FIGURE B-5. USING LIST COMMANDS AND QUERIES (SHEET 1 OF 2)
B.48 [SOURce:]LIST:COUNt COMMAND
LIST:COUN
Syntax:
Short Form: LIST:COUN
Description: Establishes how many times the list is executed. Allows user to establish how many times the list
is executed. For LIST:COUN 0, the unit will execute the sequence indefinitely until a VOLT:MODE
FIXED, command is received. (See example, Figure B-5.)
B.49 [SOURce:]LIST:COUNt? QUERY
LIST:COUN?
Syntax:
Short Form: LIST:COUNT?
Long Form: LIST:COUNt?
Return Value:
Description: Identifies how many times the list will be executed. Returns value set by LIST:COUN command.
(See example, Figure B-5.)
NOTES:
Examples below are intended only to illustrate command functions. Refer to PAR. 3.5.2 for pro-
gramming techniques to optimize performance.
LIST:CLEAR
Initializes the list process.
LIST:RES?
Returns 0.000093,0.034000,nnnn (where nnnn = total number of points
available).
LIST:VOLT:POINTS? Returns
0.
LIST:VOLT:POINTS? MAX
Returns 5900.
LIST:VOLT:APPLY SINE,15,10 Causes the BOP to generate points.for 15Hz sine wave, 10V p-p.
LIST:VOLT:POIN?
Returns 480 - indicating the unit used 480 points for the sine wave.
LIST:VOLT:POIN? MAX
Returns 3933 - indicating up to 3933 points can be used.
LIST:DWEL:POIN?
Returns 480 - indicating 480 points have been assigned dwell times.
LIST:DWEL?
Returns 1.38e-4 indicating the unit used
138 microseconds per division (automatically selected as the best possible
dwell for the waveform).
FUNC:MODE VOLT
Initializes the power supply mode to be voltage.
LIST:CLEAR
Initializes the list processor to add entries, clears main channel (LIST:CURR
or LIST:VOLT) and LIST:DWEL data tables (Table B-2).
LIST:VOLT -20,-18,-16,-14,-12,-10,-8,-6,-4,-2,0
Starting at location 0 (-20), up to location 10 (0), fills the list with 11 data
points.
LIST:VOLT:POIN?
Returns 11. Indicates that 11 data points have been entered, and location
11 is the next location to be filled (for the 12th data point.
NOTE: See PAR. B.2 for format and accuracy of all numerical data returned.
LIST:QUERY?
Returns 0 (pointer cleared by LIST:CLE).
LIST:VOLT?
Returns -20,-18,-16,-14,-12,-10,-8,-6,-4,-2,0 (the contents of locations 0
through 10). (See PAR. B.2 for format and accuracy of numerical data.)
list:volt 2,4,6,8,10,12,14,16,18,20
Adds 10 points to the list (location 11 through 20). List now has 21 points.
LIST:VOLT:POIN?
Returns 21 (the next location to be filled by LIST:VOLT).
LIST:COUNT 100
Specifies that when VOLT:MODE LIST is issued, the user-determined
sequence will be executed 100 times. (21 steps in the list will be executed
100 times)
CURR 1;VOLT -20
initializes the BOP output
OUTPUT ON
Turns the output on (BOP now provides -20 volts)
LIST:DWELL .010
Sets the time duration for location 0 to be 0.010 second (Since dwell times
for the rest of the locations in the list are not entered before running the list,
the dwell time will be 0.010 second for all locations.
