Safety Summary
The following safety precautions apply to both operating
and maintenance personnel and must be observed
during all phases of operation, service, and repair of this
instrument. Before applying power, follow the installation
instructions and become familiar with the operating
instructions for this instrument.
If this device is damaged or something is missing,
contact the place of purchase immediately.
This manual contains information and warnings that
must be followed to ensure safe operation as well as
maintain the meter in a safe condition.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and
cabinet must be connected to an electrical ground. This
instrument is grounded through the ground conductor of
the supplied, three-conductor ac power cable. The
power cable must be plugged into an approved three-
conductor electrical outlet. Do not alter the ground
connection. Without the protective ground connection,
all accessible conductive parts (including control knobs)
can render an electric shock. The power jack and
mating plug of the power cable must meet IEC safety
standards.
DO NOT OPERATE IN AN EXPLOSIVE
ATMOSPHERE
Do not operate the instrument in the presence of
flammable gases or fumes. Operation of any electrical
instrument in such an environment constitutes a definite
safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Instrument covers must not be removed by operating
personnel. Component replacement and internal
adjustments must be made by qualified maintenance

3
personnel. Disconnect the power cord before removing
the instrument covers and replacing components.
Under certain conditions, even with the power cable
removed, dangerous voltages may exist. To avoid
injuries, always disconnect power and discharge circuits
before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt any internal service or adjustment unless
another person, capable of rendering first aid and
resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE
INSTRUMENT
Do not install substitute parts or perform any
unauthorized modifications to this instrument. Return
the instrument to B&K Precision for service and repair to
ensure that safety features are maintained.
WARNINGS AND CAUTIONS
WARNING and CAUTION statements, such as the
following examples, denote a hazard and appear
throughout this manual. Follow all instructions
contained in these statements.
A WARNING statement calls attention to an operating
procedure, practice, or condition, which, if not followed
correctly, could result in injury or death to personnel.
A CAUTION statement calls attention to an operating
procedure, practice, or condition, which, if not followed
correctly, could result in damage to or destruction of part
or all of the product.
WARNING:
Do not alter the ground connection. Without the
protective ground connection, all accessible
conductive parts (including control knobs) can
render an electric shock. The power jack and mating
plug of the power cable meet IEC safety standards.

WARNING:
To avoid electrical shock hazard, disconnect power
cord before removing covers. Refer servicing to
qualified personnel.
CAUTION:
Before connecting the line cord to the AC mains,
check the rear panel AC line voltage indicator.
Applying a line voltage other than the indicated
voltage can destroy the AC line fuses. For continued
fire protection, replace fuses only with those of the
specified voltage and current ratings.
CAUTION:
This product uses components which can be
damaged by electro-static discharge (ESD). To avoid
damage, be sure to follow proper procedures for
handling, storing and transporting parts and
subassemblies which contain ESD-sensitive
components.

1 Introduction
1.1 Introduction
This manual contains information required to operate the
B&K Precision model 4007B and 4013B DDS Function
Generators. This section covers the instrument’s general
description, specifications and characteristics.
1.2 Description
The 4007B and 4013B are versatile high performance
function generators. Implemented using a DDS (direct
digital synthesis) architecture, these instruments
generate stable and precise sine, square, and triangle
waveforms. Both models also provide linear and
logarithmic sweep for users needing sweep capability. An
auxiliary TTL output at the generator’s frequency is
available to synchronize external devices. Up to 9 front
panel settings can be saved to memory storage.

physical damage that may have occurred during
transportation. Report any damage to the shipping agent
immediately. Save the original packing carton for
possible future reshipment. Every generator is shipped
with the following contents:

2.4 Instrument Mounting
The 4007B and 4013B Function Generators are intended
for bench use. The instrument includes a front feet tilt
mechanism for optimum panel viewing angle. The
instrument does not require special cooling when
operated within conventional temperature limits. It may
be installed in a closed rack or test station if proper air
flow can assure removing about 15 W of power
dissipation.
2.5 Power Requirements
The 4007B and 4013B can be operated from any source
of 90V to 264V AC, frequency from 48Hz to 66Hz. The
maximum power consumption is 25 VA. Use a slow blow
fuse of 1A, UL/CSA approved as indicated on the rear
panel of the instrument.
The instrument power fuse is located in the AC input
plug. To access the fuse, first disconnect the power cord
and then remove the fuse cartridge.
2.6 Fuse Replacement
There is a 1A, 250V rated slow blow fuse at the AC input.
Should the fuse ever get blown, follow the steps below to
replace:

16
1. Locate the fuse box next to the AC input connector in
the rear panel.
2. With a small flat blade screwdriver, insert into the fuse
box slit to pull and slide out the fuse box as indicated
below.
3. Check and replace fuse if necessary.
2.7 Grounding Requirements
For the safety of operating personnel, the instrument
must be grounded. The central pin on the AC plug
grounds the instrument when properly connected to the
ground wire and plugged into proper receptacle.
WARNING
TO AVOID PERSONAL INJURY DUE TO SHOCK,
THE THIRD WIRE EARTH GROUND MUST BE
CONTINUOUS TO THE POWER OUTLET. BEFORE
CONNECTION TO THE POWER OUTLET, EXAMINE
ALL CABLES AND CONNECTIONS BETWEEN THE
Fuse box slit

2.8 Signal Connections
Use RG58U 50Ωor equivalent coaxial cables for all input
and output signals to and from the instrument.

3.2 Display Window
The function generator has a graphic LCD display that can
display up to 124 x 32 dots. When you power-on the unit sine
waveform is selected and current settings appear in the
display. The bottom displays a menu (selectable with function
keys) that corresponds to the function, parameter or mode
display selected.
3.3 Front Panel Controls
The front-panel controls select, display, and change parameter,
function, and mode settings.
Use the numerical keypad, rotary input knob and the cursor
movement keys to enter data into the waveform generator.
To change a setting:

20
1.Press the key that leads to the item to change.
2. Move cursor using cursor keys to the appropriate position in
the numeric field (if applicable).
3. Use the rotary input or the numerical keyboard to change the
value of the displayed item. Changes take effect immediately.
3.4 Connectors
The function generator has two BNC connectors on the front
panel where you can connect coaxial cables. These coaxial
cables serve as carrier lines for output signals delivered from
the function generator.
Output
Use this connector to transfer the main output signal from the
function generator.
Sync Out
Use this connector to output a positive TTL sync pulse
generated at each waveform cycle.
3.5 Output Connections
The waveform generator output circuits operate as a 50
Ωvoltage source working into a 50 Ωload. At higher
frequencies, non terminated or improperly terminated
output causes aberrations on the output waveform. In
addition, loads less than 50 Ωreduce the waveform
amplitude, while loads more than 50 Ωincrease
waveform amplitude.
Excessive distortion or aberrations caused by improper
termination are less noticeable at lower frequencies,
