Setting up Generator 5
You have the following options for inserting FEC errors into the output data
stream:
• State - Enables/disables the continuous FEC error insertion. The
inserted errors are after the FEC encoding.
• Errors per Frame - Specifies the number of symbols to be corrupted
within a single FEC frame. The inserted errors are at random symbol
positions. Each corrupted symbol will contain exactly one bit error at a
random bit position.
• Insert Single BIP Error - Insert a single Bit Interleaved Parirty (BIP)
error. This is a pre-FEC error and can be inserted at any time, even if the
FEF error insertion is disabled.
FEC Remote Programming
The following SCPI commands can be used for FEC error insertion remote
programming:
1 Commands for selecting FEC patterns:
:DATA:SEQuence:SET
'M1.DataOut1',Memory,'factory:FEC/IEEE_802_3cd_RS_544_514
_Scrambled_Idle‘
:DATA:SEQuence:SET
'M1.DataOut1',Memory,'factory:FEC/IEEE_802_3cd_RS_544_514
_Remote_Fault'
2 Commands for FEC error insertion:
a Enable/disable symbol error insertion
:DATA:FEC:EINSertion:STATe 'M1.DataOut1',<0|1|OFF|ON>
b Set the number of symbol errors per FEC frame
:DATA:FEC:EINSertion:ERRors 'M1.DataOut1',<NR1>
c Insert a single BIP error
:DATA:FEC:EINSertion:BIP:ONCE 'M1.DataOut1';*OPC?
For further details on these SCPI commands, please refer to the M8000
Series Programming Guide.
