command or query is provided. Examples are also provided where
appropriate. Return strings may be up to 80 characters in length.
4.5.1 System-Related Commands
‡
*IDN?
Return the instrument’s identification string. The identification string
contains the AMI model number and firmware revision code.
‡
*RST
Resets the instrument. This is equivalent to cycling the power to the
instrument using the power switch. All non-volatile calibration data and
battery-backed memory is restored. Status is cleared according to the
*PSC setting.
‡
*TST?
Performs a self-test. Currently always returns “1”.
‡ < Ctrl-C >
Equivalent to sending a Device Clear message over the IEEE-488
interface. <
Ctrl-C > is only accepted from the serial interface. This clears
the output buffers of the instrument and prepares the instrument for a
new command. Status registers are unaffected. <
Ctrl-C > corresponds to
ASCII code 03.
‡
SYSTem:LOCal
Enables all front panel controls. All front panels controls are enabled by
default after a power-up or
*RST command.
‡
SYSTem:REMote
Note
The SYSTem:REMote command only disables the front panel
controls for purposes of preventing accidental operation of a front
panel feature. It is not necessary for this command to be sent prior
to using a remote interface. Send the SYSTem:LOCal command,
cycle instrument power, or send the *RST command to reenable the
front panel controls.
Disables all front panel controls. If the Model 420 is in the remote mode,
an asterisk (
) will appear in the front panel display in the position just
below the ramping character as shown below.
