59 -- FREQUENCY STANDARD SOL F29651-95-R0029. Due 110195. Contact Michael Freelander, 505/475-5297/Contracting Officer, Sharon L Gault, 505/475-5293. Rubidium frequency source must be physically and electrically identical to the Efratom Time and Frequency Products Inc. (ETFPI) Modular Frequency Standard, MFS-289 (four each). The MFS-289 consists of the following ETFPI components: Power Supply Assembly, model MPS, Part Number 808-460-5, module A4, Rubidium Oscillator, model MRK-L, part number 101656-001, module A3; frequency converter, 10.23 MHz, model MFC, part number 103422-020, module A6; Modular Buffer Assembly, 5 MHz sine, model MBF, part number 808-430-2302, module A7; Modular Battery Unit, 1 our model MBF, part number 808-500-2, module A9; and Wired Rack Assembly, consisting of 19'' rack, internal connectors and wiring, part number 103671. The MFS-289 must meet the following electrical sine outputs: four 5 MHz 1.0 Vrms into 50 ohms (internally adjustable 0.5 to 1.5 Vrms) at the MBF assembly (rear of system); four 10.23 MHz into 50 ohms, available on front panel of the MFC module (rear of system); and one 5 MHz and one 10 MHz output are available at the front panel of the system on the rubidium oscillator. The 10.23 MHz output signals available from the MRK, MBF and MFC modules are from BNC connectors, which mate with BNC-type connectors (male). Power requirements: Operate from 115 Vac at 60 Hz and +22.5 to +32 Vdc power, also operated from 100, 220 or 240 Vac at 47 to 400 Hz, but the ac input voltage selector PC board must be changed to the corresponding configuration of the selected ac voltage level. Based on the information available at this time and in accordance with 10 USC 2304(c)(1) as implemented by FAR 6.302-1, the Government considers the items specified as a sole source from Efratom Time and Frequency Products Inc, Irvine CA and proposes to negotiate a contract with that firm on that basis.
