Interface Operation
71
Command Set
The various features of the instrument may be controlled by the controller sending
certain command “strings” to the instrument.
The features include:
•
Distribution of “space” and non-printing characters between commands
throughout the command string.
•
The ability to use either lower or upper case characters.
•
Capability of sending more than one command before sending the termination
character.
•
Three ways of terminating commands: by the reception of a
line feed
; by the
reception of a character with the EOI line asserted; or by the reception of the
“Group Execute Trigger” command.
Interface Commands
The following commands are available with both the RS232 and the IEEE488
interfaces. They allow
you
to:
•
Control another instrument or power supply via this analog level.
•
Override an analog output used to drive a plotter or alarm output.
CLRDISPLAY—
This command clears all display lines.
CLRUPTIME—
This command clears the timer which may be used to identify the exact time at
which each input’s parametric data was last established (see the ‘
READ=
‘
command’s ‘
UPTIME[i]
’ parameter).
DISP[n]=parameter—
This command specifies that the selected display line (
n
), a possible 0 through 49,
will display the specified parameter. If the optional (
n
) portion is not specified, or
specifies a line beyond the last defined line, then the first undefined line is affected.
The
=
character is optional. See the list at the end of this section for the available
parameter descriptors.
FFT=maxharm/bandwidth/type—
This command configures the FFT based harmonic analysis as defined by
MAXHARM/BANDWIDTH/TYPE
. Refer also to the commands
FUND
and
HARMS
.
