RF Vector Signal Generator(VSG) versus Vector Signal Analyzer(VSA)

This page on RF VSG vs RF VSA describes difference between RF VSG and RF VSA with respect to test and measurement.VSG stands for Vector Signal Generator and VSA stands for Vector Signal Analyzer.

RF VSG

It is basically vector Signal Generator which generates baseband IQ vector for various modulated signals as per wireless standards viz. WLAN,WiMAX,Zigbee,GSM,CDMA,LTE and more. It is available in various flavors i.e. in different ways as per user need. Following are well known deliverables provided by Test and Measurement Companies such as Agilent,National Instruments,R&S,Anritsu,Litepoint and more.

Offline VSG Application: It generates IQ vector in various formats(floating point,fixed point and more). Can be saved in a file and the same can be played on realtime RF instrument or can be loaded to any VSA(Vector Signal Analyzer) application in offline mode manually.

RF VSG: It generates modulated RF vector so that it can be used to cross check realtime DUT's Receiver's performance/functionality. Most of the RF VSGs provides facility to load external IQ file to be played and will in turn generates modulated RF signal.

RF VSA

It is basically vector Signal Analyzer which analyzes baseband IQ vector of various modulated signals as per wireless standards viz. WLAN,WiMAX,Zigbee,GSM,CDMA,LTE and more. It is available in various flavors i.e. in different ways as per user need. Following are well known deliverables provided by Test and Measurement Companies such as Agilent,National Instruments,R&S,Anritsu,Litepoint and more.

Offline VSA Application: It analyzes IQ vector in various file formats(floating point,fixed point and more). Decoded data can be saved in a file and compared with standard expected data.

RF VSA: It generates analyzes RF vector so that it can be used to cross check realtime DUT's Transmitter's performance/functionality.
