Performance Verification
7. Check that the v
ertical position is set to 0 divs a s follows:
a. Push the lower-bezel More button to select Position.
b. In the side-bezel button, check that the Vertical Position is set to 0divs.
c. If it is not 0 divs, turn the Vertical Position knob to set the position to 0.
8. If you are testing a < 1 GHz model (DPO4014B, DPO4034B or DPO4054B),
go to step 14. Otherwise, select the 50 Ω impedance as follows:
a. Set the calibrator to 50 Ω output impedance (50 Ω source impedance).
b. Push the channel 1 button.
c. Set the Te
rmination to 50 Ω.
9. Set the vertical Scale to 1mVper division.
10. Set the offset as follows:
a. Set the calibrator to 900 mV vertical offset.
b. Push the lower-bezel More button to select Offset.
c. Use the Multipurpose a knob to set the Vertical Offset to 900 mV,as
showninthetestrecord.
11. Select the Mean measurement (if not already selected) as follows :
a. Push
the front-panel Wave Inspector Measure button.
b. Push the Add Measurement lower-bezel button.
c. Use the Multipurpose b knob to select the Mean measurement.
d. Push the OK Add Measurement side-bezel button.
12. View the mean value in the measurement pane at the bottom of the display
and enter it as the test result in the test record.
13. Repeat step 12 for each vertical scale and offset setting combination shown
in the test re cord.
14. Repeat the tests at 1 MΩ impedance as follows:
a. Change the calibrator impedance to 1 MΩ
.
b. Push the front-panel channel 1 button.
