- Description
- The U. S. Department of Commerce, National Institute of Standards and Technology (NIST) has a requirement for 5 RF/CW Power Meters and 10 Power Sensors for CFGS Power Detection. These sensors and meters will be used to calibrate the input and reflected power for our antenna calibrations. There will be 5 sets of forward/reverse measurements taken (i.e. one pair per meter). The rear panel monitor ports will be used to interface with our amplifiers to allow direct shutdown of the amplifiers to prevent over-drive. These sensors will generate information used to calibrate delivered power to a calibration quality device. Low uncertainty, high degree of linearity and high RF performance over a wide bandwidth and power ranges are required. It is essential that the power meters and sensors meet the following technical specifications: 1) A quantity of 5 - dual-channel RF/CW POWER METERS. a) IEEE-488 computer interface connection. b) -70 to +20 dBm power sensing linearity must be maintained throughout the entire -70 to +20 dBm range. c) Full AGILENT 438/437 code compatibility/emulation - especially these five characteristics: (i) Code compatibility must be able to be programmed in power-up mode. (ii) Offset-on/Offset-off. (iii) Unit must maintain code compatibility with changes in sensors. (iv) Dwell time. (v) Measurement averaging. d) Emulation must be maintained through power cycle (ON-OFF-ON) and sensor change. e) Power meter must have a port to calibrate sensors - (and appropriate adaptors for sensor connectors) - calibration must be traceable to NIST. f) All sensors must be usable on all power meter channels. g) GPIB & remote setting of frequency. If a frequency selection is sent to the power meter - adjustments for correcting the reading of the sensor must be made at the power meter. h) Sensors must have frequency calibration factors in the sensor heads and calibration settings on the meters must be controllable over GPIB with a frequency selection command to the meter/sensors. The sensors must be able to identify itself by serial number when requested. i) Two monitoring channels per meter - one for each RF detection channel. 0 to 5 volts that is linear with RF detected by the sensor. Scale factor is user programmable - scale factor programming remains in memory through instrument preset and power-down-power-up cycle. BNC connector. Rear panel output. j) Zeroing feature - allows user to set the RF zero power setting as a reference point-zeroing of each channel must be independent. k) Labview drivers available for meters that perform multi-data point/channel measurement and averaging. l) Include a programmable calibration for external adaptors - meter and sensor can be calibrated to include a frequency selective calibration for adaptor/attenuator losses. 2) POWER SENSORS - 10 channels of power sensing - no external adaptors to get to the connector interface desired (additional adaptors increase VSWR, add loss and increase uncertainty in the RF measurement). a) 2 channels: 10 MHz - 6 GHz - Precision N male connectors-linearity 1.8% maximum - VSWR (0.1-2 GHz: 1.12),(0.01-6GHz : 1.22) b) 4 channels: 10 MHz - 18 GHz - Precision N male Connectors-linearity 1.8% maximum - VSWR (0.1-2 GHz: 1.12),(0.01-18GHz : 1.25) c) 2 channels: 10 MHz - 26.5 GHz - 2.92 mm K male Connectors-linearity (0.01-18GHz - 1.8%),(18-26.5GHz-2.5%) - VSWR (0.1-2 GHz: 1.12),(2-26.5GHz : 1.35) d) 2 channels: 10 MHz - 40 GHz - 2.92 mm K male Connectors-linearity (0.01-18GHz - 1.8%),(18-40GHz-2.5%) - VSWR (0.1-2 GHz: 1.12),(2-26.5GHz : 1.35),(26.5 GHz - 40 GHz: 1.5) e) 3 meter cables to interconnect the sensor and meters for all cables. f) All sensors must be DC blocked through the RF port - DC voltage on the RF line must not affect detected RF power reading. - CRITICAL SPECIFCATION - the systems attached to the sensors may have residual DC charge build up and this must not affect measured RF power. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures (NTE $100K). The proposed procurement is non-restrictive, but small businesses will receive preference. Written quotes will be received up to the close of business on July 3, 2003. Quotations should list product specifications addressing the above list of requirements and will be tested on-site before award. Upon receipt of the award, delivery must be within eight weeks. Selection will be based upon technical merit and price. Any questions should be sent in writing to Kelly.Rima@noaa.gov. FAR Clauses in full text are available at http://www.ARNET.gov/far/. Agency level protest procedures can be found on web site http://oamweb.osec.doc.gov/CONOPS/#REFERENCE. Hard copy in full text available from office address and phone number listed in notice. Anticipated award date July 8, 2003.
