Rohde & Schwarz HZ-17 H Near-Field Probe Set

Overview

The Rohde & Schwarz HZ-17 is a passive near-field probe set designed for detecting and analyzing magnetic (H) fields in the frequency range from 30 MHz to 3 GHz. It includes two H-field probes with different configurations to address various measurement scenarios. The electrically shielded magnetic field probes enable developers to locate EMI sources on printed circuit boards and modules without disturbing the device under test.

Key Features

• Frequency range from 30 MHz to 3 GHz
• Two H-field probes: RSH400-1 (loop, 25 mm diameter) and RSH2.5-2 (selective, 0.5 mm groove)
• Electrically shielded probes with easy magnetic field orientation determination
• 50 Ohm SMB (female) output connector
• Isolation voltage: 60 V DC / 42.4 V AC (peak)
• Maximum RF input power: RSH400-1 (4 W), RSH2.5-2 (0.5 W)
• Passive design—no external power required

Applications

• Near-field EMI troubleshooting and source location
• Immunity testing with controlled field exposure
• EMC pre-compliance measurements
• Detection of current spectrum in conductor traces and component leads
• Module and instrument emission analysis

Included Accessories

• RSH400-1 H-field probe with large loop (25 mm)
• RSH2.5-2 H-field probe with selective tip (0.5 mm groove)
• 1 m RF cable with BNC (male) and SMB (female) connectors
• RF adapter with N (male) and BNC (female) connectors
• Robust plastic protective case
