New Focus 3501 - 8 Command Summary; Command Index

24
Commands that may be queried are followed by a ‘?’.
A ‘*’ indicates that the command contains an index (e.g., FR1,FR2,...).
A bracket [ ] indicates that the command accepts a data value. Data ranges
are given in parenthesis. Do not use a decimal point or comma in data. For
example, 5.00 is sent as 500.
Some commands can be used both to set and query an operating parameter.
For instance, the PHS command can be used to set the chopping phase
(PHS900) or to read the value of the phase (PHS?).
The next two pages contain an index and brief description of all fifteen com-
mands. Then, the pages that follow give detailed information about each
