A prototype of the PIP-II linac front end called PIP-II Injector Test (PIP2IT) is being built to retire technical risks associated with acceleration at low energies. As of now, the Warm Front End - a 15 mA DC, 30-keV H- ion source, a 2 m-long Low Energy Beam Transport (LEBT) and a 2.1 MeV CW RFQ, followed by a 10 m Medium Energy Beam Transport (MEBT) - has been assembled and commissioned. One-plane beam phase portraits were recorded in the MEBT with an Allison scanner and analyzed in action-phase coordinates. This report describes the found beam distribution and presents the most important measurements performed with the scanner.
