flexrio 5761 bandwidth

How can we adjust the Bandwidth of the Signal acquired using 5761R?

 

The Sampling rate is mentioned as 250 MS/s (Internal) and External to be between 175 MHz & 250 MHz.

 

As i understand, we have to keep a Bandpass Filter on the FPGA thorugh which we should be able to achieve this.

 

If we use the internal sample clock, we are achieving 50 MHz BW with 4 times DDC.

 

If we have to change the Bandwidth, what is the clock source to be used?

Hi Sundar,

 

You can refer to a example similar in which for NI 5641R we can define bandwidth.

 

You can find the example in NI Exmaple Finder named PXIe 5641R spectrum analyzer.

 

You can basically control the bandwidth by setting IQ rate for the hardware.
