Salient Characteristics Statement US Army Electronic Proving Ground (USAEPG) Procurement

1. Introduction and Purpose

• This document outlines the salient characteristics for the procurement of E- Field monitoring equipment required by the US Army Electronic Proving Ground (USAEPG). The objective is to acquire high-precision Radiation Hazard (RADHAZ) measurement systems capable of accurately assessing modern, fast-pulsing waveforms found in advanced radar and electronic warfare environments.

2. Additional Requirement:

• This requirement is solicited as a Brand Name or Equal.

3. Equipment Requirements

The following equipment configuration (or technical equivalent) is required:

• Narda Fieldman E-Field Monitor (Quantity: 12)

• EFD-1891 Fast Acting Probe (Quantity: 12)

• EFD-5091 True RMS Probe (Quantity: 12)

4. Technical Specifications and Performance Criteria

• Fieldman E-Field Monitor (Main Control Unit) The monitor must serve as the central processing unit for data visualization and probe management with the following minimum specifications:

• Form Factor: Ruggedized handheld unit.

• Dimensions: Maximum 315 mm x 95 mm x 55 mm (excluding probe).

• Weight: Maximum 700 g (including battery).

• Display: Minimum 5-inch sunlight-readable color TFT-LCD (1280 x 720 HD resolution).

• Power System: Replaceable Li-Ion rechargeable battery providing at least 15 hours of nominal operation.

• Charging: Support for USB-C Power Delivery (PD).

• Interface: Digital probe interface that eliminates the need for separate meter calibration.

• Connectivity: USB-C, Gigabit Ethernet, and Optical interfaces.

• Environmental Protection: Ingress Protection rating of IP54 or better.

• Integrated Sensors: Must include internal sensors for temperature, humidity, and air pressure for automated environmental logging.

5. EFD-1891 Fast Acting Probe

The probe must be optimized for fast-pulsing waveform detection with the following characteristics:

• Frequency Range: 2 MHz to 18 GHz.

• Measurement Range: 0.6 V/m to 1000 V/m.

• Sensor Type: Diode-based for fast response times.

• Dynamic Range: Minimum 60 dB.

• Architecture: Digital-at-the-head signal conversion to prevent analog signal degradation.

6. EFD-5091 True RMS Probe The probe must provide accurate power measurements for complex waveforms:

• Frequency Range: 300 MHz to 50 GHz.

• Measurement Range: 8 V/m to 614 V/m.

• Sensor Type: Thermocouple-based (True RMS).

• Requirement: Must provide mathematically accurate True RMS values for overlapping pulsed signals and high peak-to-average power ratios (PAPR).

• Architecture: Digital-at-the-head signal conversion.

7. Critical Mission Requirements To meet the specific testing needs of USAEPG, the proposed system must satisfy the following:

• Pulse Handling: The system must accurately integrate the power of complex, fast-pulsed radar waveforms that typically saturate standard diode-only probes.

• Signal Integrity: Probes must digitize signals internally to prevent interference and maintain integrity over high-speed analysis.

• Calibration: Probes must be independently calibrated with the calibration data stored digitally within the probe head, allowing for "plug-and-play" operation with any compatible monitor unit.
