ADVANTEST R3860 RF Component Analyzer

ADVANTEST R3860 RF Component Analyzer

OVERVIEW

The R3860 RF Component Analyzer is most suitable for evaluating the performance of RF components in the frequency band from 300 kHz to 8 GHz. The R3860, which has functions for measuring multiport devices, such as balanced input/output devices and front-end modules. ADVANTEST has been able to attain the world’s fastest sweep of 10 µs/point, which is a tenfold increase over earlier ADVANTEST products. In addition, it is possible to greatly improve production throughput for mobile terminal components by using the removable panel, which can be installed at a location convenient for the operator, as a tool built into automatic inspection machines.

High-speed, High-accuracy Measurements Using the R3860 RF Component Analyzer

The R3860 is a component analyzer based on a new design concept. Because the R3860’s measurement accuracy is at least three times greater than previous ADVANTEST products— the result of the low-noise design in the receiving section—high-speed sweeps are now possible with an extended resolution bandwidth. At the same level of accuracy as previous ADVANTEST products, your testing costs are significantly reduced.

● Frequency range: 300 kHz to 8 GHz 

● Sweep time: 10 µs/point 

● Resolution bandwidth: 10 Hz to 400 kHz 

● Trace noise: 0.005 dBrms (typical) @ RBW of 100 kHz

Easy-to-View Display Function and Simple Operation

Excellent Flexibility and Visibility

The R3860 is provided with a touch screen function that is installed in a large, 12.1-inch SVGA color LCD display. Up to 16 split windows and up to 32 measured traces can be displayed, giving you the capability to combine S-parameter and format. When adjusting the balanced type of multi-port devices and dielectric duplexer with many traces, and the marker function, operator efficiency improves because of the excellent visibility provided by the high-resolution, largescreen SVGA display.

Eight Independent Channels

The use of the R3860 increase significantly when split windows (up to 16) and measurement traces (up to 32) are used together with eight independent channels. For example, the R3860 is ideal for measuring devices such as multiport devices, each of which requires a set of unique measurement conditions for each channel since a set of measurement conditions and calibration data can be set for each channel. Because many parameter types and measurement results can be observed at a glance, test throughput is dramatically improved.

Simple Operation

‍

The R3860 can be operated either from the touch panel or with a mouse. Both capabilities are provided as standard. The R3860 is easy and simple to operate because measurement data, setting conditions, and other information are displayed on the display unit. Furthermore, you can change setting conditions on the touch panel via the Windows® GUI. These features make it possible for a new user of the R3860 to operate it easily.

Superior Calibration Function

Four-port calibration

Two types of calibration are provided: normalizer calibration which normalizes frequency characteristics only, and full calibration which corrects for impedance mismatch errors in addition to normalizing frequency characteristics. The R3860 performs full calibration appropriate for each of its four ports. The full calibration connection must always be used if low-loss balanced RF devices or multiport devices must be measured with a high degree of accuracy.

Automatic Calibration Kit (Option)

Calibration is always required before highaccuracy measurements are made. Automatic calibration kit enables the unit to obtain a set of stable and accurate calibration data, free of human error. The kit is especially useful for improving productivity because any operator can easily perform highly accurate error calibration. Measurement efficiency can also be improved with alarms generated by the verification function, which automatically and quickly checks whether error corrections are within the specified range, while it is being executed after automatic calibration has been completed.

Multiport Device Measurement

The following devices are available for three-port and four-port devices used in cellular phones in mobile telephone systems: duplexers, circulators, baluns, couplers, dual filters, and balanced input/output devices. In addition, antenna switch modules for five to 12 ports are available for multiband systems. Complexity of the S-parameter representing measurement paths in these multiport devices increase every year.

Per-port Architecture

The R3860 is compatible with up to 4 ports and is designed to simultaneously analyze the signal for each port. As a result, sweep and measurement times can be dramatically reduced. In addition, the combination of measurement paths for a multiport device can be optimized as needed for the purpose of each device.

Easy Display of Many S-parameters

The R3860 is equipped with a large 12.1-inch screen and eight independent channels, each of which can be individually calibrated with a unique set of calibration data. In addition, up to 16 split windows and up to 32 traces can be displayed. When a four-port device is used, all measurement results can be acquired at the same time by combining all 16 S-parameters with the format function. The format function is suitable for multiport devices that have many measurement paths.

Test Adapter Compatible with Up to 12 Channels (Option)

The transmission and reflection characteristics of a multiport device which has a maximum of 12 channels can be measured if the R3968 Series Test Adapter is used together with a the R3860 RF Component Analyzer and OPT14 (four built-in ports). The combination of the R3968 and OPT11 (9-port test adapter) is most suitable for measuring multiport devices, such as dual bandcompatible couplers and triple band-compatible antenna switch modules. In addition, the cost for software development can be cut dramatically if you also runs versatile application programs (written in Visual Basic) which come with the analyzer.
