9400
ground by a wide copper strap — wire is ineffective at RF frequencies because of
the wire’s self-inductance.
9400 Front Panel
Screen Display
labels the four soft buttons and provides control-setting infor-
mation.
Screen
Contrast
button adjusts the optimum viewing angle of the screen dis-
play.
Four
Soft buttons
provide access to all 9400 functions and controls. The func-
tions of the soft buttons change with each screen, according to the labels at the
bottom of each screen.
Next
and
Prev
(
and
) buttons scroll the screen horizontally to accommo-
date menus that cannot fit in the available space. They also allow you to move
from one character to the next when you enter data into your 9400.
These flash when such a menu is in use. Otherwise, they are inactive.
Control Knob
is used to change the setting that is selected by the soft buttons.
To change a value, you ordinarily have to hold down a soft button while you are
turning the control knob.
Recall
button allows you recall a Factory or User Preset.
Selecting the Recall button does not immediately recall a preset. See step
15 on page 2-22 for instructions on recalling a preset.
Modify
button brings you to list of controls that you can use to edit a Factory or
User Preset. If you edit a Factory Preset, you must save it as a new User Preset to
retain your edit.
Setup
button accesses the technical parameters necessary to match the 9400 to
your transmission system.
Escape
button provides an escape from current screen and returns user to the
next higher-level screen. Repeatedly pressing
Escape
will always return you to
the Idle screen, which is at the top level of the screen hierarchy.
Input
meters show the peak input level applied to the 9400’s analog or digital
inputs with reference to 0 = digital full-scale. If the input meter’s red segment
lights up, you are overdriving the 9400’s analog to digital converter, which is a
very common cause of audible distortion.
AGC
meter shows the gain reduction of the slow two-band AGC processing that
precedes the separate analog and digital processing chains. Full-scale is 25 dB
