B-14 BOP-1K 031912B.50 [SOURce:]LIST:COUNt COMMAND LIST:COUNSyntax: Short Form: LIST:COUN Long Form: LIST:COUNt> Description: Establishes how many times the list is executed. Allows user to establish how many times the listis executed. For LIST:COUN 0, the unit will execute the sequence indefinitely until a VOLT:MODEFIXED, 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: Description: Identifies how many times the list will be executed. Returns value set by LIST:COUN command.(See example, Figure B-5.)FIGURE B-5. USING LIST COMMANDS AND QUERIES (SHEET 2 OF 2).VOLT:MODE LIST Executes the list. For 240 mS the BOP outputs a staircase triangle wavefrom -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? Returns +20 (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 thatincreases from -20V to +20V and repeats 10 times. There is an abruptchange from +20V to -20V each time the list transitions from location 20 tolocation 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,.01Enters 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 indicatingthe lists are not balanced.LIST:DWELL:POINTS? Returns 11 to indicate the dwell list has 11 entriesLIST:VOLT:POINTS? Returns 21 to indicate the voltage list has 21 entries.LIST:DWELL .01,.01,.01,.01,.01,.01,.01,.01,.01,.01Dwell 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 0LIST:QUER 9 Causes list queries to start at location 9LIST:DWEL? Returns 01,.03,.01,.01,.01,.01,.01,.01,.01,.01,.01,.01(the dwell times forlocations 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 listLIST:VOLT:APPLY SINE,60,20 Adds a 60Hz, 20V p-p sine wave to the current waveformVOLT:MODE:LIST Unit outputs the staircase and then the sine wave.*RST Unit stops generating the waveform.
