TDS H-Field Probes: H1TDSx, H1TDSz

TDS H-field probes are miniaturized active optical magnetic field probes for use in non-magnetic media (μ_r = 1).

For ICEy applications, each TDS time-domain field probe is delivered with 10 cm connector saver and ICEy machine adapter enabling >25,000 mating cycles per probe. All SPEAG TDS probes have been optimized for field measurements over the 10 MHz – 6 GHz frequency range and are individually calibrated and characterized in SPEAG’s ISO17025-certified calibration laboratory.
