Oscilloscope Performance Verification Tests
The performance tests verify the channel’s measurement accuracy and
acquisition system to provide confidence in functionality and accuracy of
the instrument. The performance verification tests are based on the
instrument’s specification as listed in “Chapter 9 Specification and
Characteristic”.
Voltage Measurement Accuracy Verification Test
This test verifies the voltage measurement accuracy. In this test, you will
measure the output of a power supply using dual cursors of the
instrument and compare the results with reading from the multimeter.
Test limits: 50 mV/div to 100 V/div
±
3% of full scale *
5 mV/div to 20 mV/div
±
5% of full scale *
* Full scale on all ranges is defined as 8 divisions multiplied by the
V/div setting.
Refer to Table 7- 1 for the equipment required for this voltage
measurement accuracy verification test. Perform the following procedures
for channel 1, then repeat the same procedure for channel 2.
