5-26 Performance Verification WR6K Rev. D
1) Verify that the displayed trace A : Average (1) is on the screen, near the center
horizontal graticule line. If the trace is not visible, modify the DC voltage
reference source output until the trace is within ± 2 divisions of center.
2) Connect the DMM and record the voltage reading in Table 9, column DMM.
3) Disconnect the DMM from the BNC T connector.
4) Press Clear Sweeps
5) After 100 sweeps, Read off the DSO Mean parameter voltage, and record the
measurement in Table 9, column Mean.
Repeat the test for the other channels, substituting channel controls and input
connector. Record the measurements in Table 9.
Calculate the Difference ( ∆ ) by subtracting the DMM voltage reading from the
DSO mean voltage reading.
Record the test result in Table 9, and compare the Difference ( ∆ ) to the
corresponding limit in the test record.
