If you want to make the correlation coefficient to be 1 for multiple signals, you need the following procedure
1, Open SR5500 TestKi, from configuration - System /communicaiton setup.
(1) goto System - System Mode: Number of SR5500 instruments controlled by TestKit: select the numbers of the SR5500 you want to control.
(2) goto Synchronization mode : Synchronize Play/Pause/Stop across units: Active
(3) Correlation coefficient : System based, Correlection Coefficent type: Complex
2, Click ok and after several seconds, the settings are applied, goto Correlation Editor, Correlation Mode : Complex
You will need to input the coefficient for every line to be 1.0000+0.0000j, apply after the value have been changed.
