FFT, 20 automatic measurements, auto-scale function, and USB connectivity for electronics applications such as circuit testing, electrical engineering education, and hobbyist projects, among others. The oscilloscope has an external channel that can trigger from a third source while acquiring data from channels 1 and 2. Edge and video triggers allow isolation of specific signals and a trigger hold-off function stabilizes triggering on complex waveforms. Add and subtract math functions plus FFT (fast Fourier transform) along with automatic measurements such as period, frequency, and peak-to-peak enable an in-depth analysis of waveforms. An auto-scale function selects the optimal settings for displaying a waveform, and can be disabled for educational exercises. Up to four waveforms can be stored in the internal memory. The unit has a USB port for connecting to a PC and includes Microsoft Windows compatible software for transmitting data and remote operation. Additional specifications include a rise time of 14.0ns and various triggering features. The oscilloscope has an 8" color TFT (thin film transistor) LCD with a resolution of 640 x 480 pixels for viewing waveforms. It has European Conformity (CE) marking. It comes with two passive voltage probes; CD-ROM PC software; a USB interface cable; a power cord for 100 to 240VAC, 50/60Hz, CAT II; and instructions.

Oscilloscopes are electrical testing devices used to verify the functionality of equipment that generates an electrical signal. Oscilloscopes measure the voltage of an electrical signal over time, and display the measurement as a waveform in a visual graph. The waveform shows the sweeps (or refresh) of voltage on a vertical (Y) axis, and the time on a horizontal (X) axis. Details of a waveform demonstrate the signal over time. Most oscilloscopes have two or four channels for inputting a signal. Some digital oscilloscopes offer more than four channels, allowing channels to be dedicated to specific signals and applications. Bandwidth is the maximum frequency of a signal that an oscilloscope can capture. A constant image will display if a signal is shown at a high frequency. Oscilloscopes may be analog, digital, or mixed signal. An analog oscilloscope directly displays an input signal as a continuous waveform, typically in a luminous phosphor on a cathode ray tube (CRT). A digital oscilloscope converts the input signal into a digital format and reassembles the waveform for display, typically on an LCD. A mixed signal oscilloscope (MSO) displays both analog and digital formats. Some oscilloscopes can display more than one channel and type of measurement simultaneously. Some oscilloscopes can capture waveform signals to memory, and recall them. They may provide real-time intensity grading, and may have the ability to adjust frequency of display. Oscilloscopes can be powered with batteries or electricity, or may have a built-in generator. They are commonly used for testing, measuring, and inspecting in science, engineering, telecommunications, automotive, and electronics applications.
