The name "tone-arm" says it all! If they are neutral, they would be called pick-up arms or similar.
May I make a suggestion! To eliminate cartridge set up variables, play a silent track, that is one containing no musical information, so no VTA adjustment, tracking force, or overhang comes into the equation. The groove contains nothing but inherent vinyl noise, plus any extraneous wear and tear. I use a test disk from Analogue Productions "The ultimate analogue test LP".
The output is turntable noise plus record noise. For analysis, I feed the microphone output from my pre-amplifier into the audio jack on my laptop, using the first free (home use only) analysis software I found on the web, WavePad by NCN Software.
Come to think of it, I have not seen a waterfall graph published for ages - about the time magazines stopped publishing useful stuff like speaker impedance curves.
