Electric Field Probe Calibration

Methodology of calibrating the probe factor near field scanning.

Electric field probe calibration.

Calibration result of electric field probes using one port tem. The method describes equipment and facilities used to generate standard electric fields up to frequencies in the microwave range. The rf field probe is fiber optically coupled to the readout or pc interface to eliminate the possibility of cable interference. The rfms comprises an atomic rf field probe rfp connected by a ruggedized fiber optic patch cord to a portable mainframe control unit with a software interface for rf.

Hi6005 were obtained from the result of the refere. For standalone applications each tds time domain field probe is delivered with an 8 m rugged fiber optic cable attached directly to the probe. The standard calibration level is 20 v m but optionally e field probes can be calibrated up to 200 v m 100 khz up to 200 mhz and 100 v m 200 mhz up to 40 ghz. Data sheet emc test design isotropic broadband electric field probe probe pi 01 200 khz 3 ghz 0 2 600 v m pi 01c isotropic field probe 500mhz 2ghz 02ghz 600v m.

A highly accurate method of calibrating such probes is discussed. In order for isotropic e field electric field probes to measure the strength of electric fields accurately they must be calibrated very accurately. 2 for the h field probe the probe factor is defined as. Calibrations is iso iec 17025 accredited to calibrate e field probes in a maximum frequency range from 100 khz to 40 ghz.

We present a self calibrating si traceable broadband rydberg atom based radio frequency rf electric field probe the rydberg field probe or rfp and measurement instrument rydberg field measurement system or rfms. A small electric field probe is essential for measurements in a uniform field of an anechoic chamber. Ets lindgren s model h 491269 probe stand is designed for accurate and repeatable probe positioning when performing field uniformity calibration in accordance with 61000 4 3 and 61000 4 21 among other emc and military. Tds electric e field probes are miniaturized active optical electrical field probes for use in free space media εr 1.

For the e field probe the probe factor is defined as. Electric field probe pi 01c was designed for selective rf measurements. The calibration factors f p of two field probes fp2 080 and. What was forgotten is that the position of probe has a more impact on the accuracy and reliability of the measurement.

3 where e is the strength of the electrical field h is the strength of the magnetic field is the measured voltage. Data from each axis can be viewed individually or summed. Ets lindgren s hi 6023 electric field probe with field replaceable battery has a frequency response of 10 khz to 1 ghz br.
