 +In the demo, the Zmod Scope CH1 is set to High Gain (+/-1V input range). The Zmod AWG CH1 and CH2 are set to Low Gain/Range (+/-1.25V output range).\\ 
 +Therefore, a signal applied to the Zmod Scope CH1 input, converted to numeric format and the result sent directly to the inputs of Zmod AWG will be amplified 1.25V/1V = 1.25 times.\\ 
 +If the user needs the AWG output voltage to have the same range as the Zmod Scope input, the numeric representation received from the Zmod Scope will need to be multiplied in the PL by 1/1.25 = 0.8.
