Model V346

8-channel VME 32 MHz arbitrary waveform generator w/ complex modulation

Overview

Features:
  • 8 channels of independently programmable sine, sawtooth, triangle, and square/PWM/pulse, Gaussian noise, and arbitrary waveform generation
  • Clean, easy-to-program architecture for basic waveform generation
  • Channel-channel summing
  • Channel-channel synchronization allows generation of polyphase or synchronized waveforms within one module or across up to 16 modules in one crate; expandable to an unlimited number of channels
  • Selectable output frequency range of 0-32 MHz (functional past 40 MHz), with 0.015 Hz resolution to 0-250 KHz with 166 uHz resolution
  • DC coupled 50-ohm outputs to 10.24 volts peak-to-peak
  • Bandlimited Gaussian noise generation allows direct noise output and noise floor summing
  • Programmable offset allows wave+offset or direct DC DAC functionality
  • Programmable channel phase allows quadrature or polyphase waveforms
  • Programmable digital pulse/PWM outputs generate precision digital outputs for motion control or optical encoder simulation and can simulate transducers or quadrature encoders, or drive switchmode H-bridges with complex waveforms
  • Auxiliary connector provides waveform sync outputs and digital expansion
  • External TTL inputs can reset, update, or synchronize channels or initiate single-shot waveforms, for single boards or across multi-board systems
  • Includes built-in self-test (BIST) and channel test connector, allowing in-crate check of channel performance without removing field wiring
  • Any-to-any channel modulation: AM, FM, PM, and PWM
  • Noise modulation allows calibrated jitter
  • Control channels allow complex sequences of operations to be generated in real-time across multiple channels on one board or many
Description:

The V346 provides eight independent digitally synthesized waveform outputs, each programmable for frequency, amplitude, and phase.

Channel-channel modulation, summing, synchronization, and noise generation allow complex coordinated waveform generation within one module or across multiple modules. Hundreds or thousands of channels may be exactly synchronized through local electrical or remote fiberoptic links. Any output may be switched to a front-panel test connector, allowing in-crate calibration check without removing field cables.

The signal-processing capability of the V346 is sufficiently general that a wide range of complex functions can be easily programmed from the "first principles" of signal/systems theory. This includes quadrature signal generation, DSB/SSB of arbitrary waveforms, sweeps and chirps, QAM/constellation generation, frequency hopping, FSK generation, multichannel frequency tracking, and quantitative control of noise and jitter.

One or more V346 modules may also be used to simulate complex, high-channel-count processes, such as radar and sonar arrays, complex rotating machinery and structural systems, diesel/jet engine simulation, stationary and aircraft AC power systems, thyristor/IGBT phase control, and many others.

The T346, a compact stand-alone, non-VME, RS-232/Ethernet controlled version of the V346, is also available for embedded applications.

The V346 can be an ideal system replacement for the HP models 3314A, 3325A, 3325B, 3326A, 8111A, 8116A, 8165A, 8175A, and 8904A.
