The pulse-shape discriminator - Model 2160A - can be used to separate neutron and gamma particles, alphas and protons, electrons and alphas etc depending on the detector used. See individual data sheets for more details and specific features, as well as for the NIM power requirements if applicable.

To set the audio levels: Start with txctcsslevel in voter.conf set to 0. Set the txctcss and txtoctype options in voter.conf as necessary for your application. Send a 1kHz@3kHz on-channel, full-quieting, signal in to the repeater's receiver. Use Menu …

Keep in mind that all the audio in a Quantar (even analog) is digitized, so you never get to see what would be raw, analog discriminator audio. As a comparison, I looked at the receive side of a CDM mobile radio which is known to work well with MMDVM DMR and found the phase delay was very consistent, unlike the Quantar receive.

Motorola QUANTAR Compact Micro Controller – …

The QUANTAR ECM is unique. Our design allows the repeated audio to remain entirely within the repeater. Unlike other controllers that route the audio outside of the cabinet, our design leaves the audio alone. Since we do not interfere with the repeat audio path, the QUANTAR ECM will not affect the repeater's alignment settings.
Discriminator output - The RadioReference Wiki
https://wiki.radioreference.com/index.php/Discriminator_output
The Discriminator output from a scanner is the raw, unfiltered signal that a scanner produces before it is sent to the audio stage for output through the speaker -- also called the "baseband audio." This discriminator source is required for applications such as Trunker, T4Win, UniTrunker, and DSD.
