They claimed BETA 1.0 was a "Stand-Alone Device"

From there it only got smaller and smaller - Power Source was designed the "Square Wave" - Your wrong about the Stand-Alone, they haven't came out and said the BETA 2.0 was but how would it not be being a BETA 2.0 and BETA 1.0 was

June 2016-Cannabix Scientists and Dr. Rick Yost at the University of Florida developed a standalone desktop-sized “Beta 1.0” FAIMS based device with a proprietary configurable high voltage power supply which operated with conventional power sources.

And if you read this one, there will be no Trials and the Scientific Testing will do, here you read the quote and point out Trials being done - controlled scientific testing protocol

The Beta 2.0 prototype has provided excellent sensitivity in lab testing and will be utilized to conduct scientific studies with live marijuana users (smokers and edible consumers) to test the device for its accuracy and sensitivity using a controlled scientific testing protocol. The results of the scientific test will be used to prepare submissions for approval of the Cannabix Marijuana Breathalyzer as a court-approved device by the Minister of Justice in Canada and the National Highway Traffic Safety Administration (NHTSA) in the United States. In addition, law enforcement officials and regulators for the Minister of Justice and the NHTSA will be consulted regarding additional features, roadside protocol, ease of use, and to define a final housing design for a finished product.
