With a frequency range from 100 kHz to 300 MHz, the IM7581 supports characterization of components such as power inductors, common-mode filters, ferrite components and filter structures. Measurement Performance and Analysis Functions With a basic accuracy of ±0.72% of impedance and ±0.41° of phase, the IM7581 is designed for precise impedance measurements up to 300 MHz. Test signal levels from −40.0 dBm to +7.0 dBm support measurement conditions that require higher excitation of the device under test. Typical repeatability of approximately ±0.07% supports reproducible measurement results under defined conditions across its entire frequency range. A typical measurement time of 0.5 ms enables fast frequency sweeps without compromising measurement stability. 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 further analysis, the IM7581 provides an equivalent circuit analysis function with representative circuit models and automatic model selection based on measurement data. This supports impedance and resonance evaluation of components within its specified frequency range.Test Head and Fixtures The IM7581 employs a compact, palm-sized test head connected to the main unit by 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 measurements. This design supports stable and reproducible results up to 300 MHz while reducing bench space requirements in high-frequency measurement environments. For measurements of components with different package types, the IM7581 is typically used in combination with the IM9202 test fixture. The IM9202 is designed for impedance measurements up to 600 MHz and supports both surface-mount and leaded components with 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 inductive and filtering components within the specified frequency range. For stable mounting, the IM9202 test fixture is mounted on the IM9200 stand. The stand 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 IntegrityWith the optional IM9905 calibration kit, OPEN, SHORT and LOAD reference standards are available to correct system-related errors in high-frequency impedance measurements up to 3 GHz. The calibration addresses parasitic influences within the measurement path up to the specified reference plane, including the analyzer test head and its interfaces. The calibration standards are connected via the IM9906 adapter, which is shared with test fixture connections.Integrated contact check functions, including DCR testing, Hi-Z reject and waveform verification, are used to assess contact quality before and, if necessary, after measurement. This reduces the risk of invalid results caused by poor electrical contact or unstable component positioning. Developed and manufactured in Japan, the IM7581 is intended for reliable long-term operation in measurement and test environments with high requirements for stability over time.

The IM9905 calibration kit provides OPEN, SHORT and LOAD standards for calibration of HIOKI impedance analyzers with two-terminal measurement capability at the 7 mm (APC-7) reference plane. These standards are used to correct systematic measurement errors in the measurement path up to this reference plane. For calibration of impedance measurement systems, the 7 mm (APC-7) reference plane is commonly applied in high-frequency metrology. When calibration is performed on systems with a 3.5 mm test head, such as those of the HIOKI IM7587, IM7585, IM7583 or IM7581, a suitable adapter is required to establish the 7 mm reference plane. The adapter provided by HIOKI for this purpose is the IM9906.

The IM9201 SMD test fixture is designed for impedance measurements of surface-mount components (SMD) in combination with HIOKI impedance analyzers that support twoterminal measurement configurations. It supports measurements up to 3 GHz and accommodates SMD component sizes from EIA0201 to EIA1210.The IM9201 supports measurements up to 3 GHz, which aligns with the frequency range of high-frequency impedance analyzers such as the IM7587 and IM7585. The test fixture can also be used with impedance analyzers featuring lower maximum measurement frequencies, such as the IM7583 or IM7581, when measurements of small SMD component sizes below EIA0603 are required.For stable operation, the IM9201 is mounted on the IM9200 stand, which provides a secure base and defined mechanical alignment between the analyzer test head and the test fixture. Handling of small SMD components is further facilitated by the magnifier supplied with the IM9200 stand. Electrical connection to the analyzer test head is performed via the 7 mm interface of the test fixture. 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. The IM9201 is supplied with a carrying case designed for storage and transport of the test fixture and its included accessories. The carrying case also provides dedicated space for optional accessories such as the IM9906 adapter and IM9905 calibration standards, allowing related components to be stored together when required.

The IM9200 is a stand for the impedance test fixtures IM9201 and IM9202. It provides a stable mechanical base and a defined alignment between the analyzer test head and the mounted test fixture. Handling of small components during setup and measurement is supported by the removable magnifier supplied with the IM9200. When not in use, the magnifier can be stored in the carrying case of the test fixture.
