uint32_t ScpChGetConnectorType	(	TpDeviceHandle_t	hDevice,
		uint16_t	wCh
	)

Get the channel connector type.

Parameters

hDevice	A device handle identifying the oscilloscope.
wCh	The channel number identifying the channel, `0` to `ScpGetChannelCount() - 1`.

Status values

NOT_SUPPORTED	The channel does not support reading the connector type.
INVALID_CHANNEL	The requested channel number is not valid.
INVALID_HANDLE	The handle is not a valid oscilloscope handle.
DEVICE_GONE	The device indicated by the device handle is no longer available.
SUCCESS	The function executed successfully.

Check whether the channel has a differential input.

Parameters

hDevice	A device handle identifying the oscilloscope.
wCh	The channel number identifying the channel, `0` to `ScpGetChannelCount() - 1`.

Status values

INVALID_CHANNEL	The requested channel number is not valid.
INVALID_HANDLE	The handle is not a valid oscilloscope handle.
DEVICE_GONE	The device indicated by the device handle is no longer available.
SUCCESS	The function executed successfully.

Get the channel input impedance.

Parameters

hDevice	A device handle identifying the oscilloscope.
wCh	The channel number identifying the channel, `0` to `ScpGetChannelCount() - 1`.

Status values

NOT_SUPPORTED	The channel does not support reading the input impedance.
INVALID_CHANNEL	The requested channel number is not valid.
INVALID_HANDLE	The handle is not a valid oscilloscope handle.
DEVICE_GONE	The device indicated by the device handle is no longer available.
SUCCESS	The function executed successfully.
