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 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.

ii
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
To minimize shock hazard, the instrument chassis and cabinet must be 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 three-conductor 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.

2Getting Started
Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.
2.1 Input Power Requirements
Input Power
The supply has a universal AC input that accepts line voltage and frequency input within:
100 – 240 V (+/- 10%), 50 – 60 Hz (+/- 5%)
100 – 127 V, 45 – 440 Hz
Before connecting to an AC outlet or external power source, be sure that the power switch is
in the OFF position and verify that the AC power cord, including the extension line, is
compatible with the rated voltage/current and that there is sufficient circuit capacity for the
power supply. Once verified, connect the cable firmly.
The included AC power cord is safety certified for this
instrument operating in rated range. To change a
cable or add an extension cable, be sure that it can
meet the required power ratings for this instrument.
Any misuse with wrong or unsafe cables will void the
warranty.
2.2 Output Connections
The waveform generator output circuits operate as a 50 Ω voltage source working into a 50
Ω load. At higher frequencies, a non-terminated or improperly terminated output may cause
aberrations on the output waveform. In addition, loads with an impedance less than 50 Ω
will reduce the waveform amplitude, while loads with an impedance greater than 50 Ω will
increase waveform amplitude.
Excessive distortion or aberrations caused by improper termination are less noticeable at
lower frequencies, especially with sine and triangle waveforms. To ensure waveform
integrity, follow these precautions:
1. Use good quality 50 Ωcoaxial cable and connectors.
2. Make all connections tight and as short as possible.
3. Use good quality attenuators, if it is necessary to reduce waveform amplitudes
applied to sensitive circuits.
4. Use termination or impedance-matching devices to avoid reflections.
5. Ensure that attenuators and terminations have adequate power handling
capabilities.

6
If there is a DC voltage across the output load, use a coupling capacitor in series with the
load. The time constant of the coupling capacitor and load must be long enough to maintain
pulse flatness.
Impedance Matching
If the waveform generator is driving a high impedance, such as a 1 MΩ input impedance
(paralleled by a stated capacitance) of an oscilloscope vertical input, connect the
transmission line to a 50 Ω attenuator, a 50 Ω termination and to the oscilloscope input. The
attenuator isolates the input capacitance of the device and terminates the waveform
generator properly.
2.3 Preliminary Check
Complete the following steps to verify that the generator is ready for use.
1. Verify AC Input Voltage
Verify and check to make sure proper AC voltages are available to power the
instrument. The AC voltage range must meet the acceptable specification as
explained in section 2.1.
2. Connect Power

end of the test, all function, menu, and channel output buttons will light
up, and all of their corresponding buttons in the silhouette on the display
will turn blue. Press 8to exit the test.
4. Self Adjust
This option runs an internal self adjustment procedure that will check and adjust the
instrument to specification. Use this option only if the instrument is suspected to be
out of calibration.
Press Utility, select More 1 of 2 from the menu to enter the second menu page, and
select Test/Cal option. Make sure nothing is connected to the instrument. Then,
select SelfAdjust option. The instrument will run the procedure internally, and a
progress bar will be displayed in the waveform information area. When finished, it
will show 100% on the progress bar and prompt you to press any function key to
