The NI PXI-6552 is a 100 MHz digital waveform generator and analyzer delivering per-cycle, per-channel bidirectional control across 20 channels for precise digital electronics validation and testing. Programmable voltage levels span -2.0 V to 5.5 V in 10 mV increments, with configurable onboard memory up to 64 Mb/channel. The instrument executes single-waveform and scripted generation modes, supporting complex test sequences with real-time hardware comparison of acquired response data.
