A high resolution 16k spectrum
Taken during a demo at Kozloduy September 2016
Pulse generator at 16K, 8K, 4K, 2K and below factors
A set of pre-purchase evaluation spectra taken by a customer
Demo spectrum taken at customers
Taken at a demo at the Sofia reactor with a really old detector
Taken at a demo at the Sofia reactor with a very good detector

Taken using a customers ortec detector. The detector resolution in its prime has been measured by the manufacturer as:
at 1332.5 keV - 1.86 keV FWHM (1.85 FWTM/FWHM),
at 122 keV - 0.82 keV FWHM.

netMCA-3 results:
at 1332.5 keV - 1.70 keV FWHM (1.84 FWTM/FWHM),
at 122 keV - 0.78 keV FWHM.

A plug-and-play demo using a Canberra 50% detector. The detector resolution has been measured by the manufacturer as:
at 1332.5 keV - 1.85 keV FWHM, 3.41 FWTM at 122 keV - 0.88 keV FWHM.

netMCA-3 results:
at 1332.5 keV - 1.75 keV FWHM, 3.26 FWTM at 59.5 keV - 0.755 keV FWHM (no 57Co source was at hand so we used 241Am).

This is a spectrum taken with a pulse generator.
The same pulse output - somewhat below 1V peak - was acquired at conversion factors of 16384, 8192, 4096 and 2048 into the
same 16k spectrum at a 4 uS filtering equivalent.

Below is a series of screenshots of the fitting results of the peaks at 16k, 8k and 4k resolutions in linear and logarithmic Y representation; the spectrum was calibrated prior to each fitting so that the centroid of the fitted peak would be at 1332.5 keV.

This spectrum was taken at a demo session at customers with a 20+ years old 25% N-type detector - which was clearly still in good shape.
The people at that lab were impressed by the fact it took practically no warmup to get resolutions they had not seen using their analog
equipment (which was top-model NIM in the analog shaping days)

This spectrum was taken at a demo session at the reactor in Sofia with an old detector which has seen better days, but still worked OK.
