HZ16 Rohde & Schwarz

Version 01.01 May 2006 Probe Set HZ-15 for E and H near-field emission measurements with test receivers and spectrum analyzers 30 MHz to 3 GHz Special, electrically shielded magnetic field probes Probe tips adapted to near-field measurement High-resolution measurements Easy-to-determine magnetic field orientation Easy operation and handling Data sheetE and H near-efi ld measurements on electronic modules Near-field measurements are often performed, if a developer has to find out why an emission limit of an EMC standard is exceeded, for example. Based on field strength measurements, the developer already knows several critical frequencies of the device or module under test. A practical way to reduce EMI is to analyze near fields, locate the sources and come up with targeted countermeasures. Near-field Probe Set HZ-15 with Spectrum Analyzer FSH 3 and Preamplifier HZ-16 Special Probes HZ-15 and are ideal for measuring high- is determined by the size and design frequency fields starting at 30 MHz on of the probe tip. All probes are passive Before you perform a near-field analysis, printed boards and on components. The and are connected to the 50 W input you first need to know how the E and magnetic field probes include special of a test receiver or spectrum analyzer. H fields are distributed. The five probes electrically shielded probe tips. The The Preamplifier HZ-16 increases from the Probe Set HZ-15 are well various probe tip shapes are designed sensitivity. suited for this purpose. All near-field for tasks in near-field measurements. probes are designed for ease of use, The upper limit frequency of a probe Preampliefi r HZ-16 Inserting the Preamplifier HZ-16 between the near-field probe and the spectrum analyzer makes it easier to measure very weak high-frequency fields of up to 3 GHz. The input and output are provided as 50 W BNC connectors to allow you to use any spectrum analyzer.
