Nowadays, most of communication systems are well
suited for the evolving technology of Software-Defined Radios
(SDR). Despite the wide variety of SDR applications, one trait is
common among them which is the frequency hopping. Systems
utilizing frequency hopping with high hopping rates have strong
limitations on the frequency tuning time. In this paper, we assess
the influences of several tuning options, offered by the GNU
Radio Universal Hardware Driver (UHD), with respect to tuning
time. Our target SDR platform is the Universal Software Radio
Peripheral (USRP)-N210, the highest performing class among
the USRP family, paired with the RFX2400 daughterboard. Our
aim is to figure out the tuning option that results in minimum
tuning time allowing the realization of faster hopping rates.
