The LSPM 2.1 from LUMILOOP is a Power Meter with a frequency range from 9 kHz to 26.5 GHz. This 3-channel laser-powered power sensor provides a channel isolation of more than 50 dB and employs robust sensory heads that can withstand more than 1000 V/m of electric field. It has a sampling rate of up to 2 Msamples/sec, allowing for high-resolution time-domain signal analysis, and can be synchronized with signal generators in order to realize high-resolution pulse analysis. This power meter has a dynamic range of 63 dB, an amplitude accuracy of 0.15 dB, a linearity error of 0.2 dB, temperature stability of better than 0.2 dB and a power resolution of 0.1 dB. It supports multi-device systems and Multiple LSPMs can be combined to obtain additional channels.

The LSPM 2.1 comes with fiber cable lengths of up to 1000 m, allowing remote operation without worrying about ground loops. It can be combined with CI-250+ computer interfaces, which are equipped with a 4.3” touchscreen and Ethernet interfaces. The CI-250+ displays RF power, field strength, laser status and more at a glance. It allows galvanically isolated RF power measurements, automated test setups, ISO 11452-4 BCI tests, and ISO 11452-9 portable transmitter tests. This power meter is available in an enclosure with 2.92 mm connectors and is suitable for ETSI EN 300 328 wideband transmission systems and ETSI EN 301 893 broadband radio measurements.
