E-FIELD NEAR-FIELD PROBES
SPEAG has pioneered the research and development of electromagnetic probes. All probes have been optimized by means of full-wave 3D simulations to achieve maximum spherical isotropy with avoidance of or compensation for any field distortion from mounting materials. Special techniques have been developed to minimize secondary modes of reception. Only the best low-loss materials are used, making the probes very rigid and compatible with almost any media. SPEAG has also pioneered the calibration techniques that enable the most precise measurement of electric, magnetic, dosimetric, and temperature quantities.
| FREE-SPACE – EL3D/EF3D |
Isotropic electric (E-) field probe for general near-field measurements. Different versions cover frequencies from 4 MHz up to 6 GHz. Sensors, small dipoles, are oriented in a Cartesian coordinate system that provides both field components as well as total field value with the highest precision. Frequency range: 4 MHz – 3 GHz (EL3DVx); 30 MHz – 6 GHz (EF3DV3) Dynamic range: 2 – >1000 V/m Tip diameter: 12.0 mm (EL3D) and 4.0 mm (EF3D) Scanning distance: ≥5 mm |
| UNIVERSAL – EU2D |
Universal E-field probe for dosimetric and general near-field measurements in air or liquids. Two optimally arranged dipoles, three measurements per point (rotated 120º) and advanced post-processing algorithms. Frequency range: 10 MHz – 10 GHz Dynamic range (air): >2 – >1000 V/m Tip diameter: 2 mm Scanning distance: ≥3 mm Detailed specifications: EU2DV3 |
| UNIVERSAL mmW – EUmmWVx |
Universal mm-Wave E-field probe for dosimetric and general near-field measurements in air or liquids. Two optimally arranged dipoles, three measurements per point (rotated 120º) and advanced post-processing algorithms. Frequency range: 750 MHz – 110 GHz Dynamic range: <50 – 10'000 V/m with PRE-10 (min <50 – 3'000 V/m) Tip diameter: 8 mm (internal sensor <1mm) Scanning distance: <2 mm Detailed specifications: EUmmWVx |
| TIME-DOMAIN – ETDS |
Miniaturized time-domain sensor (TDS) probes for frequency-selective E-field (E1TDS) measurements. TDS probes are available in rugged (standalone) and handheld (SNI) versions. Frequency range: 10 MHz – 6 GHz Dynamic range: 0.3 mV/m – 300 V/m Tip size: 4 × 4 mm2 Scanning distance: ≥1.5 mm |
| LF E&H-FIELD – MAGPy |
