Function Generators
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 200 MHz. Increase your productivity with the included
intuitive Windows Software: Create 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 (fig1).
Additionally, the software provides a direct interface to
Tektronix
®
TDS1000, TDS2000 TPS2000 and TDS3000 series
digital storage oscilloscope. 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.
