TDS SNI System

System

TDS SNI is composed of one or more TDS SNI probes for electric or magnetic near-field sniffing and a TDS Remote Unit.

Applications

The TDS SNI system is optimized for near-field  EMC/EMI/ESD sniffing using SPEAG's novel time-domain sensor technology, including:

• Measurements in EM-harsh environments
• EMC/EMI/ESD near-field quantitative measurements
• EMC/EMI/ESD pre-compliance tests
• Measurement of the full complex-valued vector field in the very close near-field of radiators
• In situ base station compliance measurements

The basic configuration of a TDS SNI system is composed of:

• a TDS Standalone Remote Unit
  
• a TDS SNI H1TDS magnetic or E1TDS electric field probe
• 3.5 mm RF coaxial cable (length 0.6 m)
• ClickCleaner (optical connector cleaner)
• USB cable
• USB power supply
• TDS Professional Handbook
