E1TDS - TDS E-Probes

TDS E-Field Probes: E1TDSx/MRI, E1TDSz/MRI

TDS E-field probes are miniaturized active optical electric field probes for use in free-space media (εr = 1). For standalone applications (far- and near-field), each TDS time-domain field probe is delivered with an 8 m rugged fiber-optic cable attached directly to the probe. All SPEAG TDS probes have been optimized for field measurements in the frequency range from 10 MHz to 6 GHz and are individually calibrated and characterized in SPEAG’s ISO17025-certified calibration laboratory.
Types of Probes

E1TDSx/MRI*
Single-axis free-space probe, sensitive to E-fields radial to the probe axis

E1TDSz/MRI*
Single-axis free-space probe, sensitive to E-fields parallel to the probe axis
