Arbitrary Function Generator
Prefix DDS-3005 USB
Item-No.12 29 24

Intended Use

The function generator prefix (also referred to as DDS prefix) is intended for connection to a
Windows® computer with USB 2.0 port (USB 1.1 compatible) for use as a digital function gen-
erator up to 5 MHz. Apart from the freely definable arbitrary functions, standard signals such as
sine, square, triangle, saw tooth, TTL, noise, trapezium, exponential function as well as AM and
FM are available. In addition, two frequency counter inputs (from DC - 25 MHz and from 25 MHz
- 2.7 GHz) as well as a digital 8 bit input and output can be used. Operation and display is per-
formed with the enclosed measurement software. It is equivalent to a real oscilloscope operat-
ing interface. Via an import function, signal data in CSV format can be imported and these sig-
nals can be regenerated without loss.
For simple initial operation, user defined appliance settings can be stored and called.
For safety reasons the input voltage of 25 Vpp must never be exceeded. Use partial probes, if
necessary. It may only be used in the excess voltage range, category CAT I, for signal voltages.
The voltage supply for the generator prefix is via two free USB ports.
Any other use than that described above, could lead to damage to this product and involves the risk
of short circuits, fire, electric shock, etc.
The product must not be changed or modified in any way. Do not open the housing!
Measurement in a damp locations, outdoors or under adverse environmentalconditions is not
permitted.
Unfavourable ambient conditions are:
- Wet conditions or high air humidity,
- Dust and flammable gases, vapours or solvent,
- Thunderstorms or similar conditions such as strong electrostatic fields etc.
Always observe the safety notes included in these operating instructions.
This quick guide explains the safety measures that should be taken to make working with the
device as safe as possible. The individual appliance functions are explained in detail in the
„Help" function of the measurement software.

Safety Instructions and Hazard Warnings

Please read all of the operating instructions before using the product for the first
time; they contain important information about the correct operation.
• The warranty will be void in the event of damage caused by failure to observe these safety
instructions! We do not assume any liability for any consequential damage!
• Nor do we assume any liability for material and personal damage caused by improper use or
non-compliance with the safety instructions! The warranty will be void in such cases.
• The unauthorized conversion and/or modification of the product is inadmissible because of
safety and approval reasons (CE).
• All earth connections of the measuring inputs are directly connected to the earth of the USB
connector.
• Measurement devices and accessories should be kept away from children! Therefore, be
especially careful when children are around.
• Connect the measuring lines to the DDS circuit, before connecting them to the measuring cir-
cuit to be tested. After finishing the measurements, first disconnect the measurement leads
from the circuit before you disconnect them from the DDS prefix.
• Take particular care when dealing with voltages exceeding 25V AC or 35V DC! Even at such
voltages you can receive a life-threatening electric shock if you come into contact with live
electric wires.
• Prior to each measurement, check your instrument and its measuring leads for damage.
Never make any measurements if the protecting insulation is defective (torn, missing etc.)
• To avoid electric shock, do not to touch the connections/measuring points directly or indirectly
during measurements.
• Do not use the appliance shortly before, while or shortly after a thunderstorm (lightning!/ over
voltage!). Make sure that your hands, shoes, clothing, the floor, the measuring device and/or
measuring lines, the circuits and its parts are always dry.

• Do not use the product inside of rooms, or in poor ambient conditions, where flammable gas-
es, vapours or explosive dust may be present or are present!
• Do not use in the immediate proximity of strong magnetic or electromagnetic fields or trans-
®
mission aerials. These can affect the measurement.
• If you have reason to assume that safe operation is no longer possible, disconnect the device
immediately and secure it against inadvertent operation. It can be assumed that safe opera-
tion is no longer possible if:
- the device is visibly damaged,
- the device no longer works and
- the unit was stored under unfavourable conditions for a long period of time or
- it has been subjected to considerable stress in transit
• Never switch the device on immediately after having taken it from a cold in to a warm environ-
ment. The condensation that forms might destroy your device. Allow the device to reach room
temperature before switching it on.
• Do not leave packing materials unattended. They may become dangerous playthings for chil-
dren.
• On industrial sites, the accident prevention regulations of the association of the industrial work-
ers' society for electrical equipment and utilities must be followed.
• In schools, training centres, computer and self-help workshops, the use of measuring instru-
ments and accessories must be supervised by trained personnel in a responsible manner.
• Consult qualified staff, if you have doubts about how the equipment operates or about how to
connect it safely.
• Handle the product with care. The product can be damaged if crushed, struck or dropped,
even from a low height.
• Pay attention to the detailed operating instructions in the measurement program (Help).
This device left the manufacture's factory in a safe and perfect condition.
We kindly request the user to observe the safety instructions and warnings contained in the
enclosed operating instructions so this condition is maintained and to ensure safe operation.
Please pay attention to the following symbols:
A triangle containing an exclamation mark, in these operating instructions, indicates
important information that has to be observed without fail.
The „hand" symbol is used to indicate where specific hints and information on handling
are given.
This product has been CE-tested and meets the required European guidelines.
Never operate the measuring device when it is open. !RISK OF F
ATAL INJURY!
Do not exceed the maximum permitted input values. Never touch circuits or
parts of circuits with voltages greater than 25 V/AC rms or 35 V/DC! Danger to
life!
When using partial probes, the active measuring circuit must always be placed
against the internal conductor (probe head).
