SPI7 Rohde&Schwarz R&S ESPI7 receiver ESPI7 Content: R&S | ESPI7 | EMI Pre Certification Test Receiver | Rohde&Schwarz | EMC Receiver | 9KHz to 7GHz Brand: Rohde&Schwarz, Germany | R&S | Rohde&Schwarz There are two models of pre certified R&S ESPI test receivers that integrate all the advantages of Rohde&Schwarz certified EMI test receivers. If the R&S ESPI-K50 option is selected, the test receiver can be used to measure the field strength coverage of communication and broadcasting networks. ESPI7 definition: EMI test receiver is a fully automatic EMI test receiver that integrates antenna and receiver. It is an important equipment for conducting spatial field strength testing, used to measure useless or harmful interference signals in space; At the same time, the field strength of useful radio signals emitted by space radio and television stations can also be measured A receiver is a circuit system consisting of an antenna, a filter, an amplifier, and an A/D converter. The navigation and positioning signals sent by GPS satellites are an information resource that can be shared by countless users. For users on land, sea, and space, as long as they have a receiving device capable of receiving, tracking, transforming, and measuring GPS signals, namely a GPS signal receiver, they can use GPS signals for navigation and positioning measurements at any time. According to different usage purposes, the GPS signal receiver required by users also varies. At present, there are dozens of factories in the world producing GPS receivers, with hundreds of different products. These products can be classified according to their principles, purposes, functions, etc. Receiver measurement refers to the measurement of various performance parameters of a receiver during the inspection, acceptance, and maintenance of finished products R&S ESPI - Model -- R&S ESPI3: 9 kHz to 3 GHz -- R&S ESPI7: 9 kHz to 7 GHz R&S ESPI - Multiple Applications --EMI diagnostic measurement, production, quality assurance, repair and maintenance during the R&D phase --Pre certification and post certification testing that comply with all civilian EMI standards --Quick and easy interference testing in mobile applications --Evaluate field strength coverage with extremely fast measurement speed --As a spectrum analyzer, including selective input ESPI7 features: The limit values of different standards can be set and modified arbitrarily, with simple methods and complete functions. Transmission factor instruments can be selected according to different accessories to automatically process data. Perform scanning and rough measurement, and simultaneously measure two curves of peak and average values; It is also possible to measure the average or peak curve separately. The instrument can perform final testing, measuring the quasi peak and average values of a maximum point in each frequency band; It is also possible to manually select points for final measurement of quasi peak and average values. Automatic peak value measurement can be performed on frequency points that exceed the standard, and the dynamic changes of peak values at individual frequency points can be observed. The intuitive graphical energy bar displays the terminal test voltage value and has the function of maintaining the maximum value. The instrument can provide a test report of the results, which can include information about the testing personnel. The report can be printed directly in writing or saved in electronic format. The report can be output through a USB port, and the report format is a universal format that can be transmitted over the network. The software design is more humanized, and the upper and lower limits can be adjusted during the test to achieve the best display effect. It can also zoom in on any range to observe test data more accurately. Rich help information helps users have a deeper understanding of the various functions of the device.
