SAFETY REQUIREMENTS
This section contains information and warnings that must be observed to keep the
instrument operating in a correct and safe condition. You are required to follow
generally accepted safety procedures in addition to the safety precautions specified in
this section.
Safety Symbols and Terms
Where the following symbols or terms appear on the instrument’s front or rear panels,
or in this manual, they alert you to important safety considerations.
CAUTION
WARNING
A A
Getting Started Manual
WJ-A-GS-E Rev A 9
CAT I
Operating Environment
The instrument is intended for indoor use
and should be operated in a clean, dry
environment.
Note: Direct sunlight, radiators, and other
heat sources should be taken into account
when assessing the ambient temperature.
WARNING
The scope must not be operated in
explosive, dusty, or wet/damp
atmospheres.
The design of the instrument has been
verified to conform to EN 61010-1 safety
standard per the following limits:
Installation (Overvoltage) Categories II
(Mains Supply Connector) & I (Measuring
Terminals)
Pollution Degree 2
Protection Class I
Note:
Installation (Overvoltage) Category II refers
to local distribution level, which is applicable
to equipment connected to the mains supply
(AC power source).
Installation (Overvoltage) Category I refers
to signal level, which is applicable to
equipment measuring terminals that are
connected to source circuits in which
measures are taken to limit transient
voltages to an appropriately low level.
Pollution Degree 2 refers to an operating
environment where normally only dry non-
conductive pollution occurs. Occasionally a
CAUTION
Protect the scope’s display touch
screen from excessive impacts with
foreign objects.
CAUTION
Do not exceed the maximum specified
front panel terminal (CH1, CH2, CH3,
CH4, EXT) voltage levels. Refer to
Specifications for more details.
CAUTION
Do not connect or disconnect probes or
test leads while they are connected to a
voltage source.
WaveJet 300A Series
10 WJ-A-GS-E Rev A
temporary conductivity caused by
condensation must be expected.
Protection Class 1 refers to a grounded
equipment, in which protection against
electric shock is achieved by Basic
Insulation and by means of a connection to
the protective ground conductor in the
building wiring.
Cooling Requirements
The instrument relies on forced air cooling
with internal fans and ventilation openings.
Care must be taken to avoid restricting the
airflow around the apertures (fan holes) at
each side of the scope. To ensure adequate
ventilation it is required to leave a10 cm (4
inch) minimum gap around the sides of the
instrument.
CAUTION
Do not block the ventilation holes
located on both sides of the scope.
CAUTION
Do not allow any foreign matter to enter
the scope through the ventilation holes,
etc.
AC Power Source
The instrument operates from a single-
phase, 100 to 240 Vrms (+/-10%) AC power
source at 50/60 Hz (+/-5%), or single-phase
100 to 120 Vrms (+/-10%) AC power source at
400 Hz (+/-5%).
No manual voltage selection is required
because the instrument automatically adapts
to line voltage.
Depending on the accessories installed (PC
port plug-ins, Ethernet & GPIB options, etc.),
the instrument can draw up to 75 W (75 VA).
Note:
The instrument automatically adapts
itself to the AC line input within the
following ranges:
Voltage
Range:
90 to 264 Vrms
90 to 132 Vrms
Frequency
Range:
47 to 63 Hz
380 to 420 Hz
Getting Started Manual
WJ-A-GS-E Rev A 11
Power and Ground Connections
The instrument is provided with a grounded
cord set containing a molded three-terminal
polarized plug and a standard IEC320 (Type
C13) connector for making line voltage and
safety ground connection. The AC inlet
ground terminal is connected directly to the
frame of the instrument. For adequate
protection against electrical shock hazard,
the power cord plug must be inserted into a
mating AC outlet containing a safety ground
contact. Use only the power cord specified
for this instrument and certified for the
country of use.
WARNING
Electrical Shock Hazard!
Any interruption of the protective
conductor inside or outside of the
scope, or disconnection of the safety
ground terminal creates a hazardous
situation.
Intentional interruption is prohibited.
The scope should be positioned to allow
easy access to the socket-outlet. To
completely remove power to the scope,
unplug the instrument’s power cord from the
AC outlet.
It is recommended that the power cord be
unplugged from the AC outlet if the scope is
not to be used for an extended period of
time.
CAUTION
The outer shells of the front panel
terminals (CH1, CH2, CH3, CH4, EXT)
are connected to the instrument’s
chassis and therefore to the safety
ground.
Calibration
The recommended calibration interval is one year. Calibration should be performed by
qualified personnel only.
Cleaning
Clean only the exterior of the instrument,
using a damp, soft cloth. Do not use
chemicals or abrasive elements. Under no
circumstances allow moisture to penetrate
the instrument. To avoid electrical shock,
unplug the power cord from the AC outlet
before cleaning.
WARNING
Electrical Shock Hazard!
No operator serviceable parts inside.
Do not remove covers.
Refer servicing to qualified personnel.
WaveJet 300A Series
12 WJ-A-GS-E Rev A
Abnormal Conditions
Operate the instrument only as intended by
the manufacturer.
If you suspect the scope’s protection has
been impaired, disconnect the power cord
and secure the instrument against any
unintended operation.
The scope’s protection is likely to be
impaired if, for example, the instrument
shows visible damage or has been subjected
to severe transport stresses.
Proper use of the instrument depends on
careful reading of all instructions and labels.
WARNING
Any use of the scope in a manner not
specified by the manufacturer may
impair the instrument’s safety
protection.

PROBES
LeCroy provides a passive probe for each WaveJet oscilloscope channel, as follows:
PP006A
350 and 500 MHz
PP010
100 and 200 MHz
Probe Compensation
Passive probes must be compensated to flatten overshoot. This is accomplished by
means of a trimmer at the connector end of the probe.
1. Attach the connector end of your PP006A or PP010 probe to any channel.
2. Connect the probe end to the CAL output connector at the front of the scope.
3. Adjust the trim pot at the connector end of the probe until the square wave is
as flat as possible.

WAVEFORM MEASUREMENTS
Measuring with Cursors
Cursors are important tools that aid you in measuring signal values. Cursors are
boundary markers that you can move across the grid. Use cursors to make fast,
accurate measurements and to eliminate guesswork.
Cursor Measurement Selections
Time cursors are vertical lines that you move horizontally to
measure the difference in time or frequency values between
the cursors.
Amplitude cursors measure the difference in Y values between
the cursors.
You can display both time and amplitude measurements
together in this mode.

PARAMETER MEASUREMENTS
Waveform analysis typically begins with the measurement of parameters. Parameter
measurement tools determine a wide range of waveform properties. Use them to
automatically calculate many attributes of your waveform, like rise time, rms voltage,
and peak-to-peak voltage, for example.
You can make common measurements on one or more waveforms. Parameter values
are displayed below the grid.
Measure Modes
Standard Vertical Parameters
Maximum -- Measures highest point in waveform. Unlike top, it does not
assume the waveform has two levels.
Minimum -- Measures the lowest point in a waveform. Unlike base, it does not
assume the waveform has two levels.
Peak-Peak -- Difference between highest and lowest points in the waveform.
RMS -- Root Mean Square of data between the cursors -- about the same as
sdev for a zero-mean waveform.
Cycle RMS -- Cyclic root mean square: Computes the square root of the sum of
squares of data values divided by number of points. Contrary to rms,
calculation is performed over an integer number of cycles, eliminating bias
caused by fractional intervals.
Mean -- Average of the data for a time domain waveform. Computed as
centroid of distribution for a histogram.
Cycle Mean -- Computes the average of the waveform data. Contrary to mean,
computes the average over an integer number of cycles, eliminating bias
caused by fractional intervals.
Top -- Higher of two most probable states, the lower being base; it is
characteristic of rectangular waveforms and represents the higher most
probable state determined from the statistical distribution of data point values in
the waveform.
Base -- Lower of two most probable states (higher is top). Measures lower level
in two-level signals. Differs from min in that noise, overshoot, undershoot, and
ringing do not affect measurement.
Getting Started Manual
WJ-A-GS-E Rev A 53
Top-Base -- Measures the difference between upper and lower levels in two-
level signals. Differs from pkpk in that noise, overshoot, undershoot, and ringing
do not affect the measurement.
+Overshoot -- Amount of overshoot following a rising edge specified as
percentage of amplitude.
-Overshoot -- Amount of overshoot following a rising edge specified as
percentage of amplitude.
Standard Horizontal Parameters
Rise Time 10-90% -- Detects the first rise to pass through 50% of the amplitude
(top - base) of the waveform within the measurement section, and then
measures the time of transition from 10% to 90% at that rise.
Rise Time 20-80% -- Detects the first rise to pass through 50% of the amplitude
(top - base) of the waveform within the measurement section, and then
measures the time of transition from 20% to 80% at that rise.
Fall Time 80-20% -- Detects the first fall to pass through 50% of the amplitude
(top - base) of the waveform within the measurement section, and then
measures the time of transition from 80% to 20% at that fall.
Fall Time 90-10% -- Detects the first fall to pass through 50% of the amplitude
(top - base) of the waveform within the measurement section, and then
measures the time of transition from 90% to 10% at that fall.
Frequency -- Period of cyclic signal measured as time between every other pair
of 50% crossings. Starting with first transition after left cursor, the period is
measured for each transition pair. Values then averaged and reciprocal used to
give frequency.
Period -- Period of a cyclic signal measured as time between every other pair of
50% crossings. Starting with first transition after left cursor, period is measured
for each transition pair, with values averaged to give final result.
No. of +Pulses -- An integer number of positive pulses.
No. of -Pulses -- An integer number of negative pulses.
+Pulse Width -- Measures the time from the first rise until the first fall to pass
through 50% of the amplitude (top-base) of the waveform within the
measurement section.
-Pulse Width -- Measures the time from the first fall until the first rise to pass
through 50% of the amplitude (top-base) of the waveform within the
measurement section.
Duty Cycle -- Width as percentage of period.
WaveJet 300A Series
54 WJ-A-GS-E Rev A
Other Parameters
Integral -- Computes area of waveform between cursors relative to zero level.
Values greater than zero contribute positively to the area; values less than zero
negatively.
Skew -- Measures from the 50% crossing of the first edge of a channel to the
50% crossing of a second channel.
Skew@Level -- Same as Skew, but with user-defined level.

WAVEFORM MATH
Standard math functions comprise addition, subtraction, multiplication, and FFT. The
“Math” menu is accessed by pressing the MATH front panel button in the VERTICAL
control group.
Source can be any channel, but not another math trace.
Select math operator +, -, x, or FFT.
If FFT is selected, select a window type:
Rectangular -- Normally used when the signal is transient
(completely contained in the time-domain window) or
known to have a fundamental frequency component that is
an integer multiple of the fundamental frequency of the
window.
VonHann -- Reduces leakage and improves amplitude
accuracy. However, frequency resolution is also reduced.
Flat Top -- Provides excellent amplitude accuracy with
moderate reduction of leakage, but with reduced frequency
resolution.

Language selects a UI local language. No reboot is required
to accept a change in language.
Select Date & Time to set the current time and to determine
the clock mode at the bottom of the screen: real time clock
(RTC) or trigger time stamp (TRG).
As you change the gain, Offset Setting allows you to either
keep the vertical offset level indicator stationary (Division) or
to have it move with the actual voltage level (Volts). When
Division is selected, the waveform will remain on the grid as
you increase the gain; whereas, if Volts is selected, the
waveform could move off the grid.
If desired, use Power Management to set the screen saver
timer (up to 15 minutes) and the power off timer (up to 60
minutes). These features can be set to Never also.
You can also set the backlight (screen) intensity (3 levels),
which is different from grid intensity (see menu 2/2).
