Miscellaneous Commands and Queries
Miscellaneous commands and queries are summarized in Table 27.
Table 27. Miscellaneous Commands and Queries
Command Description
^C (CNTRL C)
SERIAL?
The RS-232 equivalent of IEEE-488 DCL. Causes <CR><LF> and =><CR><LF> to
be output.
Meter returns its serial number.
RS-232 Remote/Local Configurations
The commands in Table 28 are used with the RS-232 interface to set up the Remote/
Local configuration of the Meter. These commands are valid only when the RS-232
interface is enabled.
Table 28. RS-232 Remote/Local Configuration Commands
Command Description
REMS
RWLS
LOCS
LWLS
Puts the Meter into remote state where all front-panel keys, except the local key, are
disabled. LOCAL is shown above the first soft key in the display.
Puts the Meter in the remote state, with front-panel lockout. LOCKED is shown in the display.
When in RWLS, all front panel buttons are disabled.
Puts the Meter in the local state, i.e., local operating mode without lockout. All front panel
buttons are enabled.
Puts the Meter in the IEEE-488 LWLS state, i.e., local operating mode lockout. All
front panel buttons are disabled.
Triggering Output
The Meter takes measurements when it is triggered to do so. The five available trigger
types are listed in Table 29. All available trigger methods fall into two basic categories:
• Internal triggering uses the Meter’s internal trigger circuit for a continuous source of
triggers.
• External triggering comes from a source outside the Meter controlled by the user.
Setting the Trigger Type Configuration
To select a trigger type over the computer interface, send the command:
TRIGGER <type>
where <type> is a number between 1 and 5 that identifies a trigger type. If <type> is not
one of these numbers, an Execution Error is generated.
Select a trigger type that enables the settling delay (type 3 or 5) when the input signal is
not stable before a measurement is triggered.
