the average data between the detection of the Peak and the Neg Peak. It is
used for reducing VBW or irregular noise without using the trace average
function. This function indicates the averaged value with faster sweep speed.
▪ Neg Peak
When selected, the NPk is shown on the upper left side of the display.
The detection of the Neg Peak is used for searching for a similar signal below
the noise level. This accurately locates the negative peaks in the frequency. Use
the up/down keys to move between negative peaks.

You can turn markers ON or OFF by selecting a marker type and number. The marker is a diamond-

Normal
When a marker is not yet indicated, a single frequency marker on the currently
selected marker will be activated on the center frequency. When the marker is
already indicated, it becomes activated on a selected location. The marker number
is indicated on the marker. The indications on the activated function block and the
right of the display show the frequency and amplitude of a marker. If you press
Normal, the Delta function goes out, and the activated marker moves to the
location of the Delta marker.
