Overview
The LSPM 2.0 High-Speed Power Meter is a three channel, high speed, high accuracy and high dynamic range RF Power Meter. Single and dual channel versions are available as well. Its frequency range is 9 kHz to 26.5 GHz.Operation up to 40 GHz is supported with reduced performance.
Compensation of linearity, frequency and an actively controlled power sensor temperature guarantee accurate measurements from less than ‑75dBm to at least +12dBm. A dynamic range of >80dB is achieved for many frequencies.
The LSPM 2.0 Triple High-Speed Power Meter’s high sampling rate allows for high resolution time-domain signal analysis. The Power Meter can be synchronized with signal generators in order to realize high resolution pulse analysis.
LSPM 2.0 High-Speed Power Meters can be combined with LUMILOOP’s LSProbe E‑Field Probes to accelerate standard EMC measurements such as IEC61000‑4–3 and 61000–4‑21 by a factor of more than 100 over traditional setups. Rearward connectors are available upon request.
