TDS SNI System

The Time Domain Sensor SNIffer (TDS SNI) probes are miniaturized, active, fully isolated magnetic and electric near-field probes that perform over a very broad frequency range, from 10 MHz –10 GHz. SPEAG’s TDS technology operates in both the frequency and time domains, delivering unparalleled sensitivity and spatial resolution for precise amplitude and phase measurements. TDS provides tremendous advantages over traditional conductive EMC probes in all near-field applications where EM transparency and noise and interference immunity are essential. All TDS systems are calibrated in SPEAG’s ISO17025-certified calibration laboratory.
