OPERATION
3-6
Introduction
This chapter explains how to:
•
Set up the signal generator to produce a typical basic signal.
•
Select the main operating parameters; carrier frequency, output level and type of modulation.
•
Use the full range of supporting facilities.
Note...
When connecting the PULSE INPUT connector to external equipment, a double screened coaxial
cable is used in order for the instrument to conform to EMC requirements.
Conventions
The following conventions are used in this chapter:
RF OUTPUT
Capitals refer to titles marked on the panel.
[MEM]
Text in square brackets indicate hard key titles.
Int. F4
Italics refer to data or messages on the display.
[Pulse]
Italics in square brackets indicate soft key titles, e.g.
[Pulse]
means the soft key
adjacent to the
Pulse
title box at the side of the menu.
Front panel
Parameters are selected by means of hard keys, which have their function printed on them, soft
keys, which do not have any notation, a numerical key pad and a rotary control knob, see Fig. 3-1.
The hard keys have functions which do not change, whereas the soft key functions are determined
by the menu which is being displayed. The numerical keys are used to set parameters to specific
values which can also be varied in steps of any size by using the

keys or the rotary control
knob.
