66 -- VHF FIELD STRENGTH METER SOL NWWR4000000047 DUE 090100 POC Patsy Ybarra (816) 426-6823, x230 The National Weather Service has a requirement for five (5) VHF Field Strength Meters. Some of the specifications are as follows: FREQUENCY RANGE -- 45 MHz-225 MHz continuous; RF INPUT IMPEDANCE/VSWR -- 50 ohms/1.2:1, 100 uV full scale and greater; 50 ohms/1.5:1 10, uV full scale; BNC Connector; VOLTAGE MEASUREMENT -- 1 uV to 10Vrms in seven switch-selected ranges; METERING -- 4-1/2 inch meter, mirror-backed scale, Indication Modes LIN (linear) and Log (with receiver dc feedback), switch selected; Scales LIN Scales: 1-10 logarithmic and 0-20 dB linear; LOG Scale: -20 to +40 dB linear (60 dB range) Battery voltage/external supply voltage scale; METERING DETECTORS -- Average responding and Peak responding (for television sync pulse), switch selected; RECEIVER BANDWIDTHS -- AM/FM, 190 kHz at -3 dB, and TV, 450 kHz at -3 dB, switch selected; ABSOLUTE ACCURACY -- Voltage: + or -- 1.5 dB (LIN), + or -- 2.0 dB (LOG), for voltage > 1.5uV (AM/FM) or > 3, uV (TV), Field Strength:+ or -- 3.0 dB (LIN), + or -- 3.5 dB (LOG); for field strengths > 1.8, uV/M (AM/FM) or >9.1 uV/M (AM/FM) or >18.1, uV/M (TV) at 225 MHz; using the ANT-71 Antenna; RELATIVE ACCURACY + or -1 dB at one frequency, for voltage or field strength, LIN mode, for voltages > 10 uV, with Noie correction factors, etc. (Note: The RFQ will include additional specifications). Interested parties shall request a copy of RFQ NO. NWWR4000000047PY in writing. Copies may be requested via facsimile no. (816) 426-7530. Posted 07/20/00 (W-SN477017). (0202)
