age1439_fiber_error_get
This function returns the value of the fiber interface error register when the AGE1439_STATUS_
FIBER_ERROR bit is set.
VXI plug&play Syntax
#include "age1439".h
ViStatus age1439_fiber_error_get(ViSession id, ViInt16 fiberErrorPtr );
Description
age1439_fiber_error_get returns the fiber interface errors.
Parameter
id is the VXI instrument session pointer returned by the age1439_init function.
fiberErrorPtr points to the value of the fiber interface error. The bits are defined below:
Status Bit Definition
Numeric
Value
Description
9 FI_ERR_UNLOCKED 512 Indicates that the internal receive or transmit
clock is not properly locked. This could be
caused by a poor quality receive signal.
8 TX_ERR_OVERRUN 256 Indicates that data transmission is not
sustainable because the raw data bandwidth
has exceeded the available fiber capacity.
7 RX_ERR_FIFO_OVERFLOW 128 Indicates that data arriving on the fiber receive
port has been lost.
6 RX_ERR_SYNC_LOST 64 Indicates that the receiver did not detect the
synchronization signal.
5 RX_ERR_DISPARITY 32 Indicates an invalid stream of bits was
detected in the received data.
4 RX_ERR_CODE_VIOLATION 16 Indicates an invalid stream of bits was
detected in the received data.
3 RX_ERR_ALIGNMENT 8 Indicates an invalid stream of bits was
detected in the received data.
2 RX_ERR_BEGIN_DISPARITY 4 Indicates an invalid stream of bits was
detected in the received data.
1 RX_ERR_CRC 2 Indicates a cyclic redundancy check error has
occurred on the receiver of the fiber interface.
0 RX_ERR_SIGNAL LOST 1 Indicates the signal is no longer being received
on the fiber interface.
