minal (2) will appear. When the M O D E switch
(6) is set to C H 2 , then the input signal to
INPUT terminal (10) will appear on the scope.
When the M O D E switch (6) is set to D U A L ,
two waveforms (CH1 and CH2) will appear on
the scope, at this time, the CH1 signal to the
INPUT terminal (2) is fed to the syncro circuit
where the CH 1 signal is synchronized. When
the M O D E switch (6) is set to A D D , the CH 1
signal is algebraically added to the CH2 signal
(CH 1 +
