The miniaturized LSProbe E-Field Probes ensure unattended, uninterrupted measurements combined with high resolution, high speed and low noise over the entire test period.
With the galvanically insulated power supply, the need for batteries is now eliminated. The field probes do not only measure average values but the time course of fields. With an unprecedented wide dynamic range and fast pulse response, LSProbe provides the user completely new measuring options.
LSProbe allows for a higher efficiency through faster, shorter and lower-cost testing intervals.
Two different types are available:
Features of LSProbe
- Frequency range from 10 Hz – 26.5 GHz
- Unrivaled measurement speed (radar pulse measurement)
- Highest measurement accuracy (linearity and resolution)
- Greatest dynamics over the entire frequency range
- Reliable and fail-safe design
- No start-up time
- Immediately ready for use
- Customer oriented warranty and service conditions
- Accredited calibration
