Demo spectrum taken at customers
Pulse generator at 16K, 8K, 4K, 2K and below factors
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

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)

Here is what the 1332.5 keV 60Co peak looks like:

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 the reactor in Sofia with an old detector which has seen better days, but still worked OK.
