4.1.2 Analysis mode
The analysis mode specifies the method in which the measurement data (V1, V2 and  ) are to be
analyzed and processed. There are four (4) analysis modes, i.e., (CH1/CH2), (CH2/CH1), (CH1)
and (CH2), one of which should be set through the menu [Graph][FORMAT][ANALYSIS
MODE].
The result of analysis is given by the gain and phase for the analysis modes, (CH1/CH2) and
(CH2/CH1), and by voltage amplitude and phase for the analysis modes, (CH1) and (CH2).
