Recovery delay and raw VDI calculation tempo

[gleb]

I noticed that Recovery delay probably affects a tempo of raw VDIs calculation.
While watching Spectragraph at 3freq and changing RD I see that RD period makes a delay during which new bars do not appear.
But they should!

As it was stated, RD is a duration of target's tone. But it seems to me that this setting is a little bit more complicated.

Please help!

I am sure that the Recovery Delay is tied in with the Ground Filter selection as well as the sweep speed. I like to "un-link" the Analysis screen which allows me to analyze a target using different filters, Recovery Delay, and sweep speeds.

RECOVERY DELAY
Once the R/D cycle is triggered, Spectra will give "selected R/D time" to the process, regardless of the number of targets in ground. If you give Spectra 100 R/D units, it will use every one. If your detector passes over one target, you must burn 100% of the R/D units before Spectra can process another target. Shorter R/D times can accommodate a denser target field. How long Spectra has to process the first target, and then be ready to process a second target. Lower numbers = SHORTER delay. Higher numbers = LONGER delay. Faster recovery doesn

Ah ha, I get it now clear as day. Very well put Rob. Thanks!

Very good explanation Rob, Thanks !

Thank you Rob!

But I mostly think about VDIs which build SpectraGraph (I called them raw VDIs). In 3freq/intensity/single sweep sometimes I see a rapidly changing chart. That indicates that new VDIs are arriving for each frequency. Changing filter speed and(or) RD seems to affect the speed of scanning and therefore affects tempo of new VDIs arrival.

During RD tone the Spectragraph freezes.

Do RD and filter affect the speed of scanning?

Thank you Rob!

That wouldn't be used except in prospecting.That indicates that new VDIs are arriving for each frequency. Changing filter speed and(or) RD seems to affect the speed of scanning and therefore affects tempo of new VDIs arrival.

English is not my native, sorry
I'll try to explain...
At a given sweep speed for this particular target machine can calculate and display on spectragraph different number of VDIs readings. It seems to me (maybe i'm wrong), that filtering and/or RD can affect the quantity of these readings.
In other words, spectragraph(in different modes) can be built of maybe 5(min) or 20(max) readings.

I captured spectragraph on video and watched it changing in slow motion. As it changes in realtime I can see how many changes (hows many VDIs) arrive during a sweep over this target.

Decreasing RD and setting a faster filter seem to produce more VDIs, so spectgraph seems more populated and more consistent.

Thank you for your patience, Rob!
Shame on me and my english...
