An Example Of Scrolling - HP 3563A Operating Manual

An Example of Scrolling

Figure 8-8a shows a measurement made at 0 - 100 kHz. A 10 kHz wide X marker band was created
using HOLD X CENTER; the band is shown from 45 to 55 kHz in figure 8-8b. Figure 8-& shows this
10 kHz band magnified using X MRKR SCALE. Finally, SCROLL ON OFF was toggled ON, then the
�
100 kHz trace was viewed, 10 kHz at a time, using the knob in the Marker group. Figure
entire
8-8d shows the trace scrolled through 5 to 15 kHz. Note that scrolling follows the time or frequency
axis in displays with more than two axes.
