R3765/67G series is the 3.8GHz/8GHz vector network analyzer, which has newly been designed based on a concept “an optimum tool for each application”. We have fully pursued high throughput such as 0.15ms/points high-speed measurement at a resolution bandwidth (RBW) of 20kHz, 10OdB wide dynamic-range measurement, and two-device simultaneous measurement with four-channel/eight-trace display. Also, we have added the program sweeping function that can freely change the resolution bandwidth (RBW) and output level during sweep operation for each segment. With the built-in BASIC controller, a high-speed ATE system can be easily configured with no external controller for processes from adjustment to inspection. <Features> (1) High throughput • (2) Wide dynamic range • (3) 100dB wide dynamic range. Program sweeping function. • (4) For the С type, four S parameters can be displayed simultaneously using a high-speed frequency sweep of 0.15 ms/point and the 4ch/8 trace. For each segment, allows setting of frequency, output level, RBW and settling time. MS-DOS formatted disk • • By using an MS-DOS personal computer, it is possible to easily create programs and analyze data because of the disk conformed to MS-DOS format standard. Three modes of storage capacity available (DD 720KB, HD 1,2MB, HD 1.4MB).
