Epoch of Reionization data analysis requires unprecedented levels of accuracy
in radio interferometer pipelines. We have developed an imaging power spectrum
analysis pipe to meet these requirements and generate robust 21 cm EoR
measurements. In this work, we build a signal path framework to mathematically
describe our analysis techniques, focusing on recent improvements such as
calibration. We trace the signal path through each step in the analysis, from
data reduction in the FHD package to power spectrum generation in the
$varepsilon$ppsilon package. We present our key data analysis products in
detail to facilitate understanding of the prominent systematics in image-based
power spectrum analyses. As a verification to our analysis, we also highlight
an end-to-end analysis simulation to demonstrate signal preservation and lack
of signal loss. This careful treatment ensures that the
FHD/$varepsilon$ppsilon power spectrum pipeline can reduce radio
interferometric data to produce credible 21 cm EoR measurements.
