Chapter 4: Testing Performance

DC Gain Accuracy Test

Calculate the offset gains for the 50 W test and the 1 MW test using the following expression

and record this value in the DC Gain Test section of the Performance Test Record.

For the 50 W input impedance version of this test at the 5 mV/div sensitivity, use the

following equation:

All vertical sensitivities for the 1 MW test (including the 5 mV/div setting) and all 50

W test vertical sensitivities except for the 5 mV/div setting should then use the following

equation:
