Electric-Field Sensor: LSProbe 2.0/ 1.2 10 Hz - 26.5 GHz

The Laser-Powered LSPM High‑Speed Power Meters are available as a triple, dual or single channel power meter. The Laser-Powered LSPM High‑Speed Power Meter combine high dynamic range and high resolution. It allows for high‑speed and high‑accuracy power measurements in the frequency range from 9 kHz to 26.5 GHz.

The main features of the Laser-Powered LSPM are:

• optical power and data transmission
• power head inside chamber
• no separate power supply
• reliable and stable connection
• 1.000 m fiber cable length

• high accuracy which is achieved based on an extensive in‑house calibration including frequency and linearity compensation and actively stabilized power sensor temperature
• high sampling rate of 2 MSamples/s which allows for high‑resolution time‑domain measurements
• quick and straightforward combination of the Laser-Powered LSPM Power Meter and the LSProbe 1.2 and LSProbe 2.0 E-Field Probe which allows for significant time‑savings when performing various EMC measurements, e.g., according to IEC 61000‑4‑3 and IEC 61000‑4‑21.

Available as LSPM 1.1 with a frequency range from 9 kHz to 8.2 GHz and as LSPM 2.1 with a frequency from 9 kHz to 26.5 GHz.

LSPM 1.0+/2.0+ Triple High-Speed Power Meters are three channel, high speed, high accuracy and high dynamic range RF Power Meters. Single and dual channel versions are available as well. Their frequency range is 9 kHz to 8.2 GHz for LSPM 1.0+ and 9 kHz to 26.5 GHz for LSPM 2.0+.

Compensation of linearity, frequency and actively controlled power sensor temperature guarantee accurate measurements. A dynamic range of 80 dB for LSPM 1.0+ and 72 dB for LSPM 2.0+ is achieved for many frequencies.

The LSPM 1.0+/2.0+ Power Meters’ high sampling rate allows for high resolution time-domain signal analysis. Power Meters can be synchronized with signal generators in order to realize high resolution pulse analysis.

LSPM 1.0+/2.0+ allow for RF power measurements, automated test setups, ISO 11452-4 BCI tests and ISO 11452-9 portable transmitter tests. LSPM 2.0+ is particularly well suited for ETSI EN 300 328 wide band transmission system tests and ETSI EN 301 893 broad band radio measurements.

ISO11451-5:2023 eliminates the need to calibrate the reverb. It defines real time closed-loop field strength
control, based on statistics from 8 E-field probes. Target field strength is defined by a cumulative distribution function (CDF).
Sounds complicated? LUMILOOP makes this super easy to operate and integrate!
LUMILOOP delivers LSProbe Multiprobe Systems since 2016. ISO11451-5 is based on hardware-synchronized
data, collected with several LSProbe systems.

LUMILOOP’s software evaluates standard-compliant statistics for over 8+ probes, with up to 6 antennas and
500 kSample/s each, in real time! It’s as easy as querying one CDF threshold per frequency.
