Weapon Signature Nullifiers and Amplifiers are Ultra Rare consoles available for requisition through the Fleet Embassy. They modify player's skill points like a standard Science Console, but include two other differences. They either increase or decrease threat and have one of the following effects: Plasma Explosion, Hull Restoration, or Shield Restoration.
Embassy Diplomatic Facilities Facilities Tier I is required to purchase the Mk X consoles.
Embassy Diplomatic Facilities Facilities Tier II is required to purchase the Mk XI consoles.
Embassy Diplomatic Facilities Facilities Tier III is required to purchase the Mk XII consoles.
As with all Fleet Holdings, you can get yourself invited to a different fleet's Embassy that is already upgraded to Tier III if your own fleet is lacking that particular upgrade.
These consoles boost the corresponding skill by the same amount as a normal science console of the same Mk level and quality, and so are flatly better than the standard science consoles:

Types
Plasma-Generating Weapon Signature Nullifiers and Amplifiers
Plasma-Generating Weapon Signature Nullifiers and Amplifiers add a chance to deliver a Plasma Damage effect on your energy weapon attacks. Energy weapons will receive a 2.5% chance to deliver a Plasma explosion effect. When using multiple Plasma Explosion consoles, the proc chances are not combined; using two consoles will mean an energy weapon will have two separate 2.5% chances to proc, not a single 5% chance.
Hull-Repairing Weapon Signature Nullifiers and Amplifiers
Hull-Repairing Weapon Signature Nullifiers and Amplifiers have a chance to trigger a hull heal whenever your ship is damaged. They have a 2.5% chance to perform an immediate hull repair when receiving damage. The magnitude of the hull heal scales with hull restoration and any other sources that boost hull healing capabilities. Upgrading each console also increases the amount healed.
Shield-Repairing Weapon Signature Nullifiers and Amplifiers
Shield-Repairing Weapon Signature Nullifiers and Amplifiers have a chance to trigger a shield heal whenever your ship is damaged. They have a 2.5% chance to apply an immediate shield regeneration when receiving damage. The magnitude of the shield heal scales with shield restoration and any other sources that boost shield healing capabilities. Upgrading each console also increases the amount healed.
These items originally had different names, carrying the name of a standard science console and then two modifiers: [Pla] for Plasma Infused, [HuH] for Hull Restoration, and [ShH] for Shield Restoration, and then [+Th] or [-Th] to indicate their threat modifier. Thus, a [Console - Science - Graviton Generator MK XII [-Th] [Pla]] became [Console - Science - Plasma-Generating Weapon Signature Nullifier MK XII [Grav]]. With the skill system change, the modifiers [Emit], [PrtG], and [Sen] became [ShHeal], [EPG], and [Per] respectively, with [Stealth] remaining the same, while [Inert] and [Grav] were rolled into [CtrlX], and [Ins] and [Flow] were rolled into [DrainX].
The Plasma-Generating consoles have been nerfed multiple times:
Prior to the February 26th, 2015 patch, their damage was considered Plasma Directed Energy Weapon damage and Plasma Exotic Damage, and thus were boosted by a variety of items, including themselves.
