6. Calculate DC voltage accuracy: error = input V – meas V.
7. CHECK that the error calculated in step 6 is within the limits listed
Table 4–2 for the associated vertical scale and offset and DC voltage
settings. Enter the value on test record.
8. Repeat steps 1 through 7 until all DC voltage and offset settings, listed in
Table 4–2, are checked for the channel under test.
9. Change all settings in the setup to Channel 2, and then repeat steps 1 through
7 until all DC voltage settings and offset settings, listed in Table 4–2, are
checked.
End of Procedure
Follow this procedure to make the DC vertical voltage accuracy, single point,
compensated checks:
The gain of the 80E00 is equal to the slope of a regression line of the paired
measurement readings in Table 4–3, with the V
in
values plotted along the x axis,
and the measured values plotted along the Y axis.

1. Set up the CSA8000/TDS8000 as follows:
a. Select C1 from the Waveform Selector menu on the controls bar at the
bottom of the display (left corner).
b. In the Acq Setup dialog box:
H
set Acquisition Mode to Average, 16 samples.
c.
In the Vert Setup dialog box:
H
set Scale to 100 mV/division.
H
set Offset to 0 mV.
