SYSTem:SECurity:IMMediate
Clears all instrument memory except for the boot parameters and
calibration constants. Initializes all instrument settings to their *RST
values. Destroys all user-defined state information, user-defined
arbitrary waveforms, and user-defined I/O settings such as the IP
address. This command is typically used to clear all memory before
removing the instrument from a secure area. This command is not
recommended for use in routine applications because of the
possibility of unintended loss of data.
*LRN?
Query the function generator and return a string of SCPI commands
containing the current settings (learn string). You can then send the
string back to the instrument to restore this state at a later time.
For proper operation, do not modify the returned string before sending
it to the function generator. The returned string will contain about
1,500 characters. To avoid possible instrument errors, execute the *RST
command first, before sending the learn string to the instrument.
*OPC
Set the “Operation Complete” bit (bit 0) in the Standard Event register
after all of the previous commands have been completed. Other
commands may be executed before the bit is set. This command is used
in the triggered sweep or triggered burst modes to provide a way to poll
or interrupt the computer when the *TRG command is complete.
*OPC?
Return “1” to the output buffer after the previous commands have been
completed. Other commands cannot be executed until this command
completes.
*WAI
Wait for all pending operations to complete before executing any additional
commands over the interface.
