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
†
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. 
1 Set up the instrument.
• Set the Volts/div to the value stated in the first line in Table 7- 3.
* Dual Y-Cursor Measurement instructions can be found on page 71.
† Full scale on all ranges is defined as 8 divisions multiplied by the V/div setting.
