This function returns the value of the fiber interface error register when the AGE1439_STATUS_
FIBER_ERROR bit is set.
VXIplug&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.

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.
