Ethernet-based waveform playback unit

Jon Lawson

The Highland Technology model P350 Wayback Machine is a compact Ethernet-based waveform playback unit designed specifically for aerospace simulation testing.

It provides eight analogue outputs that can be used independently or synchronously. In Playback mode, any P350 channel can store and play multi-gigabyte user waveform files, with flexible playback rates, summing, filtering, scaling/offset, and phase/timeshift provisions. Any channel can also operate in Wavetable mode, playing repetitive standard or arbitrary waveforms.

Two analogue inputs and two random noise generators are available for modulation or summing. Programming features allow accurate, glitch-free, low-jitter simulation of complex waveforms as might be generated by sensors on jet engines or other complex machines.
