FIGURE B-6. USING LIST COMMANDS AND QUERIES (SHEET 2 OF 2)
B.60
[SOURce:]LIST:COUNt? QUERY
LIST:COUN?
Syntax:
Short Form: LIST:COUNT?
Long Form: LIST:COUNt?
Return Value: <int_value>
Description:
Identifies how many times the list will be executed.
Returns value set by LIST:COUN command.
(See example, Figure B-6.)
B.61
[SOURce:]LIST:COUNt:SKIP COMMAND
LIST:COUN:SKIP
Syntax:
Short Form: LIST:COUN:SKIP nn
Long Form: LIST:COUNt:SKIP nn
nn = <int_value 0 to 255>
Description:
Allows beginning steps of list-generated waveform to be run once, then ignored.
When a list is to be repeated using LIST:COUNT, this command allows the user to skip the first nn
steps once the full set has been executed. After the first iteration (which executes all steps), the first
nn steps are skipped. The LIST:COUN:SKIP command allows the user to precondition a list-generated
waveform by setting unique conditions at the beginning that are not repeated for the rest of the repeti-
tions. LIST:CLEar sets nn to 0. Related Commands: LIST:COUN, LIST:COUN:SKIP?, LIST:CLE. (See
example, Figure B-6.)
VOLT:MODE LIST
Executes the list. For 240 mS the BOP outputs a staircase triangle wave
from -20V to +20V and back down to -20V. This staircase will have a uni-
form spacing between voltage changes of 10 mS and will repeat 100 times.
VOLT?
R20 (the last step in the list set the unit to +20V.
LIST:COUNT?
Returns 100.
LIST:COUNT 10
Determines that the list will be repeated 10 times when executed.
LIST:COUNT?
Returns 10.
VOLT:MODE LIST
Initiates execution of the list. The unit outputs a sawtooth waveform that
increases from -20V to +20V and repeats 10 times. There is an abrupt
change from +20V to -20V each time the list transitions from location 20 to
location 0.
VOLT?
Returns 20, (the last step in the list set the unit to 20V.
LIST:DWELL .01,.01,.01,.01,.01,.01,.01,.01,.01
Enters dwell time of 0.01 Seconds in locations 1 through 9.
LIST:DWELL .03
Enters dwell time of 0.03 Second in location 10.
VOLT:MODE LIST
the list is not executed, the unit returns error -221,Settings Error indicating
the lists are not balanced.
LIST:DWELL:POINTS?
Returns 11 to indicate the dwell list has 11 entries
LIST:VOLT:POINTS?
Returns 21 to indicate the voltage list has 21 entries.
LIST:DWELL .01,.01,.01,.01,.01,.01,.01,.01,.01,.01
Dwell times are entered in locations 11 through 20.
DWELL:POINTS?
Returns 21 indicating there are now 21 step dwell times on the list.
LIST:QUER?
Returns 0 indicating list queries will start from location 0
LIST:QUER 9
Causes list queries to start at location 9
LIST:DWEL?
Returns 01,.03,.01,.01,.01,.01,.01,.01,.01,.01,.01,.01(the dwell times for
locations 9 through 20.
LIST COUNT 0
List will repeat indefinitely.
VOLT:MODE LIST
The list is executed. Stair case wave now consists of 21 steps of 0.01 Sec-
onds except for the 0V step (location 10) which outputs 0V for 0.03 Second.
LIST:DWEL?
Returns error -221,Settings Error because a LIST command cannot be exe-
cuted while the LIST is still being executed.
VOLT:MODE FIX
Stops execution of the list
LIST:VOLT:APPLY SINE,60,20 Adds a 60Hz, 20V p-p sine wave to the current waveform
VOLT:MODE:LIST
Unit outputs the staircase and then the sine wave.
*RST
Unit stops generating the waveform.
