age1439_fiber_error_get
This function returns the value of the fiber interface error register when the AGE1439_STATUS_
FIBER_ERROR bit is set.
VXIplug&play Syntax
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:
108
#include "age1439".h
ViStatus age1439_fiber_error_get(ViSession id, ViInt16 fiberErrorPtr);
Status Bit Definition
9 FI_ERR_UNLOCKED
8 TX_ERR_OVERRUN
7 RX_ERR_FIFO_OVERFLOW
6 RX_ERR_SYNC_LOST
5 RX_ERR_DISPARITY
4 RX_ERR_CODE_VIOLATION
3 RX_ERR_ALIGNMENT
2 RX_ERR_BEGIN_DISPARITY
1 RX_ERR_CRC
0 RX_ERR_SIGNAL LOST
Numeric
Value
512 Indicates that the internal receive or transmit
clock is not properly locked. This could be
caused by a poor quality receive signal.
256 Indicates that data transmission is not
sustainable because the raw data bandwidth
has exceeded the available fiber capacity.
128 Indicates that data arriving on the fiber receive
port has been lost.
64 Indicates that the receiver did not detect the
synchronization signal.
32 Indicates an invalid stream of bits was
detected in the received data.
16 Indicates an invalid stream of bits was
detected in the received data.
8 Indicates an invalid stream of bits was
detected in the received data.
4 Indicates an invalid stream of bits was
detected in the received data.
2 Indicates a cyclic redundancy check error has
occurred on the receiver of the fiber interface.
1 Indicates the signal is no longer being received
on the fiber interface.
