allows the user to adjust the frequency of the tracking-generator oscillator
manually using the step keys or knob. The tracking adjust is tuned to maximize
the amplitude of the trace.
Tracking error occurs when the output frequency of the tracking generator is
not exactly matched to the input frequency of the spectrum analyzer. The
resulting mixing product from the spectrum analyzer input mixer is not at the
center of the IF bandwidth. Any tracking errors may be compensated for
through manual adjustments of the tracking generator’s oscillator, or through
an automatic tracking routine, which is initiated by pressing TRACKING PEAK .

activates a second marker at the position of the first marker. (If no marker is
present, two markers appear at the center of the display.) The amplitude and
frequency of the first marker is fixed, and the second marker is under your
control. Annotation in the active function block and in the upper-right corner
of the screen indicates the frequency and amplitude differences between the
two markers. The display mode must not be changed between log and linear
while using a delta marker.
Note
If there are already four markers when MARKER A is pressed, a nonactive
marker disappears, the active marker becomes a reference marker, and the
delta marker becomes the active marker.
