The LSProbe 1.2 Field Probe is a high speed, high accuracy and high dynamic range electric-ﬁeld probe.
Its standard frequency range of 10 kHz – 8.2 GHz.
Best-in-class compensation of linearity, frequency and temperature guarantees accurate measurements from less than 0.1 to at least 1,000 V/m.
A dynamic range of 100 dB is achieved for many frequencies, enabling ﬁeld measurements at more than 10,000 V/m.
Customized high ﬁeld-strength „X“-variants, supporting up to 30,000 V/m and a damage level of 100,000 V/m, are available upon request.
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.
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 Software (TCP Server and GUI).
