Arbitrary/Function Generators
Models 4084AWG & 4086AWG
The B&K Precision® 4084AWG and 4086AWG are high performance
laboratory grade synthesized function generators with arbitrary capability.
Direct digital synthesis (DDS) techniques are used to create stable,
accurate output signals for all 27 built-in standard and complex (arbitrary)
waveforms. The generators produce high purity, low distortion sine waves
up to 80 MHz, square waves up to 40 MHz and a stable output of very
small signals down to the 1mV - 10mV range. The instrument also provides a built-in 100 MHz Universal Counter with frequency measurement
and totalize function.
Unmatched affordability and excellent performance make models
4084AWG & 4086AWG a perfect fit for many applications in Electronic
Test and Design, Sensor Simulation and Education and Training.
Custom waveform generation made easy
In addition to the built-in complex waveforms, you can use the
4084AWG & 4086AWG to generate custom arbitrary waveforms with
10 bit vertical resolution, 16k memory depth and a sample rate of
200MSa/s. Increase your productivity with the included intuitive Windows
Software: Generate and edit waveforms and download them to the instrument with a single click. Waveforms can be generated in many ways:
Draw waveforms freehand, import them from a text file or start out with
standard functions and customize them with the provided math functions
(Fig. 1).
Additionally, the software provides a direct interface to Tektronix®
TDS1000, TDS2000 TPS2000 and TDS3000 series digital storage
oscilloscopes. Users can easily import waveforms originating from the
DSO’s display or internal memory and download and "replay" them on
the instrument.
Versatile modulation and trigger capabilities
The generators provide extensive modulation capabilities including AM,
FM, FSK, PSK, pulse modulation and linear/logarithmic sweep.
Internal and external modulation sources, as well as internal, external
and gated trigger sources are supported. Modulation parameters can
be set precisely and are adjustable over a wide range. For instance,
burst count is programmable in 1 burst increments up to 10000 bursts
and burst phase is adjustable in 0.1º increments.
Convenient user interface and operation
You can adjust parameters via knob or numeric keypad. Enter amplitude values directly in Vpp, mVpp, Vrms, mVrms or dBm, and display
the correct voltage by entering the actual output configuration used
(terminated with 50 Ohm or open circuit). You can enter frequency in
terms of frequency or seconds using time values s, ms, Hz, kHz or
MHz. Submenus are used for modulation modes and other complex
functions. The generators are fully programmable via the standard
RS232 interface, using SCPI commands. The instrument also provides
10 memories to store and recall instrument settings. Additionally the
current state is saved at power off and can be restored at power up.
