receives data from hf chirpsounder and spectrum monitor; 47-440 hz; single phase; 120 watts; provides means for rapidly assessing effects of REAL-Time hf propogation and spectrum occupancy measurements on specific assigned frequencies and radio circuit configurations; bands and assigned frequencies for up to 8 hf paths and presenting results in a series of crt displays for operator information and action
An item that contains circuitry which receives digital and analog drive signals from external equipment or from radio frequency electromagnetic waves. The data is then processed and applied to supporting equipment. Excludes processor, radar data and radio navigation data.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
Digital cpus, adp central processing units for computers. Represents only cpus that accept information represented by digital impulses. Specifically, a device capable of performing sequences of arithmetic and logic operations (a program) not only on data but also on the program which is contained in its internal memory (storage) without intervention of an operator.
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
