Re: AD9361 56MHz RX bandwidth

Hi dpu,

 

As said in my previous post, IIO-Oscilloscope doesn’t appear to load the Tx FIR filter file (i.e. I cannot toggle the button that enables the TX FIR filter), even if it is designed with fstop<1/2 sample rate: I have the feeling that the issue concerns the loading of filter file and not the file content. As another not working example, find below screenshots of filter wizard and IIO-Oscilloscope for a 40 MHz bandwidth configuration (but the 40MHz bandwidth size must be certainly possible, as documented on AD9361 datasheet in regard to WiMAX 40 MHz).

We are interested in assessing whether AD9361 can be employed in a new product we are developing, so we decided to get the AD-FMCOMMS3-EBZ for evaluation purposes. Unfortunately the evaluation is taking much more time than expected because of the above mentioned issue, which is preventing us from understanding whether  AD9361 is the right choice for us.

 

To cut it short, being us interested in configuring both Rx and Tx FIR filters in FDD mode (as per my previous post dated 02 July), can you provide us with a working file with taps for Rx and Tx FIR filters, based on the filter wizard GUI inputs of the following screenshots?

Thank you in advance.
