Electrical Sampling Modules
Test
Follow this procedure to make the input impedance check:
1.
Set the digital multimeter (DMM) to measure
Ohms
.
2.
Record the resistance reading (InputR).
3.
Swap the test leads at the DMM and again record the resistance reading
(reverseInputR).
4.
Check average of
InputR
and
reverse-InputR:
80E01, 80E02, 80E03, 80E04, 80E06:
≤
50.5
Ω
and
≥
49.5
Ω
80E07B, 80E08B, 80E09B, 80E10B:
≤
51
Ω
and
≥
49
Ω
5.
80E04 Only:
Set the Digital multimeter to measure
Volts
at the minimum
range (
≤
100 mV
).
6.
80E04 Only:
Record reading on the Digital multimeter as baseline voltage.
7.
80E04 Only:
Check baseline voltage for
≤
±1 mV
. Enter value on test record.
8.
Make the following settings, and then repeat steps 1 through 7 to check
channel 2.
a.
Select the next channel to test (if any) from the Waveform Selector menu
on the controls bar at the bottom of the display (left corner).
b.
In the Vert Setup dialog box, set Offset to
0.0 V
.
9.
Disconnect the test setup.
