R3267 Series Spectrum Analyzer Operation Manual (Vol.1)
3.3.25 UTIL Key (Utility)
3-80
Eye Opening OFF
Turns off the eye opening measurement function and artificial an-
alog display function simultneously. The split screens are also
turned off and the Utility menu is displayed.
Phase Noise
Displays the Phase Noise menu.
A menu used to measure phase noises and phase jitters is dis-
played.
C/N Meas
Displays the C/N Meas menu. A variety of settings for the phase
noise measurement can be performed. For this measurement, a
phase noise is calculated using an offset frequency which is devi-
ated from the carrier frequency or the current center frequency. A
maximum offset frequency of 10 points can be measured.
Edit Table
Displays the Edit Table menu, allowing you to set the desired off-
set frequency.
Insert
Enters the same data in the current cursor position.
Delete
Deletes the data at the current cursor position.
Table Init
Deletes all data from the table.
Signal Track ON/OFF
Toggles the signal track mode on or off.
ON:
The signal track mode is turned on, and measurements
are taken by keeping track of the carrier frequency,
which results in changes to the center frequency.
OFF:
Turns the signal track mode off.
Average Times ON/OFF
Toggles the trace averaging function on or off.
ON:
Sets the number of averaging times and traces and av-
erages the phase noise waveform for each offset fre-
quency.
OFF:
Turns the trace average function off.
C/N Meas OFF
The phase noise measurement function is turned off, and the
screen returns to the Phase Noise menu.
Phase Jitter
Displays the Phase Jitter menu. A variety of parameters used to
measure phase jitter can be set. A jitter is calculated by specifying
a phase noise integration range based on an offset frequency de-
viated from the carrier frequency that is the same as the current
center frequency.
