66 -- 10V DC REFERENCE STANDARD SYSTEM SOL N00244-97-R-0031 DUE 062597 POC Gretchen Yeh, Contract Specialist (562) 626-7365; Dorothy Rodgers, Contracting Officer This is a request for information (RFI) to determine whether a suitable instrument exists that will meet requirements. Reference will be used to maintain the laboratory voltage standard. Individual 10V reference modules can be removed from system and transported between std labs for inter-comparison and voltage traceability. Each module will utilize patented conditioning circuits that reset the zener voltage at power on w/out the use of permanent battery backup normally associated with maintaining zener oven temperature during transportation. References that have been off power, even in envoronmentally adverse transport conditions, are to be returned to original value within 6-8 hrs of power restoration. The system will be module based and will have 4 EA 10V DC ref modules. Each module will have 2 outputs of 10V and 1V or 1.018V (selectable). Each system will include a switching scanner module and PC compatible control and analysis software. Scanner module will have ability to scan up to 16 channels. Each scanned channel will be compared with the avg value for those ref modules with the average selected. Scanner will measure and display individual ref deviations from the avg. Ref modules will have the following specs: 10V 1V/1.018V Time stability: <1ppm/yr <2ppm/yr Temperature stability: 0.05ppm/?C 0.2ppm/?C Noise (typical): 0.025ppm RMS 0.05ppm RMS Operating Temp range: 10 -- 35?C Storage temp range: -20 -- 45?C Isolation to ground: 10GW/100pF Isolation to ground: 20GW/3pF Dimensions: 115mm high, 75mm wide, 266mm deep (fits in 3U high EuroRack) Weight: <1.4Kg w/batteries Software: PC s/w will be available with the unit that will perform the following functions: maintain history; monitor ref deviations from the avg; recommend which units, if any, should be removed from the avg; recompute avg after ref contribution changes; maintain actual data value; perform regression and trand analysis; calculate new values from newly certified values or est values; Microsoft Excel data file format, Lotus compatible; and monitor records ref cell oven temperature. This is a request for information. Marketing literature and documentation should be submitted to the above address. The Government will not pay for any information submitted in response to this RFI. No solicitation document exists. (0136)
