Data

 


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 18GHz.

The Field Probe’s six-monopole antenna design ensures isotropic operation at all frequencies.

LSProbe 2.0 employs fine-grained compensation of linearity, frequency and temperature, guaranteeing accurate measurements from less than 1V/m to at least 1 kV/m.

A dynamic range of 60 dB is achieved for all frequencies.

LSProbe 2.0 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 EN300 328 and EN301 893.

Laser-powered operation eliminates battery recharging and replacement. Extensive in-house calibration data are provided with each field probe and is handled automatically by the LSProbe TCP Server Software.

LSProbe 2.0 is backward compatible with LSProbe 1.2, supporting the same SCPI commands. Consequently, it inherits third-party EMC-software support for R&S EMC32, R&S ELEKTRA, emcware, BAT-EMC, Tepto, Tile, Win6000, Compliance5 and Radimation.
