LSPM 2.1, 9 kHz – 26.5 GHz

The LSPM 2.1 Power Meters are laser-powered, three channel, high speed, high
accuracy and high dynamic range RF Power Meters. Single and dual channel versions are available as well.
It covers a frequency range from 9 kHz to to 26.5 GHz.
Operation at higher frequencies is supported with reduced performance.

LSPM 2.1 is galvanically isoated. The sensor heads are extremely robust and can withstand more
than 1000 V/m. Measuring forward and reverse RF Power at a directional coupler inside EMC test chambers
has never been easier! Fiber cable lengths of >500 m allow for remote operation without ground loop worries.

Compensation of linearity, frequency and power sensor temperature guarantee accurate measurements from
less than -60 dBm to at least +15 dBm. A dynamic range of >75 dB is achieved for many frequencies.
The LSPM Triple High-Speed Power Meter’s high sampling rate allows for high resolution time-domain signal
analysis. The Power Meters can be synchronized with signal generators in order to realize high resolution pulse
analysis. All LSPMs can also be synchronized with further LSPM 1.0, 1.1, 2.0 and 2.1 Power Meters as well as
LSProbe E-Field Probes.

The LSPM 2.1 Laser-Powered RF Power Meters can also be combined with the Computer Interface
CI-250 + . It is equipped with a 4.3” Touchscreen and Ethernet Interface.
CI-250 + displays RF power, laser status, . . . at a glance. The set up is a child’s play.
Third party EMC software integration is quick and easy – just enter the IP address, power the laser, and start your
measurement.
One CI-250 + enhances other LUMILOOP devices: LSPM 1.0 and LSPM 2.0 as well as LSProbe E-Field Probes.
