5-14 Performance Verification Rev. D
This test measures the DC Accuracy of the absolute voltage measurements at 0V
offset setting. 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.
Specification & Test limits
±
(0.015 x | Vm + Voffset | + 0.015 x | Voffset| + 0.01 x FS + 1mV)
Vm
[volts] = voltage reading [volts]
FS [volts] = 8[div] x sensitivity [volt/div]
Voffset [volts] = setting offset voltage [volts]
