Adjust Thresholds For Droop (Pulse)
Menu Path:
Rise Time (Lower & Upper), Fall Time (Lower & Upper), and Pulse Width threshold levels are specified as a percentage of the measured per pulse signal amplitude deviation. The signal amplitude deviation is defined to be the difference between the measured 100% Top Level and 0% Base Level in the user specified Amplitude Domain of either Voltage (Volt)or Power (Watt).
The reported Base Level (dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer) metric in the Pulse Table is used as the Rise Time 0% Base Level in the user specified Amplitude Domain.
When the Adjust Thresholds For Droop checkbox is disabled, the reported Top Level (dBm) value within the Pulse Table is used as the rising edge and falling edge 100% Top Level.
When the Adjust Thresholds For Droop checkbox is enabled, the reported Droop Start (dBm) and Droop Stop (dBm) values within the Pulse Table are used as the rising edge and falling edge 100% Top Levels.
Performance metric results affected include:
- Rise Time (s)
- Rise Edge (s)
- Fall Time (s)
- Fall Edge (s)
- Width (s)
-
Off Time (s)
- PRI (s)
- PRF pseudo-random function (s)
- Duty Cycle (%)
- On Level (dBm) (affected, but to a lesser extent)
- Peak Level (dBm) (affected, but to a lesser extent)
- Peak to Average (dB) (affected, but to a lesser extent)
