LeCroy has débuted 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 eight units to be connected, providing up to 32 synchronous analog waveforms.
Four ArbStudio models are available, including 2- and 4-channel versions with analog waveform capabilities plus 2- and 4-channel versions which offer a combination of analog waveform and digital pattern generation capabilities. All models have a bandwidth of 125 MHz, maximum sample rate of 1 GSps, long memory of 2 Mpts/ch and 16-bit resolution.
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 customised to show only the windows that are of most interest to the user.
ArbStudio provides both true arbitrary and direct digital synthesis (DDS) modes and allows the user to choose which mode is needed for their waveforms. For added flexibility, ArbStudio channels can be set to any mode independently of each other.
