Product Description

The Instek GOS-620 is a 20 MHz, two-channel analog oscilloscope with ALT triggering, 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. 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 a 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, such as a frequency counter (sold separately). Sweep speed can be magnified by 10 to increase the number of sweeps shown on the display. Additional specifications include a rise time of 17.5 ns (50 ns at 5X magnification) 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. It has European Conformity (CE) marking. It comes with two 20 MHz passive voltage probes; a power cord for 115/230VAC, 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.

GW Instek manufactures test and measurement equipment such as oscilloscopes, spectrum analyzers, signal testers, and video surveillance systems. The company, founded in 1975 and headquartered in Taipei, Taiwan, meets International Organization for Standardization (ISO) standards 9002 and 14001.

Coming from a background of using old tube type scopes that probably needed misc parts replaced and were drifty and unable to lock on easily this thing is amazing. I can lock the signal and zoom in easy as pie. It's amazing. Big step up from my 40 year old heathkit!

I am very pleased with this product. It does all that I need plus more.

I think it is the best product for the price. I did compare prices of

a few other ones.

I don't have a lot of experience with oscilloscopes. Only did a little work in automobile tech school with one.

I use this one for building small receivers and transmitters and will do some troubleshooting on other ones.

I have had the benefit of working with this oscilloscope(but I do not own it). Although my experience has been mostly positive I have to say that the overall design(appearance) of this O-scope makes it seem like it was made 25 years ago even if almost brand new. Green monochrome screens and old style controls just seem antiquated in the 21st century, plus it seems 10 pounds heavier(and 2 times larger) than it should be. But, that is generally true for all analog O-scopes today.

The display/graticule is very basic, measurements are made using the on screen 8x10 "block" style graph with rulers showing smaller sub-divisions(numerical settings are selected with knobs turned to a specific number indicating time or voltage). Those using a display like this for the 1st time and normally accustomed to colorful menus and graphics will probably feel like they stepped back in time.

The price on Amazon for it is reasonable, although the cheapest digital O-scopes are about $50 cheaper. I would never pay more than $400 for an O-scope like this.
