The Personal Audio Assistant 3 (PAA-3) RTA is a great hand held RTA for a number of common tasks with system tuning and OEM integration tasks.

This is a menu driven RTA that also has a polarity check, signal generator, and SPL meter. The XLR plugs on the bottom provide input and output capabilities so you will need to build XLR to RCA or speaker wire adapters (which is a breeze). Comes with a USB cable, carrying case, and wall charger.

Microphone is built in to the unit and “flips out”.
