In the field of communications, digital signal generators are widely used, and the digital signal generators used are vectors. A vector signal generator for modulation (also known as complex modulation or IQ modulation) scheme. Vector modulation is a powerful tone The scheme can generate arbitrary carrier phase and amplitude. In this modulation scheme, the baseband digital information is separated into two Independent components, I (in-phase) and Q (quadrature) components, which are then combined to form a baseband modulation Signal. In recent years, the world famous electronic measuring instrument manufacturer, its digital signal generator, the name Has been replaced with "VectorSignalGenerator", the Chinese name is "vector signal generator", based on this specification The calibration object is a vector signal generator, and the revised specification name is "Vector Signal Generator Calibration Specification". This specification is drafted and revised in accordance with JJF 1071-2010 “Rules for the Preparation of National Metrology Calibration Specifications”. Harmony and adoption of JJF 1001-2011 "General Measurement Terms and Definitions", measurement uncertainty basis JJF 1059.1-2012 "Measurement and Expression of Measurement Uncertainty" was prepared. This specification is compared with JJF 1174-2007 "Digital Signal Generator Calibration Specification", except for editorial modifications. The technical changes are as follows. ---The name of the specification was changed from the original "Digital Signal Generator Calibration Specification" to "Vector Signal Generator Calibration Specification" Fan --- The frequency range has been expanded, and the frequency range has been extended from 250 kHz to 6 GHz to 250 kHz. 44GHz; --- Adjusted the type of communication system being calibrated, adding WLAN, Bluetooth, LTE, WiMAX new communication standard calibration method, no longer retains the calibration of PHS, IS-95CDMA old communication system method. In the WLAN 802.11 communication system, multiple modulation methods are involved, and each modulation method corresponds to multiple The same data rate (see Appendix D) is very complicated. In this specification, the higher the data rate, the higher the index. Each modulation method only requires calibration of the digital modulation quality parameters at its highest data rate. The release of previous versions of this specification. ---JJF 1174-2007.
