Protek DSO-2250 PC-Based Digital Storage Oscilloscope, 100MHz, 2-Channel, USB Interface

The Protek DSO-2250 is a 100MHz, two-channel PC-based digital storage oscilloscope with a 250MS/s per channel sample rate and a 512kpts per channel record length for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education, among others. It has a time-base sensitivity of 4ns per division for accurate display of waveforms. It has Edge triggers and its math functions include FFT (fast fourier transform).The oscilloscope is used in conjunction with a computer (sold separately) through a USB interface, and displays waveforms on the computer's monitor. The oscilloscope draws power from the USB interface and does not require an external power source.

Oscilloscopes are electrical testing devices used to verify the functionality of an electrical signal generator. Oscilloscopes measure an electrical signal over time, and display the waveform signals in a visual graph. The waveform shows the sweeps (or refresh) of voltage on a vertical (Y) axis, and can display time on a horizontal (X) axis. Details of a waveshape demonstrate the signal over time. Oscilloscopes can display in a digital or analog view. An analog oscilloscope has continuous waveform display, typically in a luminous phosphor. Some oscilloscopes can display more than one channel and type of measurement simultaneously. Some oscilloscopes can capture waveform signals to memory, and recall them. Oscilloscopes may provide real-time intensity grading. Some oscilloscopes have the ability to adjust frequency of display. A constant image will display if a signal is shown at a high frequency. Oscilloscopes can be powered with batteries or electricity, or may have a built-in generator. They may have Canadian Standards Association (CSA) or European Conformity (CE) certification, or a specific category (CAT) safety rating, such as CAT5e. Oscilloscopes are commonly used for testing, measuring, and inspecting in science, engineering, telecommunications, automotive, and industry applications.

GS Instruments Co., Ltd. (GSI) manufactures test and measuring instruments such as oscilloscopes and function generators under the Protek brand of its subsidiary Heung Chang (Qingdao) Electronics Co., Ltd. The company, founded in 1972, is headquartered in South Korea and has a U.S. office in Overland Park, KS.
