Safety Summary

The following safety precautions apply to both operating and maintenance personnel and must be
observed during all phases ofoperation,service, and repair ofthis instrument. Before applying power,
follow the installation instructions and become familiar with the operating instructions for this
instrument.

Failure to comply with these precautions or with specific warnings elsewhere in this manual violates
safety standards ofdesign, manufacture, and intended use ofthe instrument. B&K assumes no liability for
a customer’s failure to comply with these requirements. This is a Safety Class I instrument.

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 ofthe 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 ofthe power
cable meet IEC safety standards.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

Do not operate the instrument in the presence offlammable gases or fumes. Operation ofany 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 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 ofrendering first aid and
resuscitation, is present.

Do not install substitute parts or performany unauthorized modifications to this instrument. Return the
instrument to vendor 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, ifnot

followed correctly,could result in injury or death to personnel.
A CAUTION statement calls attention to an operating procedure, practice, or condition, which, ifnot

followed correctly,could result in damage to or destruction ofpart or all ofthe 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.

Introduction

1.1 SCOPE

This manual contains installation instructions, test procedures, operation procedures and
troubleshooting information required to operate, test and maintain the Model 4007DDS Function
Generator.

1.2 DESCRIPTION

The Model 4007DDS is a versatile, high performance function generator. Implemented using
advance digital technologies based on DDS topology, the units generates superb quality waveforms
with high precision and stability.

It provides sine & square wave outputs over the frequency range from 0.1 Hz to 7 MHz in one
extended range (triangle/ramped wave outputs to 100KHz).

An auxiliary TTL output at the generator frequency is available to synchronize external devices.
The output voltage can be varied from 0V to 10V peak-to-peak into 50 ohms or to 20V into open
circuit. A front panel pushbutton can attenuate the output by 20 dB. The DC level of the output
can be adjusted using the offset control.
