[Discuss-gnuradio] USRP Power Supply Noise

[Jeffrey Lambert]

Hello,
I am attempting to build an analog front-end to a USRP 1 device.  I have 
selected a VCO that will suit the frequency range we are looking at: It 
is an RFVC1800 and has a tuning range of approximately 7.4 - 12.4 GHz 
over a 13 volt tuning voltage.  As this VCO is very sensitive to 
external noise, some power filtering will be necessary to minimize 
jitter and phase noise.  What I would like to know is whether or not 
there are any other adverse effects from using the simple switch mode 
supply that is included with the USRP?


Thanks,
