Programming Guide – 48
The following program messages are not valid:
:INP:OFFS 20; INP:WAV 1200 NM (no colon before second command)
:INP:OFFS 20; DISP 1 (DISP command at different level than OFFS)
:INP:OFFS:DISP 1;WAV 1200 NM (WAV command at different level than DISP)
Default Commands
Default commands do not need to be explicitly included in the command path. If a default
command for a path exists, it is enclosed by square brackets ([ ]) in the command tree. If a
default command is implied in the first command of a program message, the command path for
subsequent commands is determined as if the default command had been explicitly included in
the first command header.
:OUTPut
[:STATe] <boolean>
[:STATe?]
APOWeron <boolean>
APOWeron?
:APMode <boolean>
The following program messages are valid:
:OUTP 1;APM 1
:OUTP:STATE:APOW 1; APOW?
:OUTP?;
:OUTP:STAT?
:OUTP:APOW?
:OUTP:STAT:APOW?
The following program messages are not valid:
:OUTP 1; APOW 1 (the APOW command is not at the same level as STAT)
:OUT?: (OUT does not exist; use OUTP)
Parameter Types
The acceptable parameter types for each command or query are listed in the command table
(see the IEEE 488.2 Common Commands section). The following are definitions of each
parameter type:
• Numeric Value—Any value between 9.9E37 and -9.9E37. The value can be sent as an
integer (154), a decimal (15.2), or an exponential number (4.5E6). The character data
forms MIN (minimum), MAX (maximum), and DEF (default) are also acceptable. Other
character data forms can be accepted for specific commands.
• NRf—Any value between 9.9E37 and -9.9E37. The value can be sent as an integer (154),
a decimal (15.2), or an exponential number (4.5E6). The character data forms MIN, MAX,
and DEF are not accepted.
