Advanced User's Guidebook

Up till now, you have already been familiar with the initial operations of

“VERTICAL CONTROLS”, “HORIZONTAL CONTROLS”

and

“TRIGGER

CONTROLS”

, and the functions of the function areas, buttons and knobs in the front

panel of the PDS series oscilloscope. Based the introduction of the previous Chapter,
the user should have an intimate knowledge of the determination of the change of the
oscilloscope setting through observing the status bar. If you have not been familiar
with the above-mentioned operations and methods yet, we advise you to read the
section of “Chapter One Junior Users' Guidebook”.

This chapter will deal with the following topics mainly:

z

How to Set the Vertical System

z

How to Set the Horizontal System

z

How to Set the Trigger System

z

How to Carry on the Sampling Setup

z

How to Set the Display System

z

How to Implement the Storage and Call-out Operations

z

How to Carry on the Auxiliary Function Setting

z

How to Carry on the Automatic Measurement

z

How to Carry on the Cursor Measurement

z

How to Use Executive Buttons

It is recommended that you read this chapter carefully to get acquainted the various
measurement functions and other operation methods of the PDS series oscilloscope.
