Performance Verification
5.7 DC
Accuracy
Specification
≤
±
5 % of full scale at 2mV/div, with 0 mV offset.
≤
±
3 % of full scale at 5mV/div, with 0 mV offset.
≤
±
2 % of full scale at 10mV/div and above, with 0 mV offset.
Description
This test measures the DC Accuracy within the gain range specified.
It requires a DC source with a voltage range of 0 V to 20 V adjustable in steps of no
more than 15 mV, and a calibrated DMM that can measure voltage to 0.1 %.
Measurements are made using voltage values applied by the external
voltage reference source, measured by the DMM, and in the oscilloscope using the
parameters Std voltage.
For each known input voltage, the deviation is checked against the tolerance.
