Key Reference 4

N9320A Spectrum Analyzer 107

Min Search Moves the active marker to the minimum detected amplitude.

Key access:

Pk-Pk Search Finds and displays the frequency (or time, if in zero span),

and amplitude differences between the highest and lowest

trace points.

Key access:

Continuous Pk

On Off

When Continuous Pk is on, the marker will remain on the peak

signal even if the frequency of that signal changes. The

marker will remain on that signal as long as the amplitude

of the signal does not change by more than 3 dB from one

sweep to another.

If the signal is lost, the marker will attempt to find it again

and maintain on the peak. If there are other signals on

screen near the same amplitude, one of them may be found

instead. Signals near 0 Hz cannot be maintained effectively.

This function is intended to maintain the marker on signals

with a frequency that is changing, and an amplitude that is

not changing.

N dB Points

On Off

Activates the N dB function. Pressing N dB Points (On)

activates two arrows that are N dB down from the marker.

The frequency difference between the two arrows will be

displayed in the upper right- hand corner of the display.
