The generators combine the ability to produce nearly any conceivable arbitrary waveform with accuracy and precision and a DDS architecture offering easy to use conventional function generator capabilities. Arbitrary waveforms have 14 bit amplitude resolution, 125 MSa/s sample rate and up to 4,000,000 points length. Waveforms can be output in continuous, triggered, gated or burst modes. Front panel operation is straightforward and user-friendly. The instruments can be remotely controlled using SCPI-compliant commands via RS232 or GPIB interface. ■ Both channels offer full functionality. All wave form parameters such as frequency, amplitude and offset can be set independently ■ Synchronize both output signals to the same clock signal (external or internal) and precisely adjust the phase relationship between the two signals Extensive features such as internal or external AM, FM and FSK modulation along with versatile sweep capabilities and variable edge pulse generation make these generators suitable for a wide range of applications including electronic design, sensor simulation, functional test or generation of I/Q modulated signals.

Arbitrary waveform editing and definition is flexible and easy: Waveforms can be defined from scratch by entering data point by point, by loading and modifying predefined built-in waveforms or by downloading waveforms via the remote interface, using either the included arbitrary waveform generation software Wave-X or a custom program. Standard function generator waveforms sine, square, ramp and pulse can be created by pressing a single button. ▲ Rear panel 4079 only 10 MHz external reference Flexible interface Built-in 10 MHz external reference is included at no extra cost (both models). This input/output let’s you synchronize with another 4076/4079 generator or to an external 10 MHz Clock for precise phase adjustment. Connect the programmable marker Output to the Trigger input of additional generators to create complex polyphase scenarios. 4076 & 4079 2 GPIB & RS-232 interface (standard) w w w .b k p r ec is i o n .c o m 50 MHz Arbitrary / Function Generators Models 4076 & 4079 Flexible memory management Unlike other comparable generators, which typically contain only a few fixed-size memory locations for waveform storage, the 4076 and 4079 gives users more freedom - the 4,000,000 point flash memory can be allocated to one large waveform or up to 50 different waveforms, each with a customizable length. Versatile noise generation In Arb mode you can conveniently add noise to your waveform directly from the front panel and precisely adjust the scale of the noise amplitude. Unlike other generators that only produce a noise waveform, this feature allows you to choose between generating a noise waveform or adding noise to an existing waveform. Waveform Summing The Summing Input on the rear panel allows waveforms from external signal sources to be summed with the output signal of the 4076 or 4079. Programmable Markers Models 4076 and 4079 provide fully programmable markers, allowing you to generate a positive TTL level output signal at the points specified by address and length up to 4000 points. This feature is available in Arbitrary mode and can not be found in other comparable waveform generators. It could be used for applications requiring polyphase signal generation, e.g. simulation of a real world 3 phase AC network where one of the phases is degraded with spikes or noise. Generate waveforms with ease The included PC Software allows you to easily generate, edit and download custom arbitrary waveforms. Generate waveforms by importing a textfile, or define via freehand, point draw or waveform math. Waveforms can also be uploaded from the generator for documentation purposes. 3 w w w .b k p r ec is i o n .c o m 50 MHz Arbitrary / Function Generators Models 4076 & 4079 Specifications 4076 models 4079 Channels 1 Channel 2 Channels F r eq ue nc y Ch ar ac te ri stic s Sine 1 µHz to 50 MHz Square 1 µHz to 50 MHz Triangle, Ramp 1 µHz to 5 MHz Pulse 0.5 mHz to 25 MHz Accuracy 0.001 % (10 ppm) Resolution 12 digits or 1 µHz A r b itr a ry C ha ra ct er is t ics Built-in Waveforms Sine, Triangle, Square, Noise, Ramp Up, Ramp Down, Sine(X)/X, Exponential Up, Exponential Down, Gaussian Waveform Length 2 points to 4,000,000 points Vertical Resolution 14 bits (16,384 levels) Noise Add 1% to 100% to output waveform Sampling Rate 125 MSa/s, Point execution rate adjustable from 8 ns-100 s Frequency Accuracy: 0.005% (50 ppm) Resolution: 4 digits or 1 ps O u tp u t C ha ra c ter ist ic s Amplitude Range 10 mV to 10 Vp-p into 50 Ω Amplitude Resolution 3 digits (1000 counts) Amplitude Accuracy (1 kHz) ± 1% ± 20 mV of programmed output from 1 V – 10 V Flatness (relative to 1 kHz) ± 0.1 dB to 10 MHz ± 1 dB to 50 MHz Offset Range ± 4.99 V into 50 Ω, depending on the Amplitude setting Offset Resolution 10 mV with 3 digits resolution Offset Accuracy ± 1% ± 10 mV into 50 Ω Output Impedance 50 Ω typical Output Protection The instrument’s output is protected against short circuit or nominal accidental voltages applied to the main output connector Filter 9 pole Elliptic and 5 pole Bessel filters W ave for m Ch ar ac t eri stic s Harmonic Distortion (sine) DC-20 kHz, -65 dBc 20 kHz-100 kHz, 60 dBc 100 kHz-5 MHz, -45 dBc 5 MHz-50 MHz, -35 dBc Spurious (sine) DC-1 MHz < -65 dBc Rise/Fall Time (square, pulse) < 6 ns (10% to 90%) at full amplitude into 50 Ω Variable Duty Cycle 20% to 80% to 10 MHz (square) 40% to 60% to 30 MHz (square) 50% >30 MHz (square) Variable Symmetry 10%-90% to 5 MHz (triangle) Symmetry at 50% < 0.5 % Linearity (triangle, ramp)
