Key Overview

The keys labeled FREQUENCY Channel, System, and Marker are all examples of front-panel keys. The front-panel keys are dark gray, light gray, green, or white in color. Front-panel keys that are white perform an immediate action rather than bringing up a menu. The only green key is the Preset key, which performs an analyzer reset (A summary of all front panel keys and their related menu keys can be found in user’s guide for your analyzer). Pressing most of the dark or light gray front-panel keys accesses menus of functions that are displayed along the right side of the display. These are called menu keys.

Menu keys list functions other than those accessed directly by the front panel keys. To activate a menu key function, press the key immediately to the right of the annotation on the screen. The menu keys that are displayed depend on which front-panel key is pressed and which menu level is enabled.

If a menu key function’s value can be changed, it is called an active function. The function label of the active function is highlighted after that key has been selected. For example, press AMPLITUDE Y Scale. This calls up the menu of related amplitude functions. Note the function labeled Ref Level (the default selected key in the Amplitude menu) is highlighted. Ref Level also appears in the active function block, indicating that it is the active amplitude function and can now be changed using any of the data entry controls.

A menu key with On and Off in its label can be used to turn the menu key’s function on or off. To turn the function on, press the menu key so that On is underlined. To turn the function off, press the menu key so that Off is underlined. In the manual, when On should be underlined, it will be indicated as Function (On).

A function with Auto and Man in the label can either be auto-coupled or have its value manually changed. The value of the function can be changed manually using the numeric keypad, knob, or step keys. To auto-couple a function, press the menu key so that Auto is underlined.

In some key menus, one key label will always be highlighted to show which key has been selected. For example, when you press Marker, you will access a menu of keys in which some of the keys are grouped together by a blue bar on the left side of the menu. The Normal key, which is the Marker menu default key, will be highlighted. When you press another key within the blue bar region, such as Delta, the highlight will move to that key to show it has been selected.
