The Instek GDS-1000-U series is a two-channel, portable digital oscilloscope with a maximum real-time sample rate of 250MS/s, a record length of 4 kpts, auto-set function, advanced triggering, two basic math functions and FFT, 19 measurement parameters, an internal memory for data storage, data logging, and USB connectivity for electronics applications such as such as product design, assembly lines, repair and servicing, and electrical engineering, among others. The sample rate and record length enable long capture times for displaying detailed waveforms. An auto-set function automatically configures the optimum settings for displaying waveforms by selecting the horizontal and vertical scales, positioning the waveform horizontally and vertically, and selecting and activating the trigger source channel. In addition to an edge trigger, the unit has pulse width and video triggers for isolating a specific signal. Two basic math functions—add and subtract—plus FFT (fast fourier transform) and 19 measurement parameters such as average, frequency, and peak-to-peak allow an in-depth analysis of waveforms. A go/no go test function promptly indicates when a signal falls outside user-defined settings, and a zoom function magnifies details of waveforms. Up to 15 waveforms or 15 setups can be stored in the internal memory of the oscilloscope. A data logging function tracks data at user-defined timed intervals for up to 100 hours, logging the data on a USB flash drive (sold separately). Additional specifications include a rise time of 7ns for the 50MHz model, 5ns for the 70MHz model, and 3.5ns for the 100MHz model, and various triggering features. The oscilloscope has a 5.7" color TFT (thin film transistor) LCD with a resolution of 320 x 234 pixels and can show simultaneously show up to two live and two stored waveforms.
The oscilloscope has a USB host port for connecting a flash drive (sold separately) to store data and a USB device port for connecting to a PC for storing data and remote operation. The unit meets EN (European Standard) 61010-031 safety standard, and is rated for CAT (category) II installations to 300V, which covers energy-consuming equipment connected to a fixed installation, including household, office, and laboratory appliances. It has CE (European Conformity) marking. It comes with two passive voltage probes, a power cord for 100 to 240VAC, 50/60Hz, and a user manual.

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.
