M*.DataOut1,M*.DataOut2, M*.DataOut3, M*.DataOut4 and M*DataInDescription The command selects the line coding to be used. The availability ofindividual 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’InputParameters: Any valid data output or data input identifier. M*.DataOut1,M*.DataOut2, M*.DataOut3, M*.DataOut4 and M*DataInDescription The command selects how the pattern bits are mapped to symbolnumbers.• Select NONE if the mapping shall be ‘transparent’. This is useful if thepattern does already contain the required coding scheme. This option isavailable for M8195A, M8045A and M8046A.• Select GRAY if consecutive pairs of bits shall be Gray coded in order tomap to the PAM-4 symbols. This option is available for M8195AM8045A and M8046A.• Select CUSTom to use a user defined mapping definition. This option isonly 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
