    We had recently procured FMCOMMS4 board for wide band applications. While testing it was observed that the till 4GHz center frequency the max hardware gain can be set as 71db and if i configure above 4GHz center frequency then max hard ware gain automatically it is changing to 62db.

why can't i configure 71db at above 4GHz center frequency?

 

 

 

We used IIO oscilloscope as the reference tried to set the gain of what i mentioned.

 

Here is the screen shot of settings panel with 4GHz center frequency  where you can find it as 71db max gain

 

screen shot of settings panel with 4.001GHz center frequency  where you can find it as 62db max gain

 

 

Please let us know if i have missed any thing in settings to set it to max hard ware gain
