input chip stream specifies the sequence of data chips to be despread.

spreading code specifies the sequence of bits that serve as the spreading code.

sync confidence threshold specifies the minimum correlation required for input chip stream to be considered synchronized with the spreading code. This parameter is only applicable when reset? is set to TRUE. Valid values are between 0.0 (no correlation required) and 1.0 (perfect correlation required).

sync search depth specifies the desired number of bits (not chips) over which to search for a sync confidence metric greater than the specified sync confidence threshold. This parameter is only applicable when reset? is set to TRUE.

reset? specifies whether the VI synchronizes despreading at each call using the sync search depth (bits) and sync confidence threshold parameters. reset? must be set to TRUE whenever you want to resynchronize. When reset? is set to FALSE, the sync search depth and sync confidence threshold parameters are ignored and despreading continues from the previous iteration. The default is TRUE.

error in (no error) can accept error information wired from previously called VIs. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	code identifies the error or warning code. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	source describes the origin of the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

output bit stream returns the despread series of bits.

Note   output bit stream has (1/L × input chip stream) number of elements, where L is the length of the spreading code sequence.

sync found index returns the synchronization index of the synchronization sequence found within the input chip stream. This parameter returns –1 if no sync was found.

sync confidence metric returns the measured confidence metric when input chip stream is aligned using the sync found index. Values fall between 0.0 (0% measured confidence) and 1.0 (100% measured confidence).

error out passes error or warning information out of a VI to be used by other VIs. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	code is the error or warning code. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
	source describes the origin of the error or warning. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
