Additional Information

Working Principle

The PC transfers the waveform data to the memory of the signal generator via the USB bus, the ID counter cycles and sends the period waveform data to the DAC circuits, the DDS (Direct Digital Synthesized) circuit produces the corresponding DAC refreshing clock. The waveform of DAC is outputted through the Cache magnifier, Low Pass Filter, and the Magnifier. The frequency counter can test the external frequency.

Function Picture


Intended Use

The waveform generator connected to a Windows® computer with USB 2.0 port (USB 1.1 compatible) is used as a digital function generator 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 done using the measurement software enclosed. It is equivalent to a real oscilloscope operating interface. Via an import function, signal data in CSV format can be imported and these signals 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 is via the USB port.

Any use, other than that described above, could lead to damage to this product and involves the risk of short circuits, fire, electric shock, etc.

No part of the product should be modified or reassembled. Measurement in a damp location, outdoors or under adverse environmental conditions is not permitted.

Unfavorable ambient conditions are: – Wet conditions or high air humidity – Dust and flammable gases, vapors 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 and Danger Warnings

Please read the entire operating instructions before using the product for the first time; they contain important information about the correct operation.

The warranty will be void for damage arising from non-compliance with these operating instructions. Liability for any and all consequential damage is excluded!

We do not assume any liability for material and personal damage caused by improper use or non-compliance with the safety instructions! The warranty is voided in these 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 circuit before connecting them to the measuring circuit to be tested. After finishing the measurements, first of all disconnect the measurement leads from the circuit before you disconnect them from the unit.

Take particular care when dealing with voltages exceeding 25 V AC or 35 V 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 carry out 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!). Please make sure that your hands, shoes, clothing, the floor, the measuring instrument and the measurement lines, switches and switching parts are absolutely dry.

Do not use the product inside of rooms, or in poor ambient conditions, where flammable gases, vapours or explosive dust may be present or are present!

Do not use in the immediate proximity of strong magnetic or electromagnetic fields or transmission 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 operation 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 – if 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 environment. The condensation that forms might destroy your device. Allow the device to reach room temperature before switching it on.

Do not carelessly leave the packaging material lying around since this may become a dangerous toy for children.

In commercial and industrial facilities the regulations for the prevention of accidents as laid down by the professional trade association for electrical equipment and devices must be observed.

In schools, training centres, computer and self-help workshops, the use of measuring instruments 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.

Installing the Measurement Software

Before you connect the DSO (direct digital synthesis oscillator) to a computer, install the measurement software.

Switch on the computer and start the operating system.

Insert the provided software CD into the CD drive and close it. The automatic start mode will automatically start the installation of the measuring software.

If this does not happen automatically, start the program, setup.exe by double-clicking in Explorer of your operating system, on the drive holding the CD-ROM. The software installation will start.

The installation assistant will guide you through the installation. Please follow the on-screen instructions. In the start menu program manager, a new folder called 3005 USB is created.

Leave the CD in the drive for device installation (drivers).

Connection and Installation of the Unit

Connect the USB connection cable provided to 2 free USB ports on your computer and then to the USB connection (G) on the DDS.

The operating system recognizes the new hardware and starts the hardware assistant. Follow the instructions on the screen.

Choose the installation option. Install software automatically (recommended) and press Continue.

The system searches for the compatible driver. Follow the instructions on the screen until the installation is completed.

Starting the Measuring Software

Start the computer and connect the USB connector from the computer to the DSO (DDS) before starting the program.

Start the DDS-3005 USB program from the start menu or the desktop.

The start screen for the measuring software appears and initializes the DDS prefix. The DDS is ready.

System Requirements

Windows® computer minimum, Pentium® II or compatible with at least 64 kB RAM, VGA, CDROM, USB V2.0 (1.1 compatible), 40 MB free space on the hard disk, Windows® 98 SE or above.
