General Safety Considerations
WARNING
Before this instrument is switched on
,make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor
,inside or
outside the instrument, or disconnection of the protective earth terminal
can result in personal injury
.
WAR
NING
There are many points in the instrument which can, if contacted, cause
personal injury. Be extremely careful.
Any adjustments or service procedures that require operation of the
instrument with protective covers removed should be performed only by
trained service personnel.
WARNING
If this instrument is not used as specied, the protection provided by the
equipment could be impaired. This instrument must be used in anormal
condition (in which all means for protection are intact) only
.
CAUTION
Before this instrument is switched on,
make sure its primary power circuitry
has been adapted to the voltage of the ac power source
.
F
ailure to set the ac power input to the correct voltage could cause damage to
the instrument when the ac power cable is plugged in.
CAUTION
Electrostatic discharge (ESD) on or near input connectors can damage circuits
inside the instrument. Repair of damage due to misuse is
not
covered under
warranty
.
Before connecting any cable to the electrical input, momentarily short the
center and outer conductors of the cable together
.Personnel should be
properly grounded, and should touch the frame of the instrument before
touching any connector
.

CAUTION
The input circuits can be damaged by electrostatic discharge (ESD).
Therefore
,avoid applying static discharges to the front-panel input
connectors
.Before connecting any coaxial cable to the connectors
,
momentarily short the center and outer conductors of the cable together
.
A
void touching the front-panel input connectors without rst touching the
frame of the instrument. Be sure the instrument is properly earth-grounded
to prevent buildup of static charge
.
The electrical plug-in module provides two accurate measurement channels
with user selectable bandwidths
.The lower bandwidth mode provides
excellent oscilloscope noise performance for accurate measurement of
small signals
.The high bandwidth mode provides high-delity display and
measurement of very high-speed waveforms
.
The Agilent 83483A or Agilent 54751A electrical plug-in module provides:

User selectable 12.4 or 20 GHz bandwidth
 2.5 GHz bandwidth trigger channel

Menu and Key Conventions
The keys labeled Trigger
,Disk, and Run are all examples of front-panel keys
.
Pressing some front-panel keys accesses menus of functions that are displayed
along the right side of the display screen. These menus are called softkey
menus
.
Softkey menus list functions other than those accessed directly by the
front-panel keys
.T
oactivate afunction on the softkey menu, press the
unlabeled key immediately next to the annotation on the screen. The
unlabeled keys next to the annotation on the display are called softkeys
.
A
dditional functions are listed in blue type above and below some of the
front-panel keys
.These functions are called shifted functions. To activate a
shifted function, press the blue front-panel Shift key and the front-panel key
next to the desired function.
Throughout this manual front-panel keys are indicated by abox around the
key label, for example
,
4
Timebase
5 .Softkeys are indicated by shading on the
key label, for example
,
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
Mask Align
.The softkeys displayed depend on
the front-panel key pressed and which menu is selected. Shifted functions
are indicated by the front-panel
4
Shift
5
key followed by the shaded shifted
function, for example the Local function (above the
4
Stop/Single
5 front-panel
key) will be shown as
4

A softkey with On and O in its label can be used to turn the softkey's
function on or o. T
oturn the function on, press the softkey so On is
highlighted. T
oturn the function o, press the softkey so O is highlighted.
An On or O softkey function will be indicated throughout this manual as:
NNNNNNNNNNNNNN

Asoftkey such as
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
Sweep Triggered Freerun

.In this case you could choose Triggered by pressing the softkey
until Triggered is highlighted, or choose Freerun by pressing the softkey until
Freerun is highlighted. A choices softkey will be indicated throughout this

The Agilent 83483A, 83484A,B and Agilent
54751A, 54752A,B Electrical Plug-In Module
The electrical plug-in module is one of several plug-in modules available for
the Agilent 83480A, 54750A mainframes
.
The purpose of the plug-in module
The purpose of the plug-in module is to provide measurement channels
,
including sampling, for the mainframe
.The plug-in module scales the input
signal, sets the bandwidth of the system, and allows the oset to be adjusted
so the signal can be viewed. The output of the plug-in module is an analog
signal that is applied to the ADCs on the acquisition boards inside the
mainframe
.The plug-in module also provides atrigger signal input to the
time base/trigger board inside the mainframe.
Front panel of the plug-in module
The plug-in module takes up two
,ofthe four
,mainframe slots
.The front
panel of the plug-in module has two channel inputs and an external
trigger input. The front panel also has two
Probe P
ower
connectors for
Agilent 54700-series probes, an
A
ux P
ower connector for general purpose
use
,and a key for each channel that displays the softkey menu. The softkey
menu allows you to access the channel setup features of the plug-in module
for the selected input.
The front-panel
Probe P
ower connectors allow automatic channel scaling
and probe calibration with Agilent 54700 series probes
. The front-panel
Aux
Power connector provides only power to Agilent 54700 series probes for use
as a trigger input. Probe calibration and scaling are not required for a trigger
input.
