Fall Time
Select, then set a value in dB. Delta markers are created and placed
at the Peak and at the specified value AFTER the Peak.
NOTE
Rise and Fall time in Marker Search uses different criteria than in Auto Analysis
and will therefore result in different reported values.
Auto Analysis
Auto Analysis reports the following TEN pulse measurements:
1
- Average Power
Average power level of all measured data points
2
- Peak Power
Highest reading of all measured data points
3
- Peak minus Average
Difference between the above two results
4
- Pulse Top
Power value based on the specified Pulse Top setting.
5
- Rise Time
The time it takes for a pulse to rise from 10% to 90% of its peak value.
6
- Fall Time
The time it takes for a pulse to fall from 90% to 10% of its peak value.
7
- Pulse Width
The time between the rising edge and falling edge of a pulse.
8
- Pulse Period
The time of one complete pulse cycle
9
- Duty Cycle
The ratio of the pulse width / pulse period.
10
- Pulse Rep Freq
The rate, in pulses / sec, at which pulses recur.
How to enable Auto Analysis
Press
Mrk ->/Tools
.
Then
Auto Analysis
Then choose from the following:
o
OFF
Analysis OFF
o
ON
The Analysis values appear below trace 1.
Pulse Top
Pulse Top is NOT the same as the pulse Peak. Pulse Top is used to set and report
the reference power level. You enter a value in percent, and the Pulse Top value
is reported in the Auto Analysis table in dB down from 100% of the reference
power level.
How to set Pulse Top
Press
Mrk ->/Tools
Then
Pulse Top
Then enter a percent value between 0 and 100 using the numeric keypad, the
▲|▼
arrows, or the rotary knob.
o
When set to 10%, 10 dB down from the 100% reference level is reported.
o
When set to 50%, 3 dB down from the 100% reference level is reported.
