Electrical Sampling Modules
1.
Set up the main instrument 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:
Set Acquisition Mode to
Average
,
16 samples
.
c.
In the Vert Setup dialog box:
Set Scale to
100 mV/div
.
Set Offset to
0 mV
.
d.
In the Meas Setup dialog box:
Select
Meas 1
and make sure the
Source1
button is selected.
Make sure the channel under test is selected in the Source tab, click
the
Pulse
Signal Type button, and then choose
Select Meas > Pulse –
Amplitude > Mean
.
2.
Set the power supply (Vin) =
–450 mV
.
3.
Record the DVM measurement in the
Input Vin
and the
x
columns as shown
in the following table.
4.
Read mean measurement and record it in the
Measured V, mV
and
y
columns
as shown in the following table.
5.
Repeat steps 2 to 3 for all other V
in
.
6.
Calculate S
x
, S
xx
, S
y
, and S
xy,
for each setting:
a.
Copy the
Input V
in
value to the
x
column.
b.
Copy the
Measured V, mV
value to the
y
column.
c.
Calculate x
2
and record in the
x
2
column.
d.
Calculate xy and record the value in the
xy
column.
e.
Add the up the
x. x
2
. y
and
xy
columns and record the sums in the
S
x
,
Sxx
,
S
y
and
S
xy
columns.
7.
Calculate a, b:
a.
a = (nS
xy
-S
x
S
y
) / (nS
xx
-S
x
^2)
b.
b = (S
xx
S
y
-S
xy
S
x
) / (nS
xx
-S
x
^2)
8.
Calculate y = ax+b for all x.
9.
Calculate the deviation of
Measured V – Y
for all x.
