WA1K2K-OM-E RevB 5

 Installation (Overvoltage) Categories II (Mains Supply Connector)

& I (Measuring Terminals).

 Pollution Degree 2.
 Protection Class I.

PLEASE NOTE THE FOLLOWING:

 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. Conductivity
caused by temporary condensation should be expected.

 Protection Class 1 refers to 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

The instrument relies on forced air cooling with an internal fan and
ventilation openings. Care must be taken to avoid restricting the airflow
around the apertures (fan holes) at the sides of the oscilloscope. Ensure
adequate ventilation by leaving the required 5 cm (2 inch) minimum gap
around the sides of the instrument.

CAUTION

Do not block the ventilation holes located on both sides of the
oscilloscope.

CAUTION

Do not allow any foreign matter to enter the oscilloscope through the
ventilation holes, etc.

AC Power Source

100 to 240 VAC (±10%) at 50/60/400 Hz (+10%); Installation Category:
300V CAT II

No manual voltage selection is required because the instrument
automatically adapts to line voltage.

Power Consumption

< 50 Watts for all models (depending on accessories installed - probes,
USB devices, etc.).

Power consumption in Standby Mode: < 5 Watts.

Power and Ground Connections

The instrument is provided with a 10A/250V 18AWG rated grounded
cord set containing a molded three-terminal polarized plug and a
standard IEC-60320 (Type C13) connector for making line voltage and
safety ground connections. 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.

WARNING - Electrical Shock Hazard

Only use the power cord provided with your instrument.

Any interruption of the protective conductor inside or outside of the
oscilloscope, or disconnection of the safety ground terminal creates a
hazardous situation. Intentional interruption is prohibited.

In Standby mode, the oscilloscope is still connected to the AC supply. The
instrument can only be placed in a complete Power Off state by flipping
the main power switch on the rear of the instrument (if provided) to the
off (Zero) position or by removing the power cord. In cases where no
main power switch is provided, removing the main power cord is the
disconnect device.

Vertical Settings and Channel Controls

Vertical Settings and Channel Controls

When you turn a channel trace ON, the Channel menu opens. The
Channel menu page shown (1/3, 2/3, or 3/3) is always based on the most

recent trace activated.

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.

Operator's Manual

28 WA1K2K-OM-E RevB

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.

1. Turn the Bandwidth Limit ON by activating the specific channel.

Press the desired channel button - CH1 or CH2 (or CH3 or 4 on 4

Acquisition Types

Acquisition Types

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 acquisition types:

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

construct the waveform.

Note: You can use this type to reduce random noise. This type does

not acquire rapid variation in the signal that may occur between
samples. This can result in narrow pulses being missed. In this case, use

Peak Detect 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 appears
higher in this mode.

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

displays the resulting waveform.

Note: This type can be used to reduce random noise.

Use the following steps to choose a sampling type.

1. Press the ACQUIRE front panel button. On the Acquire menu,

press the Acquisition option button and select a sampling type.

WaveAce 1000/2000

WA1K2K-OM-E RevB 35

2. If you select the Average sampling type, press the Averages option

button and select the number of waveforms (4, 16, 32, 64, 128, or

256).

Sinx/x

Choose Sinx or x by pressing the corresponding option button. This turns
Sinx/x on or off, respectively.

Sinx/x interpolation is suitable for reconstructing curved or irregular
wave shapes, especially when the sample rate is 3 to 5 times the system
bandwidth.

Mode Selection

You can choose between Equivalent Time Sampling and Real Time
Sampling settings.

Operator's Manual

36 WA1K2K-OM-E RevB

 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.

Select from the sampling settings by pressing the Mode option button
and selecting Real Time or Equ Time.

Sampling Rate

Adjust the sampling rate by pressing the Sa Rate option button and
turning the Time/div front panel knob. The sampling rate is shown at the
corresponding timebase scale.

WaveAce 1000/2000

WA1K2K-OM-E RevB 37

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.

Note: As you turn the Time/div front panel knob, the value is displayed at the

lower-center of the display as described in Understanding Display

Information (on page 22).

Zooming Waveforms

The Delayed option button on the Horizontal menu (or pressing the
Time/Div Front Panel (on page 10) knob) toggles between a state where

the display provides a split-screen layout where an upper trace shows the
actual waveform with a shaded, mask-like portion covering the non­zoomed portion of the waveform; the lower trace displays the actual
zoom segment. While in this view, turn the Push Zoom Front Panel (on
page 10) knob to adjust the zoom portion of the trace.

Analyzing Waveforms

Analyzing Waveforms

Four main front panel buttons are used for waveform analysis.

 Two Menu Function front panel buttons - Cursors, Measure
 The other two are Vertical front panel buttons - Math, REF

The following topics explain their detailed use.

Measuring with Cursors

Cursors are important tools that aid you in measuring signal values.
Cursors are boundary markers you can move across the grid. Use cursors
to make fast, accurate measurements and eliminate guesswork.

There are three cursor measurement modes:

1. Manual - displays two horizontal parallel cursors or vertical

parallel cursors to measure voltage or time, respectively.

Operator's Manual

46 WA1K2K-OM-E RevB

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.

Move cursors by pressing corresponding CurA, CurB option
buttons, and then using the Adjust front panel knob. Before using
cursors, you should make sure that you have set the signal source
as the channel for measuring.

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

position on the waveform automatically.

WaveAce 1000/2000

WA1K2K-OM-E RevB 47

You can adjust the cursor position on the waveform by turning the
Adjust front panel knob. Measurement values are shown in the
upper-left corner of the grid display.

3. 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.

 Measurement values are shown in the upper-left corner of the

grid display and are explained as follows:

Shown in Manual Cursor Mode

▲V - the vertical space between Cursor A and Cursor B (Voltage
value between the two cursors)

CurB - the horizontal position of Cursor B (in Volts)

CurA - the horizontal position of Cursor A (in Volts)

Shown in Track Cursor Mode

Operator's Manual

48 WA1K2K-OM-E RevB

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
on the channel ground level)

B→T - the horizontal position of Cursor B (Time cursor centered on
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)

Cursor Placement

CurB option button and turn the Adjust front panel knob to adjust
the cursors.
OR

Track

Set the mode to Track by pressing the Mode option button until
Track is selected. Press the Cursor A or Cursor B option button and
select a source of CH1, CH2 (also, CH3 and 4 on 4 channel models)
or NONE. Press the CurA or CurB option button and turn the
Adjust front panel knob to adjust the cursors. If Track is selected,
both cursors move in unison and appear slightly brighter on the
grid display.
OR

Auto

Set the mode to Auto by pressing the Mode option button until
Auto is selected. When you select measurement parameters using
the MEASURE front panel button, the cursors are automatically
displayed.

Note: When using Cursors, their measurement values are always shown in the

upper-left corner of the grid display. The cursor selected for placement is
indicated by a highlighted icon on the menu and the cursor itself has a higher
brightness on the grid display.

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 of your
waveform attributes, like rise time, rms voltage, and peak-to-peak
voltage, for example.

Access parameter measurements by pressing the MEASURE front panel
button. The main Measure menu is shown. Notice how each row on the

Operator's Manual

50 WA1K2K-OM-E RevB

Measure menu is labeled with a CHX, a Type, and a Value. Each row is a
customizable parameter measurement preset.

Press the corresponding option button to show additional preset controls
for Voltage, Time, Delay, and AllMea for the Source channel selected.

WA1K2K-OM-E RevB 51

Voltage Measurement Parameters

First select a Source Channel for your Voltage measurement parameter
by pressing the Source option button. Now, use the Type option button
to choose from the following Voltage measurement parameters for your
selected source.

 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.

Operator's Manual

52 WA1K2K-OM-E RevB

 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.
