Teseq Inc., a developer and provider of instrumentation and systems for EMC emission and immunity testing, now offers two new USB / RS232 electric field probes. The PMM EP-600 and EP-601 active broadband field probes benefit from a true spherical symmetrical dipole configuration. Sampling at a rate of 22 S/s to 0.03 S/s depending on filter settings, the probes’ 6 monopole sensors sample data simultaneously on an X-Y-Z axis. The digital filter can be preset to 2.3 Hz to 28 Hz or low pass in response to the specific application requirements.
