:SYSTem:PRESet
Th
e command triggers an instrument reset. It has the same effect as the PRESET key of the manual
control or as command *RST. This command triggers an event and hence has no *RST value.
Note: By means of the "Preset RF State" item in the Level/Level menu, it is possible to
determine the switching state of the RF connector. The selected state is activated
when the :SYST:PRES command is sent.
If "Preset RF State“ = OFF, the command has the same effect as *RST
Example: :SYST:PRES
:SYSTem:PROTect[1|2|3|4]
The command to disable certain instrument functions is under this node. A list of the functions
concerned can be found in the manual control (Chapter 4, Section "Password Input With
Protected Functions"). There are four protection levels which are distinguished by means of a
suffix after PROT. *RST has no effects on the disabling/enabling of the instrument functions.
:SYSTem:PROTect[1|2|3|4][:STATe] ON | OFF, Password
The command switches a protection level on or off. The passwords are 6-digit numbers. They
are fixedly stored in the firmware. The password for the first level is 123456.
ON disables the functions belonging to this protection level. A password doesn't have to
be entered.
OFF deactivates the disabling again if the correct password is entered. Otherwise an error
-224, "Illegal parameter value" is generated and STATe remains ON.
Example: :SYST:PROT1:STAT OFF, 123456
:SYSTem:SECurity[:STATe] ON | OFF
The command switches the security state on or off.
ON The following commands cannot be executed:
:DISP:ANN:ALL ON
:DISP:ANN:FREQ ON
:DISP:ANN:AMPL ON
OFF In the transition from ON to OFF all data existing in the instrument except for the
calibrating data are deleted, especially all status registers, all instrument states and
all lists.
The command is not influenced by *RST and *RCL.
Example: :SYST:SEC:STAT ON
:SYSTem:SERRor?
This command returns a list of all errors existing at the point of time of the query. The error
messages are separated by commas. This list corresponds to the indication on the ERROR page
with manual control (cf. Chapter 9, Section "Error Messages").
Example: :SYST:SERR?
Answer: -221, "Settings conflict", 153, "Input voltage out of range"
:SYSTem:VERSion?
The command returns the SCPI version number the instrument acts in accordance with. This
command is a query and thus has no *RST value.
Example: :SYST:VERS? Answer: 1994.0
