4084AWG

Data Sheet 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.
