Overview To take a TDR measurement (cont.)
Take automatic 16. Use the Vertical buttons to select the TDR waveform to
measurements
be measured.
17. Select one of the measurement tool bars.
18. Click the measurement you want (such as mean)
in the measurement tool bar.
19. Read the results in the measurements readout.
20. To take your measurement over a portion of the
waveform, select the Region tab to display the gate
controls. Click the check box as indicated at the right
to turn gating on and to display the gates on screen.
21. Use the G1 (Gate1) and G2 spin controls (or click and
type in values, use the keypad or multipurpose knobs,
or touch and drag the gate) to adjust the gates on
screen such that the area to measure is between the
gates.
If necessary to provide a good view of this portion of
the waveform, adjust the Vertical SCALE and
POSITION and the Horizontal SCALE, POSITION,
and Reference. To see the difference scale and
position can make in your waveform display, compare
the waveforms in Figure 15 and also compare the
waveforms in Figures 12 and 13.
