FCC Form 422 attachment Item 4(F) — Particulars of operation — Modulation Signal Information rate: 1200 b/s + 20 b/s Information content: CW carrier, 9 bit preamble, 20 data and parity bits Modulation coding: Manchester bit encoding Maximum keying rate: 2400 baud Modulation type: Binary frequency shift keying with 3k + 0.6k Hz deviation Fixed length packet transmission duration is less than 27 mseconds per detection of each vehicle or pedestrian passage. Detection equipment design optimized for sparsely populated deployment. Item 4(G) — Particulars of operation — Description of necessary bandwidth 99 2.4 k baud keying rate: Mmayx = 2.4k. First null of sin x/x modulation response is +2.4k Hz Binary FSK modulation with +3k Hz + .6k Hz deviation: Dmax = 3.6K Hz Necessary bandwidth: Bp = 2M + 2D = 12k Hz Item 7 — Government contract supplemental information Project Name: iRembass — Improved Remote Battlefieid Sensor Contract Number: DAABO7—91—C—M360 Contract Agency: US Army — CECOM Ft. Monmouth, NJ 07703—5000 Contract Program Manager: Robert Foresta SFAE—IEW—EW Ft. Monmouth, NJ 07703—5000 tel: (908) 544—5883 Item 13 — Installed Equipment Martin Marietta is under contract to manutfacture 1300 transmitting sensors and packet repeaters under the current Government contract with expected options for production of additional units under future contract extensions. Related to the manufacturing task, some sensors may be required to be evaluated under field conditions to assess performance and provide qualification data. Field testing may also be performed to evaluate circuit modifications or design improvements made under the contract or related research and development programs. Nominally three, and no more than ten units will be deployed during any evaluation exercise.
