Isotropic Broadband Electric Field Probe PI-03P 100MHz-18GHz

Probe PI-03P

 Isotropic Pulsed Electric Field Probe PI-03P 100 MHz-18 GHz:


100 MHz-18 GHz, 70-1400 V/m. Broadband isotropic electric field probe PI-03P measures the pulsed RF field produced by the microwave radars. It has fast sampling capability measuring the field strength of RF bursts (pulses) as short as 1 us (one microsecond). It operates in the frequency range 100 MHz – 18 GHz, covering the test requirements of MIL STD-461 and automotive EMC GM and Ford specifications.

Calibration Details:  

– Keep unit calibrated. We recommend calibration once a year in our UK NPL traceable EMC Test Lab.

All calibration tests are perormed in EMC Test Design, LLC test lab and are based on transferable field measuring probes and antennas traceable to United Kingdom National Physical Laboratory (UK NPL).

Probe PI-03P

1) Meter/Probe Linearity 70-1400 V/m @942.5 MHz,

2) Probe Frequency Correction Factors at 25 specified frequencies in the frequency range 100 MHz-18 GHz.

3) Probe Rotational Isotropicity @ 100 and 1900 MHz (@100 V/m).

 – To convert the electric field strength E (V/m) into power density S (uW/cm2) use formula: S=E2/3.77. To calculate the value of the magnetic field H (far field region) use the relationship: E/H=377 Ohm.
