Electrical Sampling Modules
Test
Follow this procedure to make the Vertical DC accuracy checks:
1.
Set the DC supply voltage to the settings listed based on the module being
tested. (See Table 2.)
2.
Push the
CLEAR DATA
button on the front panel.
3.
Push the
RUN/STOP
button on the front panel.
4.
Record the input voltage reading on the digital multimeter.
5.
Record the voltage for the Mean measurement displayed on the main
instrument screen.
6.
Calculate DC voltage accuracy:
error = input V – mean_meas V
.
7.
Verify that the error calculated in step 6 is within the limits listed in table for
the associated vertical scale and offset and DC voltage settings. (See Table 2.)
Enter the value on test record.
8.
Repeat steps 1 through 7 until all DC voltage and offset settings, listed in the
table, are checked for the channel under test. (See Table 2.)
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 are checked. (See Table 2.)
End of Procedure
Test
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 the following table, with the V
in
values plotted along the
x axis, and the measured values plotted along the Y axis.
