EZ OS-5020G oscilloscope

Depending on the type and manufacturer, there are different parameter controls. We thought it would be helpful to delineate specifically the one available at ITP, the EZ OS-5020G.

This oscilloscope is analogue. Its control interface is divided into four main parts as we already viewed at oscilloscope descriptions: Horizontal, Vertical, Trigger, and Generator.

The first three are of interest to us and to anyone who needs to measure a signal. The forth, Generator, is built-in form generator with its own output.

Horizontal axis:

1) Time/Div - controls the amount of information in terms of time per each division. The oscilloscopeÕs display is divided into a grid, where the horizontal axis is time and the vertical is voltage, but in units called IRE (I. Radio Engineers).
The range of times per division goes from seconds, to milliseconds, to microseconds. Adjusting this control it will make the wave stretch in/outÓ horizontally into the displayed and enable a more detailed look at sectors of it.

2) Variable - this will magnify the displayed image, zooming

3) Position - this will slide the whole wave as is to the left or
to the right.

Vertical axis:

1) Volts/Div - this allows how much information in terms of volts is
being displayed. The range is from 5V to 5mV.

2) Position - this adjusts the position on the whole wave up or down
on the display.

3) Mode - enables switching between various channels and display
modes. Ch1, Ch2, Dual (displays both channels), Add (adds both
waves together and displays as one.)


1) Hold/Level - the trigger stabilizes a repetitive waveform, creating a clear picture of the signal.
