SAFETY SUMMARY
The following are general safety precautions that are
not related to any specific procedures and therefore may
not appear elsewhere in this publication. These are re-
commended precautions that personnel must understand
and apply during many phases of operation and
maintenance.
KEEY AWAY FROM LIVE CIRCUITS
Electrical-shock hazards are present in this instrument.
Operating personnel must observe safety regulations at all
times and should not remove the protective covers unless
they are qualified maintenance personnel. Do not replace
components or repair the instrument unless it is discon-
nected from the line voltage source and turned off. Under
certain conditions some components may retain dangerous
potentials even when the instrument is unplugged and
turned off. To prevent shocks, discharge and ground
circuits that are being repaired.
DO NOT SERVICE OR ADJUST ALONE
Do not service or make internal adjustments to this
instrument unless another person capable of giving first
aid and resusitation is present.
DO NOT OPERATE IN EXPLOSIVE
ATMOSPHERE
Do not operate this instrument in an area where flam-
mable gases or fumes are present. Such operation could
cause an explosion.
GROUND THE INSTRUMENT
To prevent electrical-shock hazards, insert the power-
cord plug only in proper mating power outlets.
SAFETY WARNING IDENTIFICATION
Personnel safety warnings that appear in the text of
this manual are identified with the following symbol:

1-3. GENERAL INFORMATION
a. Equipment Description. The AN/USM-425(V)1 is a
solid state, dual channel, 100 megahertz bandwidth, de-
layed sweep, general purpose oscilloscope. Each vertical
channel has ten calibrated deflection factors from 5milli-
volts/division to 5volts/division selected in a1-2-5 se-
quence. The horizontal deflection system has calibrated
sweep rates of 0.5 seconds/division to 0.05 microseconds/
division in 22 steps. It also has delayed sweep rates of 50
milliseconds/division to 0.05 microseconds/division in 19
steps. Aten times magnifier expands each horizontal sweep
rate to amaximum of 5nanoseconds/division. An X-Y
display mode is provided through vertical mode and hori-
zontal sweep speed selection. The instrument with its de-
tachable front cover and accessories is shown in Figure 1-0.
(8) Section VIII, Maintenance Parts List. Contains Accessories Supplied. Figure 8-2 illustrates and lists
the illustrated parts breakdown ilTustrations and parts accessories that are shipped with the instrument and
descriptions. stored in its front cover.
