LOCAL OPERATION
4-4
Introduction
All operations of the signal generator are carried out from the front-panel keyboard which is
color-coded. An extensive suite of utility menus make this a very versatile instrument. The
built-in GPIB and RS-232 interfaces enable the instrument to be remotely operated.
Front-panel controls and connectors
Parameters are selected by means of keys which have their functions printed on them, a numerical
key pad and a rotary control knob. The numerical keys are used to set parameters to specific
values which can also be varied in steps of any size by using the [⇑÷10] and [⇓×10] keys or the
rotary control knob.
Connectors
The front-panel connectors are shown in Fig. 4-1 below:
