ADVANTEST  R3765G/3767G Series  Network Analyzers

Network Analyzers

The R3765G/67G-series network analyzers are vector network analyzers that incorporate a new RF circuit analysis technique. The measuring frequency range is from 300 kHz to 3.8 GHz (R3765G)/ 300 kHz to 8 GHz (R3767G). ADVANTEST's unique high-speed signal processing technology enables a faster measurement speed. In addition to the basic model, a model with built-in bridge transmission/reflection characteristic measurement and a model with a built-in S-parameter test set for forward and reverse measurement are also available. An optional 3-port test set or 4-port test set can be added to these models. By installing additional input channels in the receive section, the multi-port models allow perfectly simultaneous measurement of two different measurement paths, revolutionizing the measurement efficiency of multiport devices. The 8.4-inch color TFT liquid crystal display allows the waveform display can be split into four windows. An independent measurement path can be selected for each windows, thus allowing the simultaneous display of up to eight parameters in four paths. Analysis of measurement items in a wide range can be completed instantaneously. By executing 2-port full calibration, measurement speed can be increased to 0.15ms per point. The optional software fixture function makes measurement of normalized impedances other than 50Ω easy. This function converts the impedance in software, eliminating the need to provide hardware such as an impedance converter. Furthermore, balanced circuits can be measured and matching networks such as filters and amplifiers can be simulated using the network analyzer, making it suitable for wide range of applications. ADVANTEST's popular BASIC controller function is incorporated in the analyzer as standard, expanding the analyzer's applications in automatic measurement.

■ Revolutionized measurement of multi-port devices Thanks to additional input channels, the built-in 3-port test set model (option) can shorten measuring time. The system eliminates the need for a change-over switch and enables measurement of two different paths simultaneously. For example, the new system obtains measurement results in two sweeps for Tx and Rx measurement of a duplexer, compared with the four sweeps normally required. 

■ High-speed sweep time The sweep time per point has been shortened further to 0.15ms. The network analyzer also features faster register save and recall functions in addition to reduced sweep time to enhance overall throughput. 

■ Software fixture (option71/72) In conventional RF measurement normalized impedance has been limited only to 50Ω. A function has been added that eliminates the need for a hardware fixture to establish the system of measurement.

■ High-Speed, High-Accuracy Measurement

The R3765G/3767G series achieves a further reduction of measuring time. This series of network analyzers supports today's increasingly diverse measurement environments and significantly expands RBW setting resolution to enable optimal setting for both high-accuracy and high-speed measurement. 

• 0.15ms/point in 2-port full calibration 

• full calibration : 3-port and 4-port 

• High-speed data transfer 

• Enhanced IF RBW setting resolution at 20 kHz to 10 Hz

■ Easy Operation Rapid increase in the performance and the number of ports in modern devices not only make using measuring equipment more complicated, but also greatly increase the number of items to be analyzed. One of the most important features of network analyzers in the recent years is the ability to enhance the efficiency of analysis. Focusing on this requirement, the user interfaces of the R3765/ 67G series have been dramatically enhanced. 

• Automatic calibration kit 

• Ten markers per trace 

• Easy-to-see limit line editor and powerful GO/NO-GO functions

■ Revolution in Multi-Port Measurement As options, a model with a 3-port test set and a model with a 4- port test set are available in the R3765/67G series. These options not only contain the test sets, but also have an additional network analyzer receiver channel. This enables simultaneous measurement of two different paths, such as the Tx and Rx of a duplexer, without a switching time. A 3-port full calibration function is available to enable measurement of 3-port devices more accurately. This function is useful for measuring couplers and circulators and can greatly enhance the accuracy of measurement. displayed simultaneously also.
