Both control panel and scopes show the various functions.

<https://www.skyradar.com/hs-fs/hubfs/Images/Blogs/control-panel-freescopes.jpg>They vary depending on the version and configuration which you purchased.

In the control panel, you can set functions and filter values.  
You can set:

- Suppress DC (eliminating the echo of the source)
- Reverse the signal (this reverses the signal, a feature that is sometimes needed in FFT)
- Set the [Sensitive Time Control (STC)](https://www.skyradar.com/blog/24-ghz-fmcw-radar-training-exercise-manual#h.gawvb6vobmd6)
- Activate the [MTI](https://www.skyradar.com/blog/topic/mti-mtd)
- Set and configure the [CFAR](https://www.skyradar.com/blog/topic/cfar) (static threshold can be set in the scopes directly)

 

In the choice box below the scopes you find the signal conversion chain:   
First you get Raw Data, then STC, then Suppress DC, then MTI, then CFAR.  
You can place for instance 5 A-scopes next to each other.

- The left one shows the Raw Data
- The second shows the Suppress DC (if you activated it  in the control panel)
- The third shows Suppress DC + STC (if you activated it in the control panel)
- The fourth shows  Suppress DC + STC + MTI
- The last one shows Suppress DC + STC + MTI + CFAR

So the student has the possibility to compare all stages in the signal conversion chain. It show what impact each of these functions / filters has.

Playing on the settings in the control panel makes the learning experience intense.
