B.50 [SOURce:]LIST:COUNt COMMAND
LIST:COUN
Syntax: Short Form: LIST:COUN<int_value 0 to 255> Long Form: LIST:COUNt> <int_value 0 to 255>
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.51 [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-5.)

.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.
