Ppd Mapping; Ppe Mapping - Agilent Technologies EPM-P Series Programming Manual

IEEE488.2 Command Reference
Universal Commands
PPC
When addressed to listen, the PPC (Parallel Poll Configure) command will
cause the power meter to be configured according to the parallel poll
enable secondary command which should follow this command.
PPD
Sending the PPC command followed by the PPD (Parallel Poll Disable)
command will disable the power meter from responding to a parallel poll.
This is effectively a selective disable.
