2 Introduction
Description
The B&K Precision model 4005DDS is a versatile 5 MHz DDS (direct digital synthesis)
function generator with display up to 4 digits. The instrument generates sinusoidal,
triangular, and square waveforms over the 1 Hz to 5 MHz range. The output voltage
can be varied from 0 to 10 Vp-p into 50 ohms or to 20 Vp-p into open circuit. A
continuously variable DC offset allows the output to be injected directly into circuits
at the correct bias level.
Features
 Frequency is selectable from 1 Hz to 5 MHz
 Sine, square, or triangle waveform output
 Direct digital synthesis (DDS) architecture
 Bright, easy-to-read LED display
 Number pad for quick input of frequency
 Front panel push button and pull knob can attenuate output by up to 40 dB
3 Installation
3.1 Initial Inspection
This unit is tested prior to shipment. It is therefore ready for immediate use upon
receipt. The initial physical inspections should be made to ensure that no damage has
been sustained during shipment.
Inspect the packing box on receipt for any external damage. If any external damage is
evident, remove the instrument and visually inspect its case and parts for any
damage. If damage to the instrument is evident, a description of the damage should
be noted on the carrier’s receipt and signed by the driver or carrier agent. Save all
shipping packaging for inspection and contact the distributor from where the
instrument was purchased.
