Detailed Product Overview

Analysis of HF components in a wide range of electronic applications regularly requires impedance measurements up to several hundreds of megahertz. With a frequency range from 1 MHz to 600 MHz, the IM7583 supports characterization of components such as chip inductors, ferrite beads, filters and resonators in HF circuit design. 

Measurement Performance and Analysis Functions

High measurement accuracy of ±0.65% for impedance and ±0.38° for phase ensures reliable impedance evaluation across the specified frequency range. A typical repeatability of approximately ±0.07% provides reproducible results under defined measurement conditions. Fast frequency sweeps are supported by a typical measurement time of 0.5 ms, while test signal levels from −40.0 dBm to +1.0 dBm allow controlled excitation of the device under test. 

The analyzer supports LCR, sweep and continuous measurement modes and provides evaluation functions such as comparator and BIN judgment, as well as area, peak and spot analysis. All measurement settings and analysis functions are accessed directly via the integrated 8.4 inch color touchscreen. Standard interfaces include USB, LAN and EXT I/O, with optional RS-232C and GP-IB. 

For extended analysis, the IM7583 provides an equivalent circuit analysis function with multiple representative circuit models and automatic model selection based on measured data. The available models support impedance-based evaluation of HF components and enable systematic characterization across frequency sweeps. 

Test Head and Fixtures

The IM7583 employs a compact, palm-sized test head connected to the main unit via a specified connection cable. It is available with 1 m or 2 m cable lengths, allowing users to balance measurement accuracy and installation flexibility. Placing the test head close to the device under test minimizes signal path length and reduces parasitic inductance and capacitance that would otherwise affect high-frequency impedance measurements. This design supports stable and reproducible results while reducing bench space requirements in laboratory environments. 

For measurements of components with different package types, the IM7583 is typically used in combination with the IM9202 test fixture. The IM9202 supports impedance measurements up to 600 MHz and is designed for both surface-mount and leaded components, providing a stable two-terminal contact interface. Defined contact geometry ensures reproducible placement of the device under test and reliable electrical contact, reducing measurement variation and enabling accurate characterization of HF components. 

For dedicated SMD measurements, the IM7583 can also be used with the IM9201 SMD test fixture. For stable mounting, the selected test fixture is mounted on the IM9200 stand, which provides a secure base and a defined mechanical connection between the test head and the fixture and includes a magnifier to facilitate handling of small components. The IM9906 adapter is required to connect the 7 mm interface of the test fixture to the analyzer test head’s 3.5 mm connector. 

Calibration and Measurement Integrity

The optional IM9905 calibration kit provides open, short and load reference standards for correction of system-related measurement errors. By compensating for parasitic effects introduced by fixtures and the test head, the kit supports stable measurement accuracy over time. Connection of the calibration standards is performed via the same IM9906 adapter used for the test fixture. 

The optional IM9905 calibration kit supplies OPEN, SHORT and LOAD reference standards for reducing system-related measurement deviations in high-frequency impedance measurements up to 3 GHz. Calibration is applied to the measurement path up to the defined reference plane, covering the analyzer test head and the associated connection interfaces. The calibration standards are connected using the IM9906 adapter, which is also used for test fixtures
