Summary (Advanced Radar)
Menu Path:
This trace is only available when the Synchronization Domain is Amplitude or the Pulsed checkbox is checked. If both of these are not true, the trace won't be available for selection.
The Summary table displays the following metrics for the current acquisition:
- Pulses
- Average Power
- Peak Power
- Detection Threshold
- Top Level
- Base Level
- Top/Base
- Time Offset
When averaging is turned on, the reported metrics are averaged.
Pulses
Pulses reports the number of valid pulses detected within user specified Acquisition Length (s) time interval up to the user specified Maximum Pulse Count value.
Valid pulses will depend on which measured pulses meet the user specified valid Pulse Detection criteria as determined by the following properties:
- Pulse Detection – Reference
- Pulse Detection – Threshold (dB or dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer)
- Pulse Detection – Hysteresis (dB)
- Pulse Detection – Ignore Dropouts (s)
- Pulse Detection – Min Pulse Width (s)
- Pulse Detection – Max Pulse Width (s)
Avg Power
Avg Power reports the average power in dBm measured over the entire Acquisition Length (sec).
Peak Power
Peak Power reports the peak power in dBm measured over the entire Acquisition Length (sec).
Detection Thresh
Detection Threshold reports the currently used absolute Pulse Detection Threshold (dBm) level determined by the following user specified properties:
- Pulse Detection – Reference
- Pulse Detection – Threshold (dB or dBm)
The Pulse Detection Threshold (dBm) level is used to detect which measured pulse signal amplitude rising edge level transitions will be considered as valid pulse-on transitions for inclusion within pulse analysis results.
The measured signal will only be considered to contain a valid pulse-off transition if the amplitude subsequently decreases below the Pulse Detection Threshold (dBm) – Hysteresis (dB) offset level.
Top Level
Top Level reports the measured 100% Top Level in dBm measured over the entire Acquisition Length (sec).
Detailed definition of supported Top Level measurement methods can be found under the Top/Base Calculation Method property descriptions.
Base Level
Base Level reports the measured 0% Base Level in dBm measured over the entire Acquisition Length (sec).
Detailed definition of supported Base Level measurement methods can be found under the Top/Base Calculation Method property descriptions.
Top/Base
Top/Base reports the dB ratio value of Top Level over Base Level measured over the entire Acquisition Length (sec). (i.e. equates to Top Level (dBm) - Base Level (dBm))
Detailed definition of supported Top Level and Base Level measurement methods can be found under the Top/Base Calculation Method property descriptions.
Time Offset
Time Offset reports the time offset in value in seconds, from acquisition trigger event occurrence to the start of first valid detected pulse within Acquisition Length (sec) (i.e. where first valid detected LFM region is reported as Pulse 1 within Pulse Table).
