9.3 Initial and final states
As in simple table mode, when the
ready the table for execution, the output is enabled and amplifiers
switched on (if present). The state of the
the same as the last table instruction that was run.
In simple table mode, the first instruction specified all three pa-
rameters, so the state at each step is well-defined and repeatable.
However, in parallel mode only one parameter is specified and the
other two may be undefined. It is strongly recommended that the
start and end of every table reset all parameters to known values,
as demonstrated in the listing below.
TABLE,CLEAR,1
TABLE,XPARAM,1,POW
# create table entry specifying a known start condition
TABLE,APPEND,1,80MHz,5dbm,45deg,976ns,OFF
# activate the update
TABLE,APPEND,1,POW,5dbm,16ns,UPD
# 1us has elapsed up to here

# ... other table mode entries ...

# add a final entry to reset rf state
TABLE,APPEND,80MHz,5dbm,45deg,1us
# activate the update, and turn off the rf

Listing 9.4: Setting initial and final states in parallel mode
The state at the last instruction is held after the table has finished
RF
executing, which may involve the
the desired application. If it is desired for the
off, then the amplitude should be set to zero on the final instruction
instead of using the
immediately following the next table rearm.
It is also possible to manually use the commands
in advanced table mode to set the initial conditions when the
PHASE
table is not running. Once the table has finished executing, the last
