Broad-spectrum warp field
A broad-spectrum warp field, also known as an inverse warp field, was a type of warp field created by specially-modified warp engines, used to keep a starship stationary in space. It was analogous to dropping the anchor for a starship. ()

In 2370, an alternate quantum reality-counterpart of Lieutenant Commander Data determined that, by piloting a shuttle into a quantum fissure and initiating such a warp field, Lieutenant Worf would be able to seal the fissure and return to his own universe, as he had been uncontrollably shifting to different realities as a result of an encounter with the fissure. ()

In 2376,  used such a warp field in an attempt to ride out a massive neutronic wavefront impacting its shields at a velocity of 200,000 kilometers per second. The warp core needed to be converted before the field could be generated. ()
