Safety Summary

The following safety precautions apply to both operating and maintenance
personnel and must be followed during all phases of operation, service,
and repair of this instrument.

Before applying power to this instrument:

 Read and understand the safety and operational information in

this manual.

 Apply all the listed safety precautions.
 Verify that the voltage selector at the line power cord input is set

to the correct line voltage. Operating the instrument at an
incorrect line voltage will void the warranty.

 Make all connections to the instrument before applying power.
 Do not operate the instrument in ways not specified by this

manual or by B&K Precision.

Failure to comply with these precautions or with warnings elsewhere in
this manual violates the safety standards of design, manufacture, and
intended use of the instrument. B&K Precision assumes no liability for a
customer’s failure to comply with these requirements.

Category rating

The IEC 61010 standard defines safety category ratings that specify the
amount of electrical energy available and the voltage impulses that may
occur on electrical conductors associated with these category ratings. The
category rating is a Roman numeral of I, II, III, or IV. This rating is also
accompanied by a maximum voltage of the circuit to be tested, which
defines the voltage impulses expected and required insulation clearances.
These categories are:

Category I (CAT I): Measurement instruments whose measurement inputs
are not intended to be connected to the mains supply. The voltages in the
environment are typically derived from a limited-energy transformer or a

i

battery.

Category II (CAT II): Measurement instruments whose measurement inputs
are meant to be connected to the mains supply at a standard wall outlet or
similar sources. Example measurement environments are portable tools
and household appliances.

Category III (CAT III): Measurement instruments whose measurement
inputs are meant to be connected to the mains installation of a building.
Examples are measurements inside a building's circuit breaker panel or the
wiring of permanently-installed motors.

Category IV (CAT IV): Measurement instruments whose measurement
inputs are meant to be connected to the primary power entering a
building or other outdoor wiring.

Do not use this instrument in an electrical environment with a higher
category rating than what is specified in this manual for this instrument.

You must ensure that each accessory you use with this instrument has a
category rating equal to or higher than the instrument's category rating to
maintain the instrument's category rating. Failure to do so will lower the
category rating of the measuring system.

Electrical Power

This instrument is intended to be powered from a CATEGORY II mains
power environment. The mains power should be 120 V RMS or 240 V RMS.
Use only the power cord supplied with the instrument and ensure it is
appropriate for your country of use.

Ground the Instrument

connected to an electrical safety ground. This instrument is grounded
through the ground conductor of the supplied, three-conductor AC line
power cable. The power cable must be plugged into an approved three­conductor electrical outlet. The power jack and mating plug of the power
cable meet IEC safety standards.

Do not alter or defeat the ground connection. Without the safety ground
connection, all accessible conductive parts (including control knobs) may
provide an electric shock. Failure to use a properly-grounded approved
outlet and the recommended three-conductor AC line power cable may
result in injury or death.

Unless otherwise stated, a ground connection on the instrument's front or
rear panel is for a reference of potential only and is not to be used as a
safety ground.

Probe Safety

SHOCK HAZARD

To avoid electric shock when using the probe, keep fingers
behind the guard on the probe body.

To avoid electric shock while using the probe, do not touch
metallic portions of the probe head while it is connected to a
voltage source. Connect the probe to the oscilloscope and
connect the ground terminal to ground before you take any
measurements.

A guard around the probe body provides a finger barrier for protection
from electric shock.

Figure 2.5 – Oscilloscope Probe

Connect the probe to the oscilloscope and connect the ground terminal to
ground before you take any measurements.

10

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

Probe Attenuation

NOTE: The default setting for the Probe option is 1X.

NOTE: When the attenuation switch is set to 1X, the probe limits

the bandwidth of the oscilloscope to 6 MHz (according to Probe
spec). To use the full bandwidth of the oscilloscope, be sure to set

the switch to 10X

Probes are available with various attenuation factors which affect the
vertical scale of the signal. The Probe Check function verifies that the
Probe attenuation option matches the attenuation of the probe.

You can push a vertical menu button (such as the CH 1 MENU button), and
select the Probe option that matches the attenuation factor of your probe.

Be sure that the attenuation switch on the probe matches the Probe
option in the oscilloscope. Switch settings are 1X and 10X.

Probe Compensation

As an alternative method to Probe Check, you can manually perform this
adjustment to match your probe to the input channel.

However, the magnitude information near or above the
bandwidth will not be accurate.

• “GND” Coupling: Use GND coupling to display a zero-volt

waveform. Internally, the channel input is connected to a zero­volt reference level.

• Fine Resolution: The vertical scale readout displays the actual

Volts/Div setting while in the fine resolution setting. Changing the
setting to coarse does not change the vertical scale until the
VOLTS/DIV control is adjusted.

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 signal.

Setting up Channels

Each channel has its own separate Menu. The items are set up separately
according to each channel.

1. Setup Channel Coupling

Take CH1 for example; the tested signal is a sine wave signal with
DC deflection:

• Press “CH1”→“Coupling”→“AC”, Set to AC couple mode.

This will block the DC component of the input signal.

• Press “CH1”→“Coupling”→“DC”, Set to DC couple mode.

Both DC and AC components of the input signal will be
captured.

28

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

• Press “CH1”→“Coupling”→“GND”, Set to GROUND

mode. This disconnects the input signal.

2. Bandwidth Limiting

Take CH1 for example:

• Press “CH1”→“BW Limit”→ “On”, and bandwidth will be

limited to 20 MHz.

• Press “CH1”→“BW Limit”→ “Off”, and bandwidth limit

will be disabled.

3. Volts/Div Settings

Vertical scale adjust have Coarse and Fine modes, Vertical
sensitivity range of 2 mV/div – 10 V/div.
Take CH1 for example:

• Press “CH1”→“Volts/Div”→“Coarse”. It is the default

setting of Volts/Div, and makes the vertical scaling in a 1­2-5-step sequence from 2 mV/div, 5 mV/div, and 10
mV/div to 10 V/div.

• Press “CH1”→ Volts/Div”→ Fine”. This setting changes

the vertical control to small steps between the coarse
settings. It will be helpful when you need to adjust the
waveform vertical size in smaller steps.

4. Setting Probe Attenuation

In order to set the attenuation coefficient, you need to specify it
in the channel operation Menu. If the attenuation coefficient is
10:1, the input coefficient should be set to 10X, so that the
Volts/div information and measurement testing is correct.
Take CH1 for example, when you use the 100:1 probe:

that the YT waveform repeats forever. With an integral number of cycles,
the YT waveform starts and ends at the me amplitude and there are no
discontinuities in the signal shape A non-integral number of cycles in the
YT waveform causes the signal start and end points to be at different
amplitudes. The transitions between the start and end points cause
discontinuities in the signal that introduce high-frequency transients.

Table 3.31 – Acquire Function Menu

When you acquire a signal, the oscilloscope converts it into digital form
and displays a waveform. The acquisition mode defines how the signal is
digitized and the time base setting affects the time span and level of detail
in the acquisition.

 Sampling: In this acquisition mode, the oscilloscope samples

the signal in evenly spaced intervals to construct the waveform.
This mode accurately represents signals most of the time.
Advantage: You can use this mode to reduce random noise.

70

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

Disadvantage: This mode does not acquire rapid variations in the
signal that may occur between samples. This can result in aliasing
may cause narrow pulses to be missed. In these cases, you should
use the Peak Detect mode to acquire data.

Figure 3.30 – Acquire Menu

 Peak Detect: Peak Detect mode capture the maximum and

minimum values of a signal Finds highest and lowest record
points over many acquisitions.
Advantage: In this way, the oscilloscope can acquire and display
narrow pulses, which may have otherwise been missed in Sample
mode.
Disadvantage: Noise will appear to be higher in this mode.

71

 Average: The oscilloscope acquires several waveforms, averages

them, and displays the resulting waveform.
Advantage: You can use this mode to reduce random noise.

72

Figure 3.32 – Average Acquisition

 Equivalent Time Sampling: The equivalent time sampling mode

can achieve up to 20 ps of horizontal resolution (equivalent to
50GSa/s). This mode is good for observing repetitive waveforms.

 Real Time Sampling: The scope has a maximum Real-time

sampling rate of 1GSa/s.

 “RUN/STOP” Button: Press the RUN/STOP button when you want

the oscilloscope to acquire waveforms continuously. Press the
button again to stop the acquisition.

 “SINGLE” Button: Press the SINGLE button to acquire a single

waveform. Each time you push the SINGLE button, the
oscilloscope begins to acquire another waveform. After the
oscilloscope detects a trigger it completes the acquisition and
stops.
When you push the RUN/STOP or SINGLE buttons to start an
acquisition, the oscilloscope goes through the following steps:

1. Acquire enough data to fill the portion of the waveform

record to the left of the trigger point. This is also called
the pre-trigger.

2. Continue to acquire data while waiting for the trigger

waveform due to aliasing

Actual high-frequency waveform

condition to occur.

3. Detect the trigger condition.

4. Continue to acquire data until the waveform record is

full.

5. Display the newly-acquired waveform.

 Time Base: The oscilloscope digitizes waveforms by acquiring the

value of an input signal at discrete points. The time base allows
you to control how often the values are digitized. To adjust the
time base to a horizontal scale that suits your purpose, use the
Time/div knob.

 Time Domain Aliasing: Aliasing occurs when the oscilloscope

does not sample the signal fast enough to construct an accurate
waveform record. When this happens, the oscilloscope displays a
waveform with a frequency lower than the actual input
waveform, or triggers and displays an unstable waveform.

3.14 Measure System

The oscilloscope displays the voltage in relation to time and tests the
waveform displayed. Different measurement techniques such as scale,
Cursor and auto measure modes are used.

Scale Measurement

This method allows you to make a quick, visual estimate. For example, you
might look at waveform amplitude and determine that it is a little more
than 100 mV. You can take simple measurements by counting the major
and minor graticule divisions involved and multiplying by the scale factor.
For example, if you counted five major vertical graticule divisions between
the minimum and maximum values of a waveform and knew you had a
scale factor of 100 mV/div, then you could easily calculate your peak-to­peak voltage as follows:

5 𝑑𝑖𝑣𝑖𝑠𝑖𝑜𝑛𝑠 ×

Auto Measurement

When you take automatic measurements, the oscilloscope does all the
calculation for you. The measurements use all the recorded points in the
memory, which are more accurate than measurements made using the
graticule lines or cursor measurements because these measurements are
confined to be made by only using points on the display and not all the
data points recorded by the oscilloscope.

Press the ‘MEASURE’ button for Automatic Test.

There are three auto measurement types: Voltage Measure, Time
Measure, and Delay Measure. There are a total of 32 measurement
parameters.
