  Rotating Radio Transients (RRATs) are a relatively new subclass of pulsars
that emit detectable radio bursts sporadically. We conducted an analysis of 10
RRATs observed using the Parkes telescope, with 8 of these observed via the
Ultra-Wideband Receiver. We measured the burst rate and produced integrated
profiles spanning multiple frequency bands for 3 RRATs. We also conducted a
spectral analysis on both integrated pulses and individual pulses of 3 RRATs.
All of their integrated pulses follow a simple power law, consistent with the
known range of pulsar spectral indices. Their average spectral indices of
single pulses are -0.9, -1.2, and -1.0 respectively, which are within the known
range of pulsar spectral indices. Additionally, we find that the spreads of
single-pulse spectral indices for these RRATs (ranging from -3.5 to +0.5) are
narrower compared to what has been observed in other RRATs (Shapiro-Albert et
al. 2018; Xie et al. 2022). It is notable that the average spectral index and
scatter of single pulses are both relatively small. For the remaining 5 RRATs
observed at the UWL receiver, we also provided the upper limits on fluence and
flux density. In addition, we obtained the timing solution of PSR J1709-43. Our
analysis shows that PSRs J1919+1745, J1709-43 and J1649-4653 are potentially
nulling pulsars or weak pulsars with sparse strong pulses.
