[spectrum,qual] = MeasSpd([S],[meterType],[syncMode])

This routine splines the raw return values from the
meter to the wavelength sampling S. The splining
handles conversion of power units according to
to the wavelength sampling delta. If S is not passed,
it is set to [380 5 81].

Tries to handle low light level case gracefully by returning
zero as the answer.

meterType == 1: PR650 (default)
meterType == 4: PR655
meterType == 5: PR670
meterType == 6: PR705

syncMode = ‘on’: Try to sync integration time with display, if meter supports it (default)
syncMode = ‘off’: Don’t try to sync, even if meter supports it.
