Perception.Pnrf

.NET parser for the PNRF binary measurement format (HBK Perception).

PNRF files (.pnrf) are produced by HBK Perception data acquisition software and contain high-speed analog waveforms, digital events, CAN/fieldbus data, and SPT harmonic analysis results.

Installation

dotnet add package Perception.Pnrf

Usage

using PerceptionPnrf;
using PerceptionPnrf.Models;

using var pnrf = new PnrfFile("measurement.pnrf");

foreach (var rec in pnrf.Recorders)
{
    Console.WriteLine($"Recorder: {rec.LogicalName}");
    foreach (var ch in rec.Channels.Where(c => c.Segments.Count > 0))
    {
        var seg = ch.Segments[0];
        Console.WriteLine($"  {ch.LogicalName}: {seg.SampleCount} samples, unit={ch.Units}");

        // High-performance read into caller-provided buffer (zero allocation)
        var buffer = new double[1000];
        ch.ReadSamples(segmentIndex: 0, offset: 0, buffer.AsSpan());
    }
}

See the Sample application for a comprehensive demonstration including:

  • Full and partial (windowed) reads
  • High-performance chunked reads with buffer reuse
  • MATD (sparse async) channels with ZOH interpolation
  • Event channels (MEWD bit extraction)
  • SPT (spectrum) channels
  • Multi-segment traversal

Status

The API surface mirrors the Python implementation (perception-pnrf on PyPI).

Specification

The full reverse-engineered format specification is available in the spec/ directory of the source repository.
