LSProbe 1.2, 9 kHz – 8.2 GHz

The LSProbe 1.2 Field Probe is a high speed, high accuracy and high dynamic range electric-field probe.
Its standard frequency range of 9 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 LUMILOOP Software (TCP Server and GUI).

Optional Upgrade CI-250+

CI-250+
CI-250+ with 19″ Rack Mount Kit

The CI-250+ is equipped with a 4.3″ touch screen and Ethernet interface. It runs the LUMILOOP TCP Server and a simplified GUI.

CI-250+ has an internal power supply. The fiber optic connection as well as triggering and synchronization options are unchanged compared to a classic CI-250.

Dimensions: width x height x depth = 200 x 88 x 150 mm (fits in 2 19″ height units, rack mount kit available)

The Computer Interface CI-250+ is an optional upgrade of the Computer Interface CI-250.
It can only be ordered combined with one of the following part no.: 1111, 1112, 1113, 1120, 2107-2109, 2117 – 2119
