Testing Performance

To verify voltage measurement accuracy

This test verifies the voltage measurement accuracy. In this test, you will

measure the output of a power supply using dual cursors on the oscilloscope,

and compare the results with the multimeter reading.

Test limits: ±2.0% of full scale ±1 LSB*

• 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.

*1 LSB = 0.4% of full scale

Equipment Required to Verify Voltage Measurement Accuracy

Do this procedure first for Channel 1. Then repeat the procedure for Channel 2.

Set up the oscilloscope.

a Adjust the channel 1 position knob to place the baseline at approximately

0.5 division from the bottom of the display.
