  • Welcome to the training module on ArbStudio Arbitrary Waveform Generators.
  • This training module will introduce ArbStudio Arbitrary Waveform Generators.
  • Designing, testing, troubleshooting, or repairing circuits or electronic products require signal stimuli varying from advanced communication signals to the playback of captured real-world analog signals. Unlike an oscilloscope is then used to measure the circuit's output, the arbitrary waveform generator is used as signal source to generate the signal stimulus that is applied to a device under test. The variety of waveforms that may be synthesized with an AWG can be broadly categorized into four categories: standard functions, advanced functions, arbitrary waveforms, and waveform sequences.
  • The ArbStudio series of arbitrary waveform generators (AWG) capable of generating signals up to 125 MHz with high sample rate, long memory and high resolution as well as a variety of operating modes, modulation capabilities and a digital pattern generator. The software interface that controls the hardware is designed to simplify waveform creation with an intuitive navigation tree which allows easy access to all channels along with special views for controlling basic function generator outputs as well as pulse width modulation (PWM) capabilities. The ability to have 2 and 4 channel units in a single, compact form factor not only saves bench space but also provides a low price per channel. Additionally the 4 channel ArbStudio models have an expansion port that allows up to 8 units to be connected, providing up to 32 synchronous analog waveforms.
  • Unlike other arbitrary waveform generators, the ArbStudio line doesn’t have a display on its front panel. ArbStudio has implemented these systems with USB connection to a PC, which serves as the user interface. Using the PC for display and interface functions enabled ArbStudio to build more performance into these instruments at a price point that’s similar to standalone instruments. 
  •   The ArbStudio software runs on an external PC freeing the user from the small displays and readouts found on a typical AWG. A simple function generator window is available for basic waveform creation while a unique, streamlined control panel dedicated for PWM signals is also available. The main software mode provides a start page that provides tutorials on creating a wide range of both simple and complex waveforms, as well as shortcuts to recent projects and an intuitive navigation tree to get started quickly. Once waveform creation has begun, graphical displays show the waveforms that have been created or sequenced and the views can be customized to only show the windows that are of most interest to the user.
  • Arbitrary waveform generators are typically available with one of two technologies, either True Arbitrary or Direct Digital Synthesis (DDS). Each of these modes comes with advantages and disadvantageous that force the user to think about what they need from an AWG. ArbStudio however does not have this limitation; it provides both modes and allows the user to choose which mode is needed for their waveforms. Furthermore, ArbStudio channels can be set to any mode independently of each other for the ultimate in flexibility. For complex modulation, DDS mode is the better choice. For more complex waveforms without modulation, the true arbitrary mode fills the bill. Either can be used at any time in different channels.
  • Many systems have a variety of analog and digital signals yet most waveform generators provide only analog outputs. The ArbStudio 1102D and 1104D models provide analog and digital pattern generation with 18 or 36 channels respectively. In this working mode ArbStudio 1102/1104 provides the capability to emulate standard serial or parallel bus transitions or custom digital interfaces for system debugging and characterization.
  • The modulation editor provides easy-to-use tools to configure the modulation scheme for any application. Creating PWM signals has never been easier thanks to a dedicated control panel designed just for PWM waveforms. Easily set modulation shape, duty cycle and all other aspects of the PWM plus configure different settings for each channel. The PWM control panel gives users an easy way to create complex PWM waveforms without having to resort to building them in the generator. The PWM mode is very handy for designers working on fan or motor control systems.
  • Here we show the 4 different AWGs under ArbStudio product line.
