LibTiePie  0.7.4
Library for interfacing TiePie engineering instruments

Description

Functions to control the input bandwidth of an oscilloscope channel.

By default the input bandwidth of a channel is set to the highest value available.

Function Documentation

uint32_t ScpChGetBandwidths ( LibTiePieHandle_t  hDevice,
uint16_t  wCh,
double *  pList,
uint32_t  dwLength 
)

Get the supported input bandwidths for a specified channel.

Parameters
[in]hDeviceA device handle identifying the oscilloscope.
[in]wChThe channel number identifying the channel, 0 to ScpGetChannelCount() - 1.
[out]pListA pointer to an array for the input bandwidths.
[in]dwLengthThe number of elements in the array.
Returns
The total number of bandwidths.
Status values
UNSUCCESSFUL An error occurred during execution of the last called function.
INVALID_CHANNEL The requested channel number is invalid.
INVALID_HANDLE The handle is not a valid oscilloscope handle.
OBJECT_GONE The object indicated by the handle is no longer available.
LIBRARY_NOT_INITIALIZEDThe library is not initialized, see LibInit().
SUCCESS The function executed successfully.
