COMMERCE BUSINESS DAILY ISSUE OF NOVEMBER 16,1999 PSA#2476U.S. Dept. of Commerce, NOAA, WASC, Acquisition Management Division
WC3, 7600 Sand Point Way NE, Bin C15700, Seattle, WA 98115-0070 58 -- REQUEST FOR QUOTATIONS ISSUED FOR ZEPHYRUS SATELLITE UPLINK
EMWIN 9600 BAUD MODULATORS SOL WASC-0-378 DUE 112999 POC Randall Brown
(206) 526-6226/FAX (206) 526-6025 Request for quotations issued for
four (4) ea. Zephyrus Electronics. Ltd. or equal satellite uplink EMWIN
9600 baud modulators. Modulators are critical items to support the
rebroadcast of the EMWIN signal to PEACESAT (GOES-7). Modulators are
required to convert RS-232 data to information that can be passed
through the satellite utilizing minimum bandwith. These modulators will
consist of two separate modules, an asynchronous to synchronous
converter which pre-processes RS-232 data to be applied to the
modulator and a modulator to covnert the pre-processed data to V.35
encoded DFSK data for transmission through the satellite. These systems
will allow software compression at rates beyond 56K as needed. A total
of four satellite uplink EMWIN modulators are required, two units
operating at IF of 160.775 MHz and two units operating at IF of 132.775
MHz. Asynchronous to synchronous converter must accept RS-232 data at
9600 baud and convert it to synchronous TTL data to be applied to the
modulator; mount in a19" rack panel; include AC/DC power supply; and
meet or exceed 1.0 x 10(-6) bit error ratio (BER). Modulator must
accept synchronous data from the async/sync converter and convert it to
V.35 encoded DFSK data modulated onto a 72-74 MHz carrier which is
adjustable in .00125 Mhz steps; be assembled in a 19" rack cabinet;
include AC/DC power supply; meet or exceed 1.0 x 10(-6) bit error ratio
(BER); exhibit frequency stability at 72-74 MHz or better than 3ppm
between 10 degrees C and 50 degrees C; and deviate +1/-3.6Khz from
center frequency. Test and acceptance criteria: each unit shall be
tested for a period of 72 hours (30 days x 24 hours per day) prior to
delivery to ensure conformance to the above specifications; tests shall
be conducted at a facility local to the NWS Headquarters to allow
spot-checking for test accuracy by NWS personnel; and coordination for
earth station testing after NWS employees install units at various
uplink facilities. Provide price, published pricelist, availability,
Federal Tax ID number, and Dunn & Bradstreet DUNS number with quote.
Delivery to Honolulu, HI. State if under GSA contract or open market.
This is a simplified acquisition with an estimated value of less than
$100,000. Posted 11/12/99 (W-SN400400). (0316) Loren Data Corp. http://www.ld.com (SYN# 0170 19991116\58-0008.SOL)
