Infiniium V-Series Oscilloscopes Service Guide 33
DC Gain Accuracy Test
CAUTION
Ensure that the input voltage to the oscilloscope never exceeds
±5 V
.
NOTE
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.
Specifications
DC Gain Accuracy ±2% of full scale at full resolution channel scale (±2.5% for ≤ 5 mV/div).
Full scale is defined as 8 vertical divisions. Magnification is used below 7.5 mV/div. Below 7.5
mV/div, full scale is defined as 60 mV. The major scale settings are 1 mV/div, 2 mV/div, 5 mV/div, 10
mV/div, 20 mV/div, 50 mV/div, 100 mV/div, 200 mV/div, 500 mV/div, and 1 V/div.
