DC Gain Accuracy Test
CAUTION Ensure that the input voltage to the oscilloscope never exceeds ±5 V.
Specifications
Equipment Required
Let the oscilloscope warm up before testing.
The oscilloscope under test must be warmed up (with the oscilloscope application running) for at least
30 minutes prior to the start of any performance test.
DC Gain Accuracy ±2% of full scale at full resolution channel scale
Full scale is defined as 8 vertical divisions. Magnification is used below 10 mV/div. Below 10
mV/div full scale is defined as 80 mV. The major scale settings are 10 mV,
20 mV, 50 mV, 100 mV, 200 mV, 500 mV and 1 V.
