TABLE
ADL NRM
switches the marker table between the normal marker formats and the delta
display line format. The marker information can be displayed in absolute
amplitude and frequency. It can also be displayed in delta amplitude and
frequency using one marker as the reference. These are normal marker modes.
Press the TABLE ADL NRM softkey to underline the ADL. This accesses the
delta display line format, which is only available when using the marker table
function. This format displays the marker amplitudes relative to the display
line.

THRESHLD
ON OFF
sets a lower boundary to the active trace. The threshold line “clips” signals
that appear below the line when this function is on. The boundary is defined
in amplitude units that correspond to its vertical position when compared to
the reference level.
Time
accesses the softkey menu used to set and display the real-time clock.

The value of the threshold appears in the active-function block and on the
lower-left side of the screen. The threshold level does not influence the trace
memory or marker position. The peaks found by the markers must be at least
the peak-excursion value above the threshold level. The value of the threshold
level can be changed using the step keys, the knob, or the numeric keypad.
Pressing any digit, 0 through 9, on the numeric keypad brings up the selected
terminator menu. If a threshold is active, press THRESHLD ON OFF until OFF
is selected to turn the threshold display off. The threshold value affects peak
searching even when the THRESHLD function is set to off.
