We present observations of PSRs J0437–4715 , J0738–4042 , J0835–4510 , J0908–4913 , J1048–5832 , J1622–4950 , J1644–4559 , J1721–3532 and J1740–3015 at 17 GHz using the Parkes radio telescope .
All 9 were detected at 17 GHz , additionally , we detected PSR J0835–4510 and J1622–4950 at 24 GHz .
Polarisation profiles of each pulsar and the variation with frequency are discussed .
In general , we find that the highly polarised edge components of young pulsars continue to dominate their profiles at 17 GHz .
Older pulsars ( \gtrsim 10 ^ { 5 } years ) appear to be almost completely depolarised .
Our detection of PSR J0437–4715 is the highest frequency observation of a millisecond pulsar to date , and implies a luminosity at 17 GHz of 14 \mu Jy kpc ^ { 2 } , and a mean spectral index of 2.2 .

We find that the spectral index of the magnetar PSR J1622–4950 is flat between 1.4 and 24 GHz , similar to the other known radio magnetars XTE J1810–197 and 1E 1547.0–5408 .
The profile is similar to that at 3.1 GHz , and is highly linearly polarised .
Analysis of the frequency evolution of the profile of PSR J0835–4510 show that the profile is made of four components that vary with frequency only in their amplitude .
The width and separation of the components remains fixed and the spectral index of each component can be determined independently .
