16 Agilent 1000A Series Oscilloscopes Service Guide
To test DC gain accuracy
1 Disconnect all cables from the oscilloscope channel inputs.
2 Press the [Default Setup] front panel key.
3 Press the [Acquire] front panel key.
4 In the Acquire menu, press the Acquisition softkey until “Average”
appears.
5 Press the Averages softkey and turn the entry knob until “256”
appears.
CAUTION
Ensure that the input voltage to the oscilloscope never exceeds 300 Vrms.
Table 3 DC Gain Accuracy Specification
DC Gain Accuracy 2 mV/div to 5 mV/div: ±4.0% full scale
10 mV/div to 5 V/div: ±3.0% full scale
Full scale is defined as 8 vertical divisions. The major scale settings are 2 mV, 5 mV, 10 mV, 20 mV,
50 mV, 100 mV, 200 mV, 500 mV, 1 V, 2 V, and 5 V.
