Detailed Description

By default the highest available range is selected and auto ranging is enabled.

Function Documentation

bool8_t ScpChGetAutoRanging	(	TpDeviceHandle_t	hDevice,
		uint16_t	wCh
	)

Check whether auto ranging is enabled.

Parameters

hDevice	A device handle.
wCh	Channel number, 0 to ScpGetChannelCount() - 1.

Returns

BOOL8_TRUE if enabled, BOOL8_FALSE if disabled.

bool8_t ScpChSetAutoRanging	(	TpDeviceHandle_t	hDevice,
		uint16_t	wCh,
		bool8_t	bEnable
	)

Set auto ranging.

Parameters

hDevice	A device handle.
wCh	Channel number, 0 to ScpGetChannelCount() - 1.
bEnable	BOOL8_TRUE to enable or BOOL8_FALSE to disable.

Returns

BOOL8_TRUE if enabled, BOOL8_FALSE if disabled.

uint32_t ScpChGetRanges	(	TpDeviceHandle_t	hDevice,
		uint16_t	wCh,
		double *	pList,
		uint32_t	dwLength
	)

Get supported ranges for current coupling.

Example:

uint32_t dwRangeCount = ScpChGetRanges( hDevice , wCh , NULL , 0 );
double* pRanges = malloc( sizeof( double ) * dwRangeCount );
dwRangeCount = ScpChGetRanges( hDevice , wCh , pRanges , dwRangeCount );

printf( "ScpChGetRanges (Ch%u):\n" , wCh + 1 );
for( i = 0 ; i < dwRangeCount ; i++ )
  printf( "- %f\n" , pRanges[ i ] );

free( pRanges );

Parameters

hDevice	A device handle.
wCh	Channel number, 0 to ScpGetChannelCount() - 1.
pList	Pointer to array.
dwLength	Number of elements in array.

Returns

Total number of ranges.

double ScpChGetRange	(	TpDeviceHandle_t	hDevice,
		uint16_t	wCh
	)

Get range.

Parameters

hDevice	A device handle.
wCh	Channel number, 0 to ScpGetChannelCount() - 1.

Returns

Range.

double ScpChSetRange	(	TpDeviceHandle_t	hDevice,
		uint16_t	wCh,
		double	dRange
	)

Set range.

Example:

double dRange = 10;

dRange = ScpChSetRange( hDevice , wCh , dRange );

printf( "ScpChSetRange = %f" , dRange );

Note

Setting the range doesn't disable auto ranging.

Parameters

hDevice	A device handle.
wCh	Channel number, 0 to ScpGetChannelCount() - 1.
dRange	Maximum value that must fit within range.

Returns

Range.
