Best settings for impulsive wide-band 6m RFI hunting

 

Hi. What are the best setting to quickly hunt an impulsive wide-band noise in 6m band? My current settings in my TinySA Ultra:
?
-FREQUENCY: 49 - 55 MHz (a little more of the detected noise)
-SWEEP POINTS: 290 point
-SWEEP ACCURACY: FAST
-WSPEEDUP: 2
-CONFIG - SPUR REMOVAL: OFF
?
I have the following problems:
?
1) I'd need a faster scan in order to locate the noise source with my portable loop.
?
2) when I use the command? STORAGE - SAVE CAPTURE, I hardly can capture well the yellow impulsive noise, as it changes very quickly . This was a very lucky shot.
?
Any suggestions will be appreciated.
?
Many thanks

Trace -> Calc Off -> Max Hold

This is how you capture quick pulses. Max Hold captures the highest peak and continues to display it until a new higher peak is detected. You can refresh it by turning it off and then back on again.?

Max Decay does the same thing but it gradually decays over time until a new higher peak is detected.?

Display -> Sweep Time -> 1000 ms

You can also try a longer sweep time.?

And... use the widest bandwidth that allows sufficient S/N.
