Hi, What is the maximum output power from the LFTX daughterboard when used with the USRP N200?
According to this datasheet [1], the N200 with the WBX daughterbaord provide an output power of 15 dBm. However, when using the LFTX daughterboard, I am getting a much less output power. [1] http://www.ettus.com/content/files/07495_Ettus_N200-210_DS_Flyer_HR.pdf In GNU Radio with the USRP N200, we use a sinusoid with a frequency of 150 kHz and an amplitude of 0.98, fed into the LFTX daughterboard for a center frequency of 5 MHz. When the output of LFTX is plugged into a scope terminated with a 50-ohm terminator, the scope reads 24.8 mV (peak-to-peak). This is around -28.13 dBm. Is this the max power one can get out of the LFTX daughterboard? Thanks. Best regards, Khalid
