Dc Gain Accuracy Test - Keysight Infiniium 9000 Series Service Manual

DC Gain Accuracy Test

When using the 50 Ω channel inputs, you must ensure that the input voltage to the
CAUTION
oscilloscope never exceeds ±5 V.
Let the oscilloscope warm up before testing
N OTE
The oscilloscope under test and other test equipment must be warmed up (with the
oscilloscope application running) for at least 30 minutes prior to the start of any performance
test.

50 Ω Input Impedance: Full scale is defined as 8 vertical divisions. Magnification is used below
10 mV/div. Below 10 mV full scale is defined as 80 mV. The major scale settings are 5 mV, 10 mV,
20 mV, 50 mV, 100 mV, 200 mV, 500 mV and 1 V.
1 MΩ Input Impedance: Full scale is defined as 8 vertical divisions. The major scale settings are
5 mV, 10 mV, 20 mV, 50 mV, 100 mV, 200 mV, 500 mV, 1 V, 2 V, and 5 V.
