If a single marker is already on, MARKER DELTA
places both an anchor marker and an active (movable)
marker at the position of the original, single marker. To
move the active marker, use either the knob, the step
keys, or the data keys. If two markers are already on,
pressing MARKER DELTA once makes it the active
function. However, if MARKER DELTA is already the
active function, pressing MARKER DELTA places the
anchor marker at the same position as the active
marker. The delta amplitude is displayed in dB, or as a
ratio when linear units are selected.

PEAK SEARCH
Activates a single marker and places it at the center
MARKER NORMAL
of the trace. This softkey location is changed to the
MARKER DELTA function, if delta-marker mode has
been previously activated by the MARKER DELTA
softkey under the
If one marker is already on, no operation takes place. If
two markers are on (as in MARKER DELTA mode),
MARKER NORMAL deletes the anchor marker and
makes the active one the new, single marker. The
marker reads the amplitude and the frequency (or the
relative time, when the frequency span equals 0 Hz),
and displays these values in the active function block
and in the upper-right corner of the display. To move
the marker, use either the knob, the step keys, or the
data keys.
The marker reads data from the currently active trace.
(An active trace is one in either the clear-write or
max-hold mode; this may be either trace A or trace B.)
If both traces are active, or if both traces are in view
mode, the marker reads data from trace A.
Front-panel key access:

MKR
Turns off all markers, blanks the softkey menu, and
MARKERS OFF
expands the display screen. This softkey turns off all
marker-related functions such as SIG TRK ON OFF
and MKRNOISE ON OFF, if they are on.
Front-panel key access:
Displays and holds the maximum responses of the
MAX HOLD A
input signal in trace A. In this mode, the trace accepts
data from subsequent sweeps and selects the
positive-peak detector mode.
