c.
In the Horz Setup dialog box:
H
set Record Length to 2000 points.
H
set Horizontal Reference to 50%.
H
set Scale to 500 ps/division, while using the horizontal position knob
to keep the falling edge centered.
d. In the Acq Setup dialog box:
H
set Acquisition Mode to Average, 128 samples.
H
under Stop After, check Condition and select Average Complete
from the pull down menu.
e.
In the Meas Setup dialog box:
H
make sure the channel under test is selected in the Source menu.
H
select Meas1, then choose Select Meas > Timing > Fall.
Follow this procedure to make the fall time checks:
1. Press the CLEAR DATA button on the CSA8000/TDS8000 front panel.
2. Press the RUN/STOP button on the CSA8000/TDS8000 front panel.
3. Check that the measured fall time (reflected rise time) is
35 ps, for the
positive edge polarity.
4. In the TDR Setup dialog box change C1 polarity to negative edge (pictured
as a falling slope).
NOTE
. Since this display is in units of rho (
r
), the waveform will not invert when
the edge polarity is changed, so the waveform will not appear to change
significantly.
5. Press the CLEAR DATA button.
6. Press the RUN/STOP button.
7. Check that the measured fall time (reflected rise time) is
35 ps, for the
negative edge polarity.
