Arbitrary Waveform Generation
Arbitrary Waveform Package
An optional software tool for the design of analog ultrasonic waveforms using the Vantage NXT tri-level transceiver.
Leverages transceiver dynamic range, resolution, and linearity in combination with proprietary encoding algorithms for high fidelity AWG.
Performance approaching that of high bit-depth signal generators and linear amplifiers, achievable for high channel counts at a fraction of the price and power consumption.
Available through both a user-friendly GUI and API.
Available on new systems or as an upgrade on all Verasonics systems. It includes Extended Transmit and Arbitrary Waveform Capabilities.
Arbitrary Waveform GUI for Vantage NXT
Experimentally measured pseudo-random arbitrary ultrasonic waveform: 5-11 MHz Bandwidth
Benefits of Arbitrary Waveform Generation
Improved Axial and Contrast Resolution
Improved Penetration
Imaging in Aberrating Media
Increased Frame Rate and penetration depth
Vantage NXT Transceiver
Every Vantage NXT system supports user-programmability of the tri-level transmitter.
Transmit voltage waveforms are independently programmable for every channel.
Coded and arbitrary waveform lengths on the order of milliseconds (with Extended Transmit).
High fidelity waveform coding is enabled through:
- High timing resolution: 2 ns
- High dynamic range: Minimum pulse width of 4 ns
- Ultra-low harmonic distortion and high pulse-inversion symmetry
