66 -- LOW NOISE SWITCH SOL F3366099Q7503 DUE 022699 POC Jim Hood, Contract Specialist, 740-788-5046 or Glenna Pound, Contracting Officer, 740-788-5043 AFMETCAL Det 1 intends to award a purchase order under Simplified Acquisition Procedures for the purchase of LOW NOISE SWITCHES.This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in the Federal Acquisition Regulation (FAR) Subpart 12.6 and 13.5 as supplemented with additional information included in this notice. This announcement constitutes the only solicitation, proposals are requested, and a written solicitation will not be issued. This solicitation, F33660-99-Q7503, is a request for a price quotation for 10ea LOW NOISE SWITCHES as described in the following: SCOPE : This Solicitation incorporates provisions and clauses in effect through the Federal Acquisition Circular 97-10 and Defense Circular 91-13. FAR clauses 52.212-4 and 52.212-5 apply to this acquisition. This purchase description identifies performance requirements for a programmable, IEEE-488.2-1992 Interface Bus compatible low thermal switch. It shall be used to intercompare saturated standard cells and solid state voltage references both in a manual mode or via remote control. COMPONENT : Listed in this purchase description are the Air Force minimum (but, not limited to ) functional requirements which are to be satisfied. Proposals offering an item that meets or exceeds the requirements of this purchase description will be evaluated for acceptability. COMPATIBILITY : This item must be compatible with equipment currently in use by the Air Force in the Direct Voltage measurement area. Items such as the Keithley 182 nanovoltmeter, the HP 200/300 series and Vectra series instrument controllers connected to a Shared Resource Managed(SRM) network. This compatibility should require little or no changes to existing SRM programs, when installed into the measurement system. ELECTRICAL SPECIFICATIONS : SWITCH INPUTS : Shall be provided to accommodate at least 16 two-terminal inputs. Input Connectors : Six-foot (182.88-cm) cables rear panel mounted. Untinned solid copper wire in groups of two pairs. A total of eight input cables(4 conductor or 2 pair each) will be required.SWITCH OUTPUTS : Four output lines: Two separate lines to accommodate positive inputs and two separate lines to accommodate common inputs. Output Connectors : Rear panel mounted low thermal binding post; tellurium copper. SWITCHING DESIGN : Shall be such to compare standard cells and solid state references using the NIST cell measurement technique. The design shall provide two relays connected to each input positive terminal and two relays connected to each input common terminal. This will accommodate switching polarities and reversing electrical position (left-right) of the input channels while providing short circuit protection to the test items.RELAYS : Latching type, requiring less than 15 milliseconds to actuate. Relays must be capable of remaining latched in the last chosen position when power to the unit is removed. Actuation Power : 0.5 Amp at 24 VDC maximum. Resistance : Less than 50 milliohms.Cycle Life : Greater than 10 million cycles. Replacement : Relays must be such that they can be easily removed from the circuit board for replacement.Thermoelectric Potentials : 100 nanovolts maximum. Error Contribution : Standard deviation less than 30 nanovolts when the NIST 4 x 4 cell design is run with all inputs shorted.SCANNER CONTROL : Shall operate both manually (front panel push-button) and remotely (IEEE-488.2-1992 ). Front Panel Control : Shall be push-button and designed such that the operator must press two buttons SIMULTANEOUSLY to close a relay. Remote Control : The instrument shall conform to the IEEE-488.2-1992 GPIB standard with five bit address selection. The instrument shall be fully operational from a remote instrument controller. It must have Talker and Listener capability. Logic Circuit Delay : 0.2 seconds maximum between successive relay actuations. Remote Lock : This item shall be capable of local lockout, which means front panel controls will be disabled to prevent tampering by external sources.. This function will be accomplished by means of an internal DIP switch. CELL PROTECTION : Protection must be provided to prevent a standard cell or solid state reference from being shorted due to scanner failure or operator error. Circuitry must provide for only one relay closing at a time and preventing any relay on an output line from being closed unless all other relays on that line are open. This capability must be extendible when linked together with similar scanners in a larger operating system. FRONT PANEL INDICATORS : LED indicators must be present on the front panel to indicate which output "HI" switches are closed. REMOTE/LOCAL indicators must also be present and operational.REPEATABILITY : With inputs shorted, switches shall repeat to +/- 50 nanovolts. GENERAL SPECIFICATIONS : POWER : 115 VAC +/- 10%, 60 Hz +/- 3%, 20 W maximum. Power Cord : The item shall be supplied with one assembled power cord, 3 (91.44 cm) to 6 feet(182.88 cm) in length. DIMENSIONS : No larger than 6.0 inches(15.24 cm) height, 20 inches(50.8 cm) depth, and capable of fitting into a standard 19 inch(48.26 cm) rack. WEIGHT : 30 lbs.(13.61kg) maximum. RACK MOUNTING : The unit shall be provided with all necessary accessories to enable rack mounting in a standard 19 inch rack. ENVIRONMENTAL: Operating Temperature Range: The unit shall perform to full specifications at 22.8 degrees C +/-3.3 degrees C. Operating Humidity Range: The unit shall perform to full specifications from 20 to 50 % RH. Storage Temperature: -20 degrees C to +60 degrees C. Storage Humidity: 15 to 80% RH. FUSE WIRING REQUIREMENTS : Connections to the extractor post-type fuse holders shall be such that the load is connected to the fuse terminal which terminates in the removable cap assembly.
