The letter “C” in the “SCPI” column means that the command syntax is SCPI compliant; an
“N” in the “SCPI” column means that the command syntax is not part of the SCPI definition.
Following this command reference table, are some annotated examples showing how to
create a sequence (program) in your power supply.
Command
Description
SCPI
PROGram
Program subsystem
C
:INITializing?
This query returns 1 after mains power-on, and
continues to return 1 until the program/sequence
functionality is fully initialized, after which point 0 is
returned. Do not attempt to use any of the other
sequence related commands--i.e., commands in the
SCPI PROG command tree --while program/sequence
functionality is initializing. (Typical initialization time is
approx. 15 seconds after power-on.)
N
:CATalog?
Lists all the defined sequence names. The format for
the response to the query is a list of comma-separated
test names.
C
:[SELected]
Selected section of program subsystem
C
:ARM
Prepares the presently selected sequence for
execution; this command may take a few seconds
depending the length of the selected sequence and all
subsequences that the selected sequence may depend
upon. The command to use to execute an armed
sequence is
PROG:STAT RUN
.
N
:ARM?
A return of 1 means the sequence is armed.
A return of 0 means it is not.
N
:DEFine <step#>,
VIMODE, <volts>, <amps>,
<ovp>, <s>
Programs the
VIMODE
sequence command into the
selected sequence (see
PROG:SEL:NAME
command) at
<step#>. The following values set by this command:
voltage <volts>, current <amps>, over voltage
protection <ovp>, and duration of <s> seconds. <s>
may have a decimal value with a granularity of 0.001
seconds. This command is valid for steps 1 thru 20.
C
:DEFine <step#>,
RAMPTOV,<start
volts>,<end volts>,
<amps>, <ovp>,<s>
Programs the
RAMPTOV
sequence command into the
selected sequence at <step#>. The following values
are programmed: starting and ending voltage ramp
values <start volts> and <end volts>, current <amps>,
over voltage protection value <ovp>,and voltage
ramping duration in <s> seconds. <s> may have a
decimal value with a granularity of 0.001 seconds. This
command is valid for steps 1 thru 20.
