Attached ZIP package includes various sample missions and a PDF documentation on how to properly use the Tx.

Please note that we have made changes to optimize the handling, so please use BUILD v2.2.0.11061 or higher from now on.

Have fun!

Hi Admin,

I have used the above zip to load the mission "DirectSignalGeneratorOneV6.rmix" and I am seeing Stream underflow and overflow. Spurs are observed in the standalone Spectrum Analyzer (KS).

I have attached the images and mission.

Decreasing the sample rate from 92.16 MHz to 1/16 of 92.16 MHz is just delaying the underflow.

Please help here to find out the problem.

Your RTSA software is too old.

Please update to the latest version which should be available within the next hours.

I have your MIL EE device and am trying to transmit the pre-stored IQ signal according to the instructions you provide. As soon as I start the Spectran V6 module, I have Tx yellow and the info "Imput underflows - stream source data rate to low and Input processing chain to slow". All this without playing the save file. I remind you that I have your compact device where this functionality was declared.

It is very hard to help you with such little information. Can you please at least show the mission and the block configs. Sure you use the "IQ Modulator" block, to bring V6 and source data into sync? But please provide more details, that should be an easy task then.

The yellow "Tx" is displayed after approx. 2 seconds after starting the Spectran V6 block even if there is no signal at the input.

Thanks for the help

You have to set the "Adapt Sample Rate" in the modulator. See my reproduction of your situation with full duplex. RX&TX:

The error remains despite the settings you recommended. It will be shown right after Tx is started, even before playback of stored data is started.

Might be a problem with your RTSA versin. We will have a new update release within this week which should fix it.
