The Owon Series HDS-N is a handheld electrical test device that combines a two-channel, handheld digital oscilloscope for viewing electrical signals with a manual- and auto-ranging digital multimeter for measuring AC and DC voltage to 400V, AC and DC current to 10 amp, resistance to 40 M?, and capacitance to 100 ?F. The oscilloscope has a maximum real-time sample rate of 100 MS/s for the 20 MHz model, 250 MS/s for the 60 MHz model, and 500 MS/s for the 100 MHz model, and a record length of 6,000 points per channel for acquiring detailed waveforms. Its four math functions—add, subtract, multiply, and divide—plus FFT (fast Fourier transform) and 20 automatic measurements such as period, frequency, and peak-to-peak enable an in-depth analysis of waveforms. Up to four waveforms can be stored in the internal memory. The multimeter has two ranging modes: manual, which allows the user to select the operating range, and auto, which automatically selects the appropriate operating range. The delta relative function allows a measurement to be set as a reference value and displays subsequent measurements as a positive or negative deviation from that value, and the data-hold function freezes a reading on the display to aid documentation. A continuity buzzer confirms that the circuit conducts electricity, and a diode check detects whether a circuit's diodes are working properly. Additional specifications include a rise time of 17.5 ns for the 20 MHz model, 5.8 ns for the 60 MHz model, and 3.5 ns for the 100 MHz model, and various triggering features. The unit has a 3.7" color TFT (thin film transistor) LCD with a resolution of 640 x 480 pixels for viewing waveforms and measurements. An oscilloscope is used for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education, among others. A multimeter is an electrical testing tool for measuring multiple properties of an electrical circuit to verify proper operation or diagnose problems.

The unit has a USB host port and connection cable for storing data on a flash drive (sold separately), a USB device port and an RS-232 port for connecting to a PC, and includes Microsoft Windows compatible software for transmitting data and remote operation. It meets EN (European Standard) 61010-1:2001 safety standard, and is rated for CAT II installations to 400V, which covers energy-consuming equipment connected to a fixed installation, including household, office, and laboratory. It has European Conformity (CE) marking. It comes with two oscilloscope voltage probes; a set of test leads; an extension module for small capacitance measurement; an output terminal for testing of 1 kHz/5V square-wave signal; probe adjustment tools; a USB mass storage connection cable; a USB/RS-232 interface cable; CD-ROM PC software; a rechargeable lithium ion battery; a battery charger/AC adapter for 100 to 240V, 50/60 Hz; and instructions.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

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.
