FIGURE B-2. USING LIST COMMANDS AND QUERIES
B.34 OUTPut[:STATe] COMMAND
OUTP
Syntax: Short Form: OUTP[:STAT] {ON | OFF} or {1 | 0} (1 = on, 0 = off)
Long Form: OUTPut[:STATe] {ON | OFF} or {1 | 0} (1 = on, 0 = off)
Description: Enables or disables the power supply output (see KLP User manual for disabling if analog pro-
gramming used). Upon power up the output is enabled (OUTP ON). When OUTP OFF is executed,
the digitally programmed values of voltage and current are saved, then voltage and current are pro-
grammed to 0; analog programming is not affected. When OUTP ON is executed, the power supply
output is restored to the previously saved programmed values. The saved values of voltage and cur-
rent can be viewed by VOLT? and CURR? queries. Related Commands: OUTP?. (See example, Fig-
ure B-1.)
NOTE: The following example assumes KLP 75-33-1200 with virtual model set for 36V, 33.33A and out-
put operating in voltage stabilization mode. See Figure B-3 for directions on programming virtual
model limits.
LIST:CLE Clears main channel (LIST:CURR or LIST:VOLT) and LIST:DWEL
data tables and initializes the LIST processor to add entries.
LIST:DWEL 2 Sets the time duration for Location 0 to be 2 seconds. NOTE: If spe-
cific dwell times are not entered for the rest of the locations in the list
before running the list, this dwell time will be assigned to all entries.
LIST:VOLT 28,32,18 Starting at Location 0, fills the first three locations with the voltages
shown.
LIST:VOLT:POIN? Returns 3, indicating that 3 data points have been entered; also indi-
cates that the next data location to be filled is Location 3.
LIST:QUER? Returns 0 indicating list starting point (default location set by
LIST:CLE).
LIST:VOLT? Returns 2.8E1,3.2E1,1.8E1 (the contents of the filled locations).
LIST:VOLT 20,22,24,26,28 Adds five points to the list (Locations 3 through 7). The list now has
eight points.
LIST:VOLT:POIN? Returns 8.
LIST:QUER 3 Starts LIST queries from Location 3.
LIST:COUN 10 Specifies that upon receipt of VOLT:MODE LIST, the above
sequence will be executed 10 times.
LIST:COUN:SKIP 2 Specifies that the first two steps of the sequence will only be exe-
cuted during the first cycle through the list; thereafter, the list shall
execute Locations 2 through 7 an additional 9 times.
LIST:CURR 3 Programs output current to 3A for all locations. NOTE All active loca-
tions must have complete sets of data entered, or list will not run.
LIST: CONT 0 Programs relay control to de-energized state. NOTE: This command
is necessary only if the relay control is set to LIST (see PAR.
3.2.11.3).
OUTP ON Enables output.
VOLT 24;CURR 3 Initializes output voltage to 24V, output current to 3A.
VOLT:MODE LIST Executes the list. For the first cycle the voltage will step to 28V and
32V in 2-second dwell increments, then begin a cycle of steps from
18V to 28V in 2V steps and 2-second dwell increments repeated ten
times, at the end of which time the output will remain constant at
28V and 3A.
VOLT:MODE FIX Halts execution of the list and maintains the outputs at their immedi-
ate settings.
