2.3.3.6
Read Out
Select a desired readout type for the X-axis for the marker. Different markers can use different readout
types. This setting will change the readout type and affect the marker readings in the active function
area and at the upper right corner of the screen, but will not change the actual value.
1.
Frequency
In this type, Normal marker shows the absolute frequency. Delta markers and Delta Pair markers show
the frequency difference between the delta marker and reference marker. The default readout mode in
non-zero span
is “
Frequency
”.
Note:
This type is invalid in Zero span.
2.
Period
In this type, the Normal marker shows the reciprocal of frequency; while Delta marker and Delta Pair
marker show the reciprocal of frequency difference. When the frequency difference is zero, the
reciprocal is infinite and 100 Ts is displayed.
Note:
This type is invalid in Zero span.
3.
Δ Time
In this type, the Normal marker shows the time difference between the marker and the start of the
sweep; while Delta marker and Delta Pair marker show the sweep time difference between the delta
marker and reference marker.
The default readout mode in Zero span
is Δ Time.
2.3.4 Peak
Open the peak search setting menu and execute peak search.
2.3.4.1
Peak -> CF
Execute peak search and set the center frequency of the analyzer to the frequency of the peak.
2.3.4.2
Next Peak
Search for and mark the peak whose amplitude is closest to that of the current peak and which meets
the peak search condition.
2.3.4.3
Next Left Peak
Search for and mark the nearest peak which is located at the left side of the current peak and meets the
peak search condition.
