- 產品特性
- The R&S®HZ-14 probe set for E and H near-field measurements is a tool for detecting EMC trouble spots. It allows the identification and elimination of disturbance sources as well as the detection of spots sensitive to electromagnetic interference at an early stage of product development, which reduces the time to market.
The R&S®HZ-14 is mainly used for diagnosing radiated emissions from printed boards, ICs, cables, leakage spots in shielded enclosures and similar sources of electromagnetic interference. The ergonomic design of the probes ensures easy handling. Radiated emission sources can be easily located owing to the small size of the probe tips.
Since the H-field probes are passive when operated without a preamplifier, they can also be used to find EMI-sensitive components and modules forming part of instruments or printed boards. The effectiveness of RFI suppression measures or the shielding provided by various types of enclosures and designs can be easily tested with the HZ‑14 probe set.

- 設計特色
- H-field probes
The two H-field probes cover the frequency ranges from 9 kHz to 30 MHz and 30 MHz to 1 GHz. They have the directivity of loop antennas and are electrically shielded so that capacitive coupling is suppressed and electric fields are rejected. Each probe comes with typical correction factors to determine the magnetic field strength for an input impedance of 50 Ω of the measuring receiver. This ensures a high reproducibility of measurements. The two H‑field probes are passive and can be operated bidirectionally so that local immunity tests can be performed. It is therefore possible to induce currents into lines and test signals into components by applying a known signal source to the probe input.
E-field probe
The active E-field probe is designed for omnidirectional signal reception over the entire frequency range. When approaching a radiation source, the probe is capacitively coupled. The E-field probe is powered by the included DC supply.
DC supply
The E-field probe is operated on DC power. It can be powered from almost all Rohde & Schwarz measuring receivers and spectrum analyzers. The corresponding connecting cables are included in the equipment supplied.
Test jig
An included test jig allows functional testing of the H‑field probes as well as simplified normalization of H-field measurements using tracking generators integrated in the measuring receivers and spectrum analyzers. The test jig includes a terminated stripline shaped to take up H-field probes.
Broadband preamplifier
The 30 dB broadband preamplifier improves the S/N ratio in low-level measurements using H-field probes. Providing a gain of 30 dB in the frequency range from 9 kHz to 1 GHz, it has a noise figure of typ. and a 1 dB compression point of 8 dBm (output level). It can be powered from almost all Rohde & Schwarz measuring receivers and spectrum analyzers using the supplied connecting cables.
