spwid	Int standing for spectral window id (0-based). The value must be >= 0.
	allowed:	int
	Default:	0

Returns
Quantity

Example

for spwid in range(at.getNumSpectralWindows()):
        numCh = at.getNumChan(spwid)
        print "Spectral window ", spwid, " has ", numCh, " frequency channels"
        for n in range(numCh):
                freq = at.getChanFreq(n, spwid)
                print "Channel ", n, " Frequency:", freq[’value’][0], freq[’unit’]
