Siglent RBSSA3X20 Reflection Bridge Instructions - 1

SIGLENT TECHNOLOGIES User Manual Product Introduction RBSSA3X20 Reflection Bridge Instructions The Siglent RBSSA3X20 is used in connection with SIGLENT's SSA3000X series of spectrum analyzers to measure Sll-related parameters such as return loss, reflection coefficient and VSWR. The RBSSA3X20 also provide 2 N(M)-N(M) adapters to facilitate connection with SSA3000X's ports. The reflection bridge has 3 ports as shown in the figure: -IN(TG):Signal input terminal.This terminal connects to the TG terminal of -OUT(RF):Signal output terminal. This terminal connects to the RF input terminal of the spectrum analyzer -DUT: This port is connected to the Device Under Test The distance between the SSA3000X's TG and Input ports is designed to match that on the RBSSA3X20 in order to improve accuracy by eliminating the need for extra hook-up cables. Refleclion Bridge Measurement Procedure The connection of RBSSA3X20 and spectrum analyzer is shown in the Use 2 N(M)-N(M) adapters to connectthe output terminal of the tracking generator and the RF input terminal I of the spectrum analyzer to the IN terminal and OUT terminal of the reflection bridge respectively. 1) Press Mode->Reflection Meas, to access the Reflection Measurement mode. The Tracking Generator Tracking Generator indicator light will activate and the screen will appear as below: Reflection Table Disconnect the DUT before press the "Cal Open Load', Connectthe DUT when the "Cal Open Load' pressed. 2) In the Reflection Measurement mode the user can modify certain spectrum analyzer parameters such as Frequency, Amplitude, and BW, in those related menus.
