Chapter 3 Front-Panel Menu Operation

A front-panel menu tutorial

Menu Example 1 The following steps show you how to turn on the menu, move up and down between levels, move across the choices on each level, and turn off the menu. In this example, you will restore the function generator to the power-on default state. This procedure is recommended before performing the verification procedures in chapter 4.

Menu On/Off

1Turn on the menu.

You enter the menu on the “MENUS” level. The MOD MENU is your first choice on this level.

2 Move across to the SYS MENU choice on this level. 1

>

There are six menu group choices available on the “MENUS” level. Each choice has a letter prefix for easy identification (A: , B: , etc.).

D: SYS MENU

3Move down to the “COMMANDS” level within the SYS MENU. The OUT TERM command is your first choice on this level.

1: OUT TERM

4Move across to the POWER ON command on this level. 1

There are six command choices available in the SYS MENU. Each choice on this level has a number prefix for easy identification (1: , 2: , etc.).

2: POWER ON

1You can also use the knob to scroll left or right through the choices on each level of the menu.
