API Functions | Signal Hound
bbDeviceNotOpenErr The device was unable to open. This can be returned for many reasons
such as the device is not physically connected, eight devices are already
open or there is an issue with the USB 3.0 connection.
bbUncalibratedDevice This message is returned as a warning and notes the device has not
been calibrated. If you see this warning, contact Signal Hound.
bbCloseDevice
Close one Signal Hound broadband device
bbStatus bbCloseDevice(int device);
Parameters
device Handle to the device being closed.
Description
This function is called when you wish to terminate a connection with a device. Any resources the device
has allocated will be freed and the USB 3.0 connection to the device is terminated. The device closed
will be released and will become available to be opened again.
Return Values
bbNoError The device closed successfully.
bbDeviceNotOpenErr The device specified is not open.
bbConfigureAcquisition
Change the detector type and choose between linear or log scaled returned sweeps
bbStatus bbConfigureAcquisition(int device, unsigned int detectorType, unsigned int
verticalScale);
Parameters
device Handle to the device being configured.
detectorType Specifies the video detector. The two possible values for detector type
are BB_AVERAGE and BB_MIN_AND_MAX.
verticalScale Specifies the scale in which sweep results are returned int. The four
possible values for verticalScale are BB_LOG_SCALE, BB_LIN_SCALE,
BB_LOG_FULL_SCALE, and BB_LIN_FULL_SCALE.
Description
detectorType specifies how to produce the results of the signal processing for the final sweep.
Depending on settings, potentially many overlapping FFTs will be performed on the input time domain
data to retrieve a more consistent and accurate final result. When the results overlap detectorType
chooses whether to average the results together, or maintain the minimum and maximum values. If
averaging is chosen, the min and max trace arrays returned from bbFetchTrace() will contain the same
averaged data.
