虚拟式VXI仪器已使用很多年了。高频生产线上大容量测试的需求,促使微波仪器生产厂家大力支持这种类型的仪器。HP公司的E6432A型微波频率合成器是VXI总线的快速切换和编程灵活的模块。它的工作频率从10MHz～20GHz,频率分辨率1Hz,切换速度优于400μS。 HP E6432A是C尺寸,三插槽的寄存器基VXI模块,使用快调谐微波压控振荡器(VCO)以及信号漂移消除电路,使用寄存器基处理电路简化系统中的存取和加快切换速度。400μs的频率切换速度是指工作频带内任意两个频率之间的切换时间。若两频率相差在50kHz之内,切换时间只用270μs。 VXI频率合成器标准配置能输出功率电平从-20～+17dBm。配合一系列选件,输出功率电平还可以-90
Virtual VXI instruments have been used for many years. The demand for high-capacity testing of high-frequency production lines has prompted microwave instrument manufacturers to strongly support this type of instrument. HP’s E6432A Microwave Frequency Synthesizer is a fast-switching, programming-flexible module for the VXI bus. Its operating frequency from 10MHz ~ 20GHz, frequency resolution 1Hz, switching speed better than 400μS. The HP E6432A is a C-size, three-socket register-based VXI module that uses a fast-tuned microwave voltage-controlled oscillator (VCO) and signal-drift cancellation circuitry that uses a register-based processing circuit to simplify system access and speed up switching. The frequency switching speed of 400μs refers to the switching time between any two frequencies in the working frequency band. If the difference between the two frequencies within 50kHz, switching time only 270μs. VXI frequency synthesizer standard configuration can output power level from -20 ~ +17 dBm. With a series of options, the output power level can also -90
