SCPI commands is that they are common to a wide variety of instruments
and are self documenting in the program listing. Most of the SCPI
commands or queries have a corresponding short form command for ease
of programming. Where possible, the short form commands are the same
as those used other ICS Interfaces. Because most of the configuration
settings may be individually set or queried, the unit does not provide a
combined configuration message output.
At power turn on, the unit restores the last configuration and output values
saved by the *SAV 0 command as the current configuration. The Digital
I/O lines are tristated and pulled passively high until the configuration is
restored at the end of the selftest time. The recalled settings are used as the
current configuration until a command is sent with a new value which then
becomes part of the current configuration. When power is turned off, the
current configuration values are lost. The *SAV 0 command is used to save
the current configuration in the flash memory. Note:-The user should set
all outputs to their correct power-on values before doing a *SAV 0
command. A lock function hides the configuration setting commands and
prevents changes to the configuration parameters when the lock function is
enabled. The unit's address and Status Register settings are not affected by
the lock function.
Note that the address change takes place immediately so any subsequent
commands must use the new address and/or address mode. The new address
and mode must be saved in the unit's Flash memory to be a permanent
change.
