If you are using the Basic Rx daughterboard as your input, the RF transformer on it acts as a high pass filter. Try using an input signal > 100kHz. A megahetz would be even better. > Has anyone tried working with a square wave before > and faced this problem? Please let me know how to > correct this. Thanks The Basic USRP has a 50 Ohm input impedance. Will your circuit drive 50 ohms?
