*RST
Reset the function generator to its factory default state (see “Factory
Default Settings” on page 127) independent of the MEM:STAT:REC:AUTO
command setting. This command will abort a sweep or burst in progress
and will re-enable the front-panel display if it was previously disabled
(DISP OFF command).
*TST?
Perform a complete self-test of the function generator. Returns “+0”
(PASS) or “+1” (FAIL). If the test fails, one or more error messages
will be generated to provide additional information on the failure.
Use the SYST:ERR? command to read the error queue (see page 213).
SYSTem:VERSion?
Query the function generator to determine the present SCPI version.
Returns a string in the form “YYYY.V”, where “YYYY” represents the
year of the version, and “V” represents a version number for that year
(e.g., 1997.0).
SYSTem:BEEPer
Issue a single beep immediately.
SYSTem:BEEPer:STATe {OFF|ON}
SYSTem:BEEPer:STATe?
Disable or enable the tone heard when an error is generated from the
front-panel or over the remote interface. The current selection is stored
in non-volatile memory. The :STAT? query returns “0” (OFF) or “1” (ON).
*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.
