Section IV – Operating Instructions
1830A Error/Status Reporting
A status is returned from the 1830A after each command. Each status, or error code, is
comprised of two digits followed by a colon. (i.e. 12:). The error code indicates if there was
problem with the command. See Table 4.5 for error codes.
System Commands
System commands (summarized in Table 4.1) are device commands that control the basic
functionality of the 1830A. They are similar in fashion to IEE-488.2 Common Commands such as
*RST.
Command Description
*IDN? Responds with identification of the instrument in SCPI format.
CLOSE or QUIT
Close the current connection to the 1830A. Used only for TCP
connections, using these commands with other connection types will
have no effect.
SHUTDOWN
Causes the unit to power down. Equivalent to pushing the power
button on the front panel when the instrument is on.
RESTART Causes the unit to reset.
LOCK Locks out all inputs (front panel, USB and LAN) except the one the
LOCK was sent on (USB and LAN). This allows only 1 user to control
the system at a time, with no other access allowed. For example, if
the LOCK command is sent across the USB, the 1830A will ignore
commands from the LAN port as well as the front panel.
UNLOCK Unlocks the 1830A from dedicated access. Must be issued from the
same port that the LOCK command was issued from.
