FSP-38 9kHz至40GHz频谱分析仪
罗德与施瓦茨公司的FSP-38频谱分析仪是一种宽带,非常灵敏的接收器。它基于“超外差接收机”的原理工作,该接收机可以将较高的频率(通常高达数十GHz)转换为可测量的数量。接收到的频谱缓慢扫过一系列预选频率,将所选频率转换为可测量的DC电平(通常为对数刻度),并在Rohde&Schwarz,Inc. FSP-38的CRT上显示频谱。 CRT显示相对于频率(x轴)的接收信号强度(y轴)。
罗德与施瓦茨公司(Rohde&Schwarz,Inc.)FSP-38频谱分析仪的某些应用包括站点监视:验证发射机频率和信号强度的准确性。干扰:安装系统之前,请使用Rohde&Schwarz,Inc. FSP-38频谱分析仪来验证未使用(计划的)频率,或者是否有强信号干扰新设置。干扰可能是由许多不同情况引起的。利用Rohde&Schwarz,Inc. FSP-38频谱分析仪功能的其他测试包括天线隔离,同信道干扰,相邻信道功率,占用带宽,互调,微波或卫星天线对准以及组件表征。
FSP-38 9kHz to 40GHz Spectrum Analyzer
The Rohde & Schwarz, Inc. FSP-38 spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Rohde & Schwarz, Inc. FSP-38. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Rohde & Schwarz, Inc. FSP-38 Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Rohde & Schwarz, Inc. FSP-38 spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Rohde & Schwarz, Inc. FSP-38 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
