The Dusat aft-firing EMP emitter represented a specific type of electromagnetic pulse weapon. It was designed to be installed on the Joben T-85 speeder bikes manufactured by the Zebulon Dak Speeder Corporation. During an operation on the planet Lothal, the Jedi Kanan Jarrus deactivated the EMP emitter that was part of his T-85 speeder bike.
The Dusat aft-firing EMP emitter was initially brought to light in Star Wars Rebels: The Visual Guide. This reference work, authored by Adam Bray, was made available to the public in 2014. The appellations assigned to the Joben T-85 speeder bike and its associated parts serve as nods to Star Wars Legends personalities featured in Star Wars: Droids: The Adventures of R2-D2 and C-3PO. Specifically, the bike's name is derived from Thall Joben, the EMP emitter's name is from Jord Dusat, and the Moll K-19 power generator shares a name with Kea Moll.
