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, 100MSa/s sample rate and up to 400,000 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. 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 4078 only optional GPIB interface 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 4075/4078 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. 4075 & 4078 2 10 MHz external reference w w w .b k p r ec is i o n .c o m 25 MHz Arbitrary / Function Generators Models 4075 & 4078 Flexible memory management Unlike other comparable generators, which typically contain only a few fixed-size memory locations for waveform storage, the 4075 and 4078 gives users more freedom - the 400000 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. Programmable Markers Models 4075 and 4078 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 25 MHz Arbitrary / Function Generators Models 4075 & 4078 Specifications 4075 Channels F r eq ue nc y Ch ar ac te ri stic s Sine Square Triangle, Ramp Pulse Accuracy Resolution A r b itr a ry C ha ra ct er is t ics Built-in Waveforms Waveform Length Vertical Resolution Noise Sampling Rate Frequency 1 Channel models 4078 2 Channels 1 Hz to 25 MHz 1 Hz to 25 MHz 1 Hz to 5 MHz 1 mHz to 10 MHz 0.002 % (20 ppm) 12 digits or 1 Hz Sine, Triangle, Square, Noise, Ramp Up, Ramp Down, Sine(X)/X, Exponential Up, Exponential Down, Gaussian 2 points to 400,000 points 14 bits (16,384 levels) Add 1% to 100% to output waveform 100 MSa/s, Point execution rate adjustable from 10 ns-50 s Accuracy: 0.005% (50 ppm) Resolution: 4 digits O u tp u t C ha ra c ter ist ic s Amplitude Range Amplitude Resolution Amplitude Accuracy (1 kHz) Flatness (relative to 1 kHz) Offset Range Offset Resolution Offset Accuracy Output Impedance Output Protection 10 mV to 10 Vp-p into 50 3 digits (1000 counts) 1% 1 mV 0.2 dB to 1 MHz 1 dB to 25 MHz 5 V into 50 , depending on the Amplitude setting 10 mV with 3 digits resolution 1% 10 mV into 50 50 typical The instruments output is protected against short circuit or nominal accidental voltages applied to the main output connector Triggered waveform cycle is limited to 10 MHz in ARB mode and 5 MHz in DDS mode.
