System Functions
Save
The register names are stored within the state files, but they are not part of the instrument state; that is,
once you have edited a register name, loading a new state will not change that register name. Another
consequence of this is that the names will be persistent through a power cycle. Also, if a named state file
is transferred to another analyzer, it will bring its custom name along with it.
If you try to edit the name of an empty register, the analyzer will first save the state to have a file to put
the name in. If you load a named state file into an analyzer with older firmware it will ignore the
metadata.
The *SAV and *RCL commands will not be affected by the custom register names, nor will the MMEM
commands.
Register 1 thru Register 16
Selecting any one of these register menu keys causes the State of the currently active mode to be saved to
the specified Register. The registers are provided for rapid saving and recalling, since you do not need to
specify a filename or navigate to a file. Each of the register menu keys annotates whether it is empty or at
what date and time it was last modified. In addition, you can use the Edit Register Names key to enter
custom names for each register.
Although these 16 registers are the only registers available from the front panel, there are 128 state
registers available in the instrument. Registers 17–128 are only available from the SCPI interface, using
the *SAV command.
There is one set of 128 state registers in the instrument, not one set for each Mode. When a state is
saved, the Mode it was saved from is saved with it; then when it is recalled, the instrument switches to
that Mode.
After the save completes, the corresponding register menu key annotation is updated with the date and
time and the message "Register <register number> saved" is displayed.
Trace (+State)
The Save Trace (+State) menu lets you choose a register or file specifying where to save the
