Inter-Module Phase
Synchronization
Command Summary
Phase Synchronization commands control the phase offset between
two or more modules. There is no limit on how many modules can be
synchronized, as long as one module is programmed to be master
and the rest of the modules are slaves. The location of the slave
modules in relation to the master module does not affect the
accuracy of the phase offset.
The commands are presented exactly as they should be typed in
your program. Optional nodes were omitted from these commands.
Factory defaults after *RST or front panel reset are shown in bold
typeface. Parameter low and high limits are given where applicable.
