5 SCPI Command Reference
:DATA:LINecoding[:VALue][?]
Syntax :DATA:LINecoding[:VALue] ‘identifier’, NRZ | PAM4
:DATA:LINecoding[:VALue]? ‘identifier’
Input
Parameters
<identifier>: Any valid data output or data input identifier. M*.DataOut1,
M*.DataOut2, M*.DataOut3, M*.DataOut4 and M*DataIn
Description The command selects the line coding to be used. The availability of
individual selections depends on the hardware capabilities.
This query returns the present state.
This SCPI is applicable for M8195A, M8196A, M8045A and M8046A.
Example :DATA:LIN ‘M1.DataOut1’, PAM4
:DATA:LIN ‘M2.DataIn’, PAM4
:DATA:LINecoding:PAM4:MAPPing[?]
Syntax :DATA:LINecoding:PAM4:MAPPing ‘identifier’, NONE | GRAY | CUSTom
:DATA:LINecoding:PAM4:MAPPing? ‘identifier’
Input
Parameters
<identifier>: Any valid data output or data input identifier. M*.DataOut1,
M*.DataOut2, M*.DataOut3, M*.DataOut4 and M*DataIn
Description The command selects how the pattern bits are mapped to symbol
numbers.
• Select NONE if the mapping shall be ‘transparent’. This is useful if the
pattern does already contain the required coding scheme. This option is
available for M8195A, M8045A and M8046A.
• Select GRAY if consecutive pairs of bits shall be Gray coded in order to
map to the PAM-4 symbols. This option is available for M8195A
M8045A and M8046A.
• Select CUSTom to use a user defined mapping definition. This option is
only available for M8045A and M8046A.
This query returns the present state.
This SCPI is applicable for M8195A, M8196A, M8045A and M8046A.
Example :DATA:LIN:PAM4:MAPP ‘M1.DataOut1’, NONE
:DATA:LIN:PAM4:MAPP ‘M2.DataIn’, CUST
