Check that the vertical position is set to 0 divs as 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
0 divs
.
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
Termination
to
50
Ω
.
9.
Set the vertical
Scale
to
1 mV
per 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
shown in the test record.
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 record.
14.
Repeat the tests at 1 M
Ω
impedance as follows:
a.
Change the calibrator impedance to 1 M
Ω
.
b.
Push the front-panel channel 1 button.
