LSProbe 2.0, 9 kHz – 26.5 GHz

The LSProbe 2.0 Field Probe is a next-generation, high speed, high accuracy and high dynamic range electric-field probe. Its frequency range is 9 kHz to 26.5 GHz. The Field Probe’s six-monopole antenna design ensures isotropic operation at all frequencies.
LSProbe 2.0 Field Probe employs fine-grained compensation of linearity, frequency and temperature, guaranteeing accurate measurements from less than 1 V/m to at least 1 kV/m. A dynamic range of 60 dB is achieved for all frequencies.

LSProbe 2.0 Field Probe contains a low-frequency and high-frequency detector for each of the six monopoles. The detectors can be operated continuously at 500 kSamples/s or in burst mode at 2 MS/s. This enables direct radar pulse measurements and accelerated, frequency sweep-based measurements.

A single axis, continuously sampling mode, operating at 2 MS/s, can be used for Equivalent Isotropically Radiated Power (EIRP) measurements of IoT products without antenna connectors in accordance with EN 300 328 and EN 301 893.
You can also read out the measurement data of all six axes simultaneously with a snap of your fingers.

Laser-powered operation eliminates battery recharging and replacement. Extensive factory calibration data are provided with each field probe and is handled automatically by the LUMILOOP Software (TCP Server and GUI).

LUMILOOP is an DAkkS certified Accredited Calibration Lab for E-Field Strengths. We deliver accredited calibrations up to 26.5 GHz and up to 600 V/m, ensuring reliable performance for demanding EMC, RF, and industrial applications.
