enprobe developes and offers sensors for the measurement of RF electric fields.
Their outstanding characteristic is the unparalleled small probe head size combined with an all-optical signal transmission.
This practically makes the sensor invisible to the field - the field distortion caused by the sensor is completely negligible.
But you get a bit more: No matter whether you measure in frequency or in time domain, the probes always deliver the full spectral or temporal information of the field, respectively.
This gives you a lot of new options in post-processing and analyzing your measurement results.
