GW Instek launches a new series of high-frequency LCR meters ~ LCR-8200(A), which has five models and the maximum test frequency is up to 50MHz. The entire series adopts a 7-inch color display and features a high measurement accuracy (0.08%).

The measurement results can be presented numerically or graphically according to the selected measurement mode, allowing users to optimally interpret the characteristics of the DUT. At the same time, a full range of standard interfaces such as USB device / RS-232C / Handler and GPIB allows users to control the instrument by the most familiar interface without worrying about additional hardware investment costs.

Furthermore, the series also provides a USB storage function when operating in graphics mode. The measured characteristic curves and values of the DUT are saved for subsequent analysis. The wide variety of features of the LCR-8200(A) can help users easily respond to the test requirements of passive components in R&D, engineering, and production.

Under the numerical measurement mode, it is divided into MEAS measurement and LIST measurement. Under the MEAS measurement mode, users can select up to 4 (at least 1) desired measurement items from the 17 measurement parameters. Each selected measurement item can be set to compare (PASS/FAIL judgment) or to the BIN function to conduct judgment and sorting so that users can easily learn the results of the measurement by color and sound. Under the LIST mode, users is allowed to set 15 test points and each test point can set parameters independently, including frequency/voltage/bias, and it even can set independent comparison function and numerical display mode (value, difference value, difference percentage). On top of that, under the LIST mode, the automatic trigger mode is also provided. After each LIST measurement is completed, the instrument will be in the mechanism of a stand-by trigger. Users only need to place the next DUT, and the LIST test can be automatically performed which saves time by repeatedly pressing the trigger button.

Under the graphical measurement mode, the SWEEP measurement provides the ability to sweep two parameters simultaneously(TRACE A / TRACE B). The relative parameters of the sweep, including the sweep source (frequency, voltage, current or bias voltage),horizontal / vertical axis scale (LINEAR / LOG), speed...etc., even adding a bias, can be set and tested according to the actual needs of users. Besides, the LCR-8200A series provides 7 different equivalent circuit models which allows user analysis by 3-componentsor 4-components combination to characterize the operational characteristics of the circuit. After the sweep is completed, the scale can be automatically adjusted according to the selected TRACE, so that the whole observation is clearer and easier to read. Other than that, the swept graphics (bmp) and values (csv) can be saved to the flash drive for subsequent analysis and applications.

Whether it is for measurement data collection during the test process or the collocation for the system integration, the LCR-8200 (A)series offers the most comprehensive communications interfaces, including USB device, RS-232C, LAN for PC connection and even GPIB, which are all standard communications interfaces. Users can choose according to their habits of use and the convenience of the system architecture without any additional cost. In addition, the LCR-8200 (A) series also provides a Handler interface for system integration of PLCs or sorters.

1. Different frequency ranges: LCR-8200 provides 5 models, the highest frequency of each model is 1MHz, 5MHz, 10MHz, 20MHz, and 30MHz; and LCR-8200A also provides 5 models, but the highest frequency of each model is 5MHz, 10MHz, 20MHz, 30MHz, and 50MHz.

2. Equivalent Circuit Model Analysis: LCR-8200A provides 7 different equivalent circuit models which are using circuit components to form a specific circuit network, characterize the operational characteristics of the circuit or analysis of its performance, and discover any scope of further modification.
