Oscilloscope Performance Verification Tests
The performance verification tests described in this section verify the channel
measurement accuracy and acquisition system to provide confidence in
functionality and accuracy of the U1610/20A. These performance verification
tests are based on the U1610/20A specifications, as listed in the U1610/20A
User's Guide.
Voltage measurement accuracy verification test
This test verifies the accuracy of the analog channel voltage measurement for
each channel (DC vertical gain accuracy and dual cursor accuracy specifications).
In this test, you will measure the DC voltage output of an oscilloscope calibrator
using dual cursors on the U1610/20A.
Test limit:
±{4% of full scale* + 0.4% of full scale* (~1 LSB)}
*Full scale on all ranges is defined as 8 divisions multiplied by the V/div setting.
Refer to
accuracy verification test. Perform the following procedure for channel 1 and then
repeat the same procedure for channel 2.
