Each channel has its own independent table, and there are slots for
four distinct tables in non-volatile memory. Commonly-used tables
can then be stored on the device for later use. However, it should
be noted that stored tables may become inoperable after a firmware
upgrade and tables should be archived in human-readable form.
When a table is armed, the

state remains ongoing. If it is required that the output be disabled
when the table is complete, the final entry should set the power to
0x0 (zero amplitude, not 0 dBm).
Table entries can be defined or queried using the
mand. Once the entries have been set, the
mand should be used to set the length of the table. Alternately, the
TABLE,APPEND
command can be used to add an entry to the end of
the table and update the count automatically.
It is recommended to always explicitly empty the table with the
TABLE,CLEAR
command before defining the entries.
