CmDsOfdmHistogram — downstream OFDM histogram

Parser for downstream OFDM histogram captures (power-level distributions).

Module location src/pypnm/pnm/parser/CmDsOfdmHistogram.py

Inputs

• DOCSIS histogram payload captured via the histogram endpoint.

Outputs

CmDsOfdmHistogramModel exposes:

• bins: [start_dbmv, end_dbmv, count] tuples for each histogram bucket.
• header: timestamps, total codewords, and bin width.

Usage

from pathlib import Path
from pypnm.pnm.parser.CmDsOfdmHistogram import CmDsOfdmHistogram

payload = Path("histogram.bin").read_bytes()
hist = CmDsOfdmHistogram(payload)

bins = hist.get_bins()
