Hello @ all
Sorry for the bad question!
I’m trying to create a simple block with GRC, but i don’t know how to do
this. I want to transmit noise on a specific frequency but only on a
range of ± 1MHz.
…
…
| noise source | |
| USRP2-Sink |
|---|
|Type: Gaussian | |Interpolation: 100 |
|Amplitude: 100m (0.1) | --------------> |Frequence: 929.8M |
|Seed: 42 | |Gain:
| 32dB |
|---|
But my result (shown with usrp_ffty.py) is: The noise is transmitted on
a wide range (± 40MHz), because i don’t know, how to limit the range
(and the Gain value doesn’t matter…).
I try to insert a “band pass filter” between noise source and USRP2-Sink
but with no results (what values are correct for low, high cut and
transition width?).
I hope someone can help me or give me a hint how to do this 
best regards
