To verify DC vertical gain accuracy
This test verifies the accuracy of the analog channel DC vertical gain for each
channel.
In this test, you will measure the dc voltage output of a precision source using the
oscilloscope’s Average - Full Screen voltage measurement and compare the results
with the multimeter reading.
1 Press [Save/Recall] > Default/Erase > Factory Default to recall the factory default
setup.
Table 6 DC Vertical Gain Accuracy Test Limits
Models Test Limits Notes
6000 X-Series ±2.5% of full scale • Full scale is defined as 16 mV on the 1 mV/div range.
• Full scale on all other ranges is defined as 8 divisions
times the V/div setting.
