UTD2000 Series User Manual

Chapter I Introductions

UTD2000 series DSO is desk type DSO. It is designed with conventional user

interface design for any of the basic DSO at the test and measurement industry.

This chapter will cover the following as the beginning guide the UTD2000 series

DSO:

△General inspection

△Functional inspection

△Probe compensation

△Automatic settings of waveform display

△Introduction to the vertical system

△Introduction to the horizontal system

△Introduction to the trigger system

When beginning to use your UTD2000L oscilloscope, first familiarize yourself with the

operation front panel. This chapter briefly describes the operation and functions of the

front panel, so you can get started with your UTD2000L series digital storage oscilloscope

as quickly as possible.

Your UTD2000L oscilloscope comes with a front panel with at-a-glance functions for

easy operation. There are knobs and function keys on the front panel. The functions of

knobs are similar to other Oscilloscope. On the right you will find the screen copy key

(PrtSc) which enables you to save the current screen in an external USB device in picture

format and 5 menu operation keys (designated as F1 to F5 from top down). With these

keys you can set up different options of the current menu. The other keys are function

keys. You can use them to enter different function menus or access particular functions

directly
