Function Generator and Arbitrary Waveform Generator modes.

Returns the reference clock source.

GtWaveGetReferenceClockSource (nHandle, pnSource, pnStatus)

Name	Type	Comments
nHandle	SHORT	Handle to a GX11X0 board.
nChannel	SHORT	Specified Channel number. GX1120: 0 = GTWAVE_CHANNEL_A: Channel A. GX1120: 0 = GTWAVE_CHANNEL_A: Channel A. 1 = GTWAVE_CHANNEL_B: Channel B.
pnSource	PSHORT	Reference clock source are: 0. GTWAVE_REF_CLOCK_SOURCE_INTERNAL: Reference clock source is the internal 10MHz clock 1. GTWAVE_REF_CLOCK_SOURCE_EXTERNAL: Reference clock source is the external clock 2. GTWAVE_REF_CLOCK_SOURCE_PXI10MHZ Reference clock source is the PXI backplan 10MHz clock
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.
