H Display the live waveform. Move the coupler from CH 3 to CH 4,
so that CH 1 and CH 4 are driven. (Use AUX1 and AUX2 instead of
CH3 and CH4 if your TDS model is so equipped). Press CH 4 to
display. See Figure 1–11 on page 1–51.
H Display the reference waveforms. To do this, press the front-panel
button MORE. Press the main-menu buttons Ref 2 and Ref 3. You
may notice their overlapping ground reference indicators. See
Figure 1–11 on page 1–51.
f. Measure the test signal:
H Locate the time reference points for these waveforms. Do this by
first identifying the point where the rising edge of the left-most
waveform crosses the center horizontal graticule line. Next, note the
corresponding time reference point for the right-most waveform. See
Figure 1–11 on page 1–51.
H Press CURSOR.
H Press the main-menu button Function; then press the side-menu
button V Bars.
H Press CLEAR MENU.
H Align one V bar cursor to the time reference point of the left-most
waveform edge and the other cursor to the time reference point of the
right-most waveform edge by rotating the General Purpose knob.
(Press SELECT to switch between the two cursors). See
Figure 1–11 on page 1–51.
H Read the measurement results at the D: cursor readout, not the @:
readout on screen.
