IWR1443BOOST: Radar Studio: "ARM" and "Trigger Frame" buttons

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443

I'm performing some Radar Studio evaluation with the IWR1443 -> mmWave DevPack -> TSW1400 hardware chain and have gotten to the point where I am able to fully configure the system.  

However I have questions about the document here

.

Q1:It said that total period of data capture (=frame periodicity x No. of frames) < 10 seconds,what dose that mean?



I have collected some data successfully by using this setting in radar studio ,using one TX and four RX channels.I can get the data file, its size is 204800KB.


Different from the documentation, the total signal time here is 100 seconds（My frame periodicity is 1s and the number of frames is 100, giving a transmission time of 100s), well over 10 seconds. In operation, I first click "TSW1400 Arm" until the output interface displays "[RadarAPI]: TSW1400 capture complete" before clicking Trigger Frame, and then click "TSW1400 Arm" to save the data to the computer.

Q2: Is this correct? So I can not care about the total signal time, as long as the amount of data within 1GByte (TSW1400 storage ceiling) ?

    Answer: The time it takes to run every frame in the configuration is equal to <Number of Frames> X <Frame Periodicity>. = 100 Frames*1000 ms = 100 Seconds

    Answer: No. After you click TSW1400 Arm, the TSW will wait for the frames to start before capturing data. If frames do not start, eventually the TSW will time out and try to capture data anyways. This is why the output binary is the right size.  Proper procedure is to Click "TSW1400 Arm", wait 1 second for the Arming process to complete, then click "Trigger Frame". 

    Your total frame time is (100us + 120us) * 128 Chirps = 28.16 ms.  You can run 100 frames in just under 3 seconds, so there is no reason for your periodicity to be so large.
