Chapte II Brief Instroduction

of the UTD1025CL Portable

Digital Storage Oscilloscope

Brief Instroduction of the UTD1025CL

Portable Digital Storage Oscilloscope

The UTD1025CL series of digital storage

oscilloscope referred hereinafter as

oscilloscope are a perfect combination of

usability, uniquie technical index and multipurpose,

helping users completing test more quickly.

The manual concludes the following types:

The UTD1025CL series of digital storage

oscilloscope provides a simple and functionally

clear front panel, enabling to conduct all basic

operations meeting the use habit of traditional

instrument and enabling the user to operate it

proficiently without taking much time to learn and

be familiar with operation of the digital storage

oscilloscope. In order to speed up the adjustment

for measuring, the user can press directly the

button AUTO , and then the instrument shall show

the proper waveform and the gear setting

Apart from the usability, UTD1025CL series of

digital storage oscilloscope possess high

efficiency index and powerful functions required

for quick measuring. To simplify the menu

operation, the combination operation of key

SHIFT on the apparatus and other keys can

enable direct operation of more functions

Besides, the powerful trigger and analysis ability

shall make it easier to capture and analyze the

waveform.The clear liquid crystal display and
