hazardous situation.

Intentional interruption is prohibited.

The oscilloscope should be positioned to allow easy access to the socket­outlet. Disconnect the oscilloscope from the AC supply by unplugging the
instrument’s power cord from the AC outlet after the oscilloscope is placed
in Standby state.

CAUTION

The outer shells of the front panel BNC terminals (CH1, CH2, EXT TRIG)
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.

Avoid electrical shock hazard by unplugging the power cord from the AC
outlet before cleaning.

Choosing Coupling

You can choose one of these input coupling modes:

 DC - Passes both AC and DC components of the input signal.
 AC - Blocks the DC component of the input signal and attenuates

signals below 10 Hz.

 GND - Disconnects the input signal. Use GND coupling to display a

zero-volt waveform. Internally, the channel input is connected to a
zero-volt reference level.

PLEASE NOTE THE FOLLOWING:

 If the channel is set to DC coupling, you can quickly measure the DC

component of the signal by simply noting its distance from the
ground symbol.

 If the channel is set to AC coupling, the DC component of the signal

is blocked allowing you to use greater sensitivity to display the AC
component of the symbol.

1. To choose an input coupling mode, turn on the channel whose
coupling you want to change by pressing the appropriate channel
button (CH1 or CH2).

2. Press the Coupling option button on page 1/2 of the channel menu,
then select a coupling mode from the menu.

To turn the Bandwidth Limit ON, turn on the
channel by pressing the appropriate channel
button (CH1 or CH2).

Press the BW Limit option button on page 1/2
of the channel menu, then select On.

Limiting Bandwidth

You can limit the bandwidth to reduce display noise. When you turn
Bandwidth Limit ON, the Bandwidth Limit value is set to 20 MHz. It also
filters the signal to reduce noise and other unwanted high frequency
components.

Note: The oscilloscope vertical response rolls off slowly above its
bandwidth; or, above 20 MHz when the Bandwidth Limit is set to ON.
Therefore, the FFT spectrum can show valid frequency information higher
than the oscilloscope bandwidth. However, the magnitude information near
or above the bandwidth will not be accurate.

the sensitivity to Coarse (fixed - the default setting), the gain adjustment is
set to 1-2-5 increments from 2 mV/div, 5 mV/div, 10 mV/div to 5 V/div.
When you set the sensitivity to Fine (variable), it changes the resolution to
small steps between the coarse settings.

Note: The vertical scale readout displays the actual Volts/Div setting when
Fine (variable) is selected. Changing the setting to Coarse (fixed) does not
change the vertical scale until the Volts/Div control is adjusted.

Sampling Modes

Acquisition Sampling Modes

When you acquire a signal, the oscilloscope converts it into a digital form
and displays a waveform. The acquisition sampling mode defines how the
signal is digitized and the timebase setting affects the time span and level
of detail in the acquisition. You can change the Sampling modes by
pressing the ACQUIRE front panel button.

There are three basic sampling modes:

 Sampling- samples the signal in evenly-spaced intervals to construct

the waveform.

Note: You can use this mode to reduce random noise. This mode
does not acquire rapid variation in the signal that may occur
between samples. This can result in narrow pulses being missed. In
this case, you can use Peak Detect mode to acquire data.

 Peak Detect - captures the maximum and minimum values that

occur in a signal. It finds the highest and lowest record points over
many acquisitions.

Note: The oscilloscope can acquire and display narrow pulses,
which may otherwise have been missed in Sampling mode. Noise
will appear to be higher in this mode.

 Average - acquires up to 256 waveforms, averages them, and

displays the resulting waveform.

Note: You can use this mode to reduce random noise.

In addition, you can also choose between Equivalent Time Sampling and
Real Time Sampling.

 Equivalent Time Sampling can achieve up to 20 ps of horizontal

resolution (equivalent to 50 GS/s). This mode is good for observing
repetitive waveforms.

 Real Time Sampling can be used for repetitive and non-repetitive

waveforms.

Getting Started Manual

To choose a sampling mode, press the ACQUIRE
front panel button. On the Acquire menu, press the
Acquisition option button and select a sampling
mode. If you select the Average sampling mode,
press the Averages option button and select the
number of waveforms (4, 16, 32, 64, 128, or 256).

Press the Mode option button and select Equ Time
or Real Time sampling.

Press the Sa Rate option button and turn the
Time/div front panel knob to display the sampling
rate at the corresponding timebase scale.

Acquiring Waveforms

You can choose to acquire a single waveform or to acquire waveforms
continuously. If you want to acquire a single waveform, press the SINGLE
front panel button. Each time you press the SINGLE front panel button, the
oscilloscope begins to acquire another waveform. After the oscilloscope
detects a trigger, it completes the acquisition and stops. If you want to
acquire waveforms continuously, press the RUN/STOP front panel button.
Press the button again to stop the acquisition.

When you start an acquisition, the oscilloscope goes through the following
steps:

1. Acquires enough data to fill the portion of the waveform record to the
left of the trigger point (pre-trigger).

2. Continues to acquire data while waiting for the trigger condition to
occur.

3. Detects the trigger condition.

4. Continues to acquire data until the waveform record is full.

5. Displays the waveform.

Changing the Timebase

The oscilloscope digitizes waveforms by acquiring the value of an input
signal at discrete points. The timebase allows you to control how often the
values are digitized. You can change the timebase using the Time/div front
panel knob in the Horizontal Control group. As you turn the Time/div front
panel knob, the value is displayed at the bottom of the screen.

Analyzing Waveforms

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.

There are three cursor measurement modes:

 Manual - displays two horizontal parallel cursors or vertical parallel

cursors to measure voltage or time. Voltage cursors appear as
horizontal lines on the display and measure the vertical parameters.
Time cursors appear as vertical lines on the display and measure the
horizontal parameters. You can move the cursor by turning the
Adjust front panel knob. Before using cursors, you should make
sure that you have set the signal source as the channel for
measuring.

 Track - displays two cross-cursors. The cross-cursors set the

position on the waveform automatically. You can adjust the cursor
position on the waveform by turning the Adjust front panel knob. The
values are displayed on the top of the grid display.

 Auto - Automatically places markers of what is being measured on

the waveform. These markers clarify parameter measurements by
displaying cursors and a visual representation of what is being
measured. When in Auto cursor mode, as you select measurement
parameters the markers will be displayed for the measurements.

CURSOR MEASUREMENT SELECTIONS

 Time cursors are vertical lines that you move horizontally to measure

the difference in time or frequency values between the cursors.

 Voltage cursors appear as horizontal lines on the display and

measure the vertical parameters.

 The measurement values listed on the top of the grid display are as

follows:
A→T - the horizontal position of Cursor A (Time cursor centered
around the midpoint of the screen)
A→V - the vertical position of Cursor A (Voltage cursor centered
around the channel ground level)
B→T - the horizontal position of Cursor B (Time cursor centered
around the midpoint of the screen)
B→V - the vertical position of Cursor B (Voltage cursor centered
around the channel ground level)
▲T - Horizontal space between Cursor A and Cursor B (Time value
between the two cursors)
1/▲T - the reciprocal of the horizontal space between Cursor A and
Cursor B
▲V - the vertical space between Cursor A and Cursor B (Voltage
value between the two cursors)

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 access the parameter measurements by pressing the MEASURE
front panel button and then pressing an option button for Voltage, Time,
Delay or All Measurements for each channel. Parameter values are
displayed on the Measure flyout menu.

WA-GSM-E-RevA

 Vpp - Difference between highest and lowest

points in the waveform.

 Vmax - Measures highest point in waveform.

Unlike top, it does not assume the waveform has two
levels.

 Vmin - Measures the lowest point in a

waveform. Unlike base, it does not assume the
waveform has two levels.

 Mean - Average of the data for a time domain

waveform. Computed as centroid of distribution for a
histogram.

 Vrms - Root Mean Square of data between

the cursors -- about the same as sdev for a zero-mean
waveform.

 Crms - 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.

 Vtop - 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.

 Vbase - 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.

 Vavg - Arithmetic mean over the first cycle in

the waveform.

 Vamp - Voltage between Vtop and Vbase of a

waveform.

 ROVShoot - (Vmax-Vtop)/Vamp after the

waveform rising transition.

 FOVShoot - (Vmin-Vbase)/Vamp after the

waveform falling transition.

 RPREShoot - (Vmin-Vbase)/Vamp before the

waveform rising transition.

 FPREShoot - (Vmax-Vtop)/Vamp before the

waveform falling transition.

TIME MEASUREMENT PARAMETERS

 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.

 +Wid - Time between the first rising edge and

the next rising edge at the waveform 50% level.

 -Wid - Time between the first falling edge and

the next rising edge at the waveform 50% level.

 Rise Time - Duration of pulse waveform's rising

transition from 10% to 90%, averaged for all rising
transitions between the cursors.

 Fall Time - Duration of pulse waveform's

falling transition from 90% to 10%, averaged for all
falling transitions between the cursors.

 BWid - Duration of a burst measured over the

entire waveform.

 +Dut - Ratio between positive pulse width and

period.

 -Dut - Ratio between negative pulse width and

period.
