As soon as FlexDCA is integrated into M8070A, it will no longer be
accessible for interactive use.
All remote programming of FlexDCA must be done through M8070A. For
more details on the SCPI commands, refer to M8000 Series Programming
Guide. Since M8070A is only supporting a subset of the FlexDCA
functionality, this will restrict the use of FlexDCA to the control of
N1076A/77A. Any other functionality is not accessible through M8070A.
These are basically the same SCPI commands that are defined by
FlexDCA.
The difference to FlexDCA is that they are located under the root node
:N1000, there is no suffix for :SLOT and :CREC, and that there is an extra
command argument which holds the M8070A specific identifier (e.g.
DCA1.Slot2). But functionality is exactly like when controlling a N1010A
FlexDCA directly.
The only M8070A specific command is
:N1000:EMODules:SLOT:CONNect[?]<identifier>,{ON | OFF
| 1 | 0}
This command controls if the specific slot is being enabled to be used by
M8070A. It does not establish the connection between N1010A and
N1076A/77A. Connecting the N1076A/77A must be done within N1010A
prior starting M8070A.
The FlexDCA SCPI Commands are documented in the N1010A FlexDCA
online help.
The M8070A documentation shall only have a basic description for the
FlexDCA specific commands and point the user to the detailed
documentation at the FlexDCA side.
When the line coding “PAM4” is selected for the loopback mode, it is
recommended to adjust the pattern generator data output de-emphasis
for the post cursor for error free operation (e.g. +0.05 at 25 Gbaud).
