FUNCTIONS OF THE INSTRUMENT
This chapter allows more experienced oscilloscope users to learn more about the
advanced features of this instrument and how to use them. For a complete
description of each function, refer to the next chapter in this manual: "Function
Reference".
This chapter explains the basics of each function and gives examples are given
in a step by step sequence.
Less experienced oscilloscope users should read Chapter 3 before beginning this
chapter.
4.1 INTRODUCTION
All of the oscilloscope models in the PM337xB, PM338xB and PM339xB family
combine the features and operation of an analog oscilloscope with that of a full-
featured Digital Storage Oscilloscope (DSO). Switching between one mode of
operation to the other is done by pressing one (yellow) push button.
Most signal acquisition functions are identical for both modes of operation, even
though the digital mode allows for pretrigger acquisition and display, plus more
powerful logic triggering.
Delayed sweep operation is available in both operating modes.
Cursors operate in both modes.
The digital mode provides access to many powerful calculated measurement and
signal analysis functions.
It also has a completely new feature called AUTO RANGE.
AUTO RANGE automatically adjusts the attenuator or the timebase setting when
the amplitude or the frequency of the signal has changed.
This family of oscilloscopes is available with a 60 MHz, 100 MHz or 200 MHz
bandwidth. There are full four-channel instruments as well as 2+2 channel
models.
The economy version have 2 full channels and an external trigger channel.
PM3394B 200 MHz Full Four Channel Oscilloscope.
The PM3394B offers a 200 MHz bandwidth. Four channels provide equal
bandwidth, and sensitivity ranges. Each channel has full AC/DC/GND coupling
capabilities.
In VERTMENU each channel is set to 50 or 1 M input impedance.
