Electrical Sampling Modules
3.
Check aberrations in the range of 150 ps to 400 ps after the edge (aberrations
12% to –2%).
a.
Set Meas1 and Meas2 as follows:
Meas1
: Select the
Region
tab and set
G1
to
40%
(150 ps) and
G2
to
90%
(400 ps).
Meas2
: Select the
Region
tab and set
G1
to
40%
(150 ps) and
G2
to
90%
(400 ps).
b.
Check that the TDR incident edge aberrations in the range of 150 ps to
400 ps after the edge are within speci
fi
cation:
Aberration Upper Spec limit (USL): Meas1 +Overshoot(C1)
≤
+12%.
Aberration Lower Spec limit (LSL): Meas4 Mean(M1)
≥
–2%.
4.
Check aberrations in the range of 400 ps to 5 ns after the edge (aberrations
within ±2%).
a.
Change the time/div to
1 ns/div
using the Horizontal Scale knob.
b.
Set Meas1 and Meas2 as follows:
Meas1
: Select the
Region
tab and set
G1
to
14%
(400 ps) and
G2
to
60%
(5 ns).
Meas2
: Select the
Region
tab and set
G1
to
14%
(400 ps) and
G2
to
60%
(5 ns).
c.
Check that the TDR incident edge aberrations in the range of 400 ps to
5 ns after the edge are within speci
fi
cation:
Aberration Upper Spec limit (USL): Meas1 +Overshoot(C1)
≤
+2%.
Aberration Lower Spec limit (LSL): Meas4 Mean(M1)
≥
–2%.
5.
Check aberrations in the range of 5 ns to 100 ns after the edge (aberrations
1% and –2%).
a.
Change the time/div to
20 ns/div
using the Horizontal Scale knob.
b.
Push the front panel
FINE
button to turn it on.
c.
Adjust the position such that the incident edge 50% crossing occurs at
the left edge of the screen.
d.
Push the front panel
FINE
button to turn it off.
e.
In the Horizontal Setup dialog box, set Horizontal Reference to
0%
