H1TDS SNI - TDS H-PROBES

H-Field TDS Sniffer Probe : H1TDSx SNI, H1TDSz SNI

H-Field TDS SNI are small-form-factor, hand-held, high-performance probes for magnetic near-field EMC/EMI/ESD sniffing applications. Based on SPEAG's novel TDS technology, each probe incorporates an active optic fully isolated micro-loop sensor that guarantees high sensitivity and high resolution in the 10 MHz – 10 GHz frequency range. Its excellent E-field rejection allows precise H near-field mapping free from undesired E-field contributions. The superior RF EM transparency, due to the absence of conductive parts that could shield or perturb the field under measurement, allows effective and reliable EMC/EMI/ESD pre-compliance tests. All TDS SNI sniffer probes are calibrated in SPEAG’s ISO17025-certified calibration laboratory and are delivered with traceable calibration certificates.
