NOAA Wallops Command & Data Acquisition Station Procurement of Radio Frequency Survey Systems

1. Introduction/Background:

The National Oceanic and Atmospheric Administration (NOAA) Office of Satellite and Product Operations (OSPO) is an organizational component of the National Environmental Satellite, Data and Information Service (NESDIS). The OSPO has operational responsibility for the Satellite Operations Control Center (SOCC) at Suitland, MD and the Command and Data Acquisition Stations (CDAS) at Wallops, VA and Fairbanks, AK to command and control the satellites, to track the satellites, and to acquire their data. The OSPO also manages and directs the operation of the central ground facilities which ingest, process, and distribute environmental satellite data and derived products, to domestic and foreign users.

The presence of high power Radio Frequency (RF) energy within Wallops CDAS antenna systems necessitates a biannual RF Safety Survey to be performed to detect potentially harmful RF leaks. This RF Safety Survey is performed on all Wallops CDAS transmit-capable antennas using a RF Survey System consisting of an RF Survey Meter and associated E-Field probe.

2. Scope of Work

The purpose of this acquisition is to procure two RF Survey Systems that meet the specifications outlined in paragraph three of this SON.

3. Specifications:

The specifications are solicited as a "Brand Name or Equal". Offers that are determined a non Brand Name substitute must fully meet the salient characteristics listed in the solicitation and the offer must include the substitute manufacturer specifications for evaluation.

NOAA Wallops CDAS requires RF Survey Systems, consisting of an RF Survey Meter and associated E-Field probe that meets the below requirements, at a minimum. The complete system requires both meter and probe. Requirements include:

Quantity (2) Narda Safety Test Solutions Radio Frequency Survey Meter Model# NBM- 550: Wallops requires this survey meter to replace failed and outdated meters currently in use, the Narda STS Model 8718B Survey Meter. The survey meter must be 1) in new OEM condition, and 2) a portable, handheld meter with an LCD display, controls for configuring the meter, and a physical and electrical connection point for the RF detecting probe, which is detailed below. The new survey meter must also meet the following specifications:

• Measurement units: V/m, mW/cm2 , W/m2

• Sensitivity:~ 1 µW/cm2

• Measurement Types: Real Time, Maximum, Average

• Battery/Power: battery-powered, rechargeable, ~20 hours operation per charge r

• Memory Storage: 2'.: 1000 readings

• Capable of accessing E-Field probe calibration factors

• Must be compatible with E-Field probe listed below

Quantity (2) Narda Safety Test Solutions E-Field Probe Model# EF1891: The E-Field Probe is required, along with the above survey meter to complete the RF Survey System. The probe shall contain RF sensing diodes or other component capable of detecting RF energy, a protective shell for the RF sensing elements, and an electrical and physical connection point for the RF Survey Meter, as described above. The E-Field Probe must in new condition and meet the following specifications:

• Isotropic Measurement Field

• Frequency Range: 10 MHz - 18 GHz

• Amplitude Measurement Range: 2'.: 1 µW/cm2 to 200 mW/cm2

• Linearity: +/- 3 dB from 10 MHz to 18 GHz

• Capable of storing probe calibration factors via EEPROM

• Must be compatible with RF Survey Meter listed above

4. Best Value Evaluation:

Offers shall be evaluated on an individual basis in accordance with the evaluation criteria outlined in the RFQ only. Award will be made to the responsible offeror that meets the best value to the Government. The offer must meet 1) Technical Specifications Acceptability, 2)

Delivery must meet the Government's need and 3) Price. Offers that meet or exceed these factors will be selected on a Lowest Price Technically Acceptable basis.

5. Delivery:

The delivery will 30 days from the date of award.

6. Security Requirements:

No contractor access to facilities or equipment is required under this requirement. Equipment will be delivered only. Authorized in-house personnel will install and configure the equipment in accordance with the FIS MA system's configuration management procedures.
