The Instek GOS-630FC is a 30MHz, two-channel analog oscilloscope and frequency counter with an timebase auto-range function, ALT triggering, XY mode, Z-axis input, TV synchronization capability, and channel 1 output for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education, among others. A built-in real-time frequency counter measures frequency from 50Hz to 30MHz, displaying readings on a five-digit LCD. The timebase auto-range function automatically selects the optimum sweep time for displaying waveforms. This oscilloscope has a vertical sensitivity to 1mV per division for capturing low-level signals. An ALT triggering function displays the signal from both channels simultaneously, and the XY mode compares the signal amplitude from each channel for determining the phase difference. The Z-axis input modulates the intensity of the waveform, the TV synchronization circuit allows triggering of TV-V and TV-H signals, and the channel 1 output can apply a signal to an external device. Additional specifications include a rise time of 11.7ns (50ns at 1 to 2mV per division) and various triggering features. The oscilloscope has a 6" CRT (cathode ray tube) display with an internal 8 x 10 division grid (each division is 1 cm) for viewing waveforms and an LCD that simultaneously shows readings for frequency, voltage per division, times per division, and XY mode. The LCD has a backlight for visibility in low light. The oscilloscope meets European Standard (EN) 61010-1:2001 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 European Conformity (CE) marking. It comes with two 60MHz passive voltage probes, a power cord for 115/230VAC, 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.
