FIGURE B-5. USING LIST COMMANDS AND QUERIES (SHEET 2 OF 2)
B.53 [SOURce:]LIST:COUNt:SKIP? QUERY LIST:COUN:SKIP?
Syntax: Short Form: LIST:COUN:SKIP? Long Form: LIST:COUNt:SKIP?
Return Value: <int_value>
Description: Identifies how many steps will skipped the first time the list is executed. Returns value set by
LIST:COUN:SKIP command. (See example, Figure B-5.)
B.54 [SOURce:]LIST:CURRent COMMAND LIST:CURR
Syntax: Short Form: LIST:CURR <exp_value>, <exp_value>, . . . (to max of 5900 data points for global dwell
time)
Long Form: LIST:CURRent <exp_value>, <exp_value>, . . . (to max of 5900 data points for global
dwell time)
<exp_value> = digits with decimal point and Exponent, e.g., 2.71E1 for 27.1
Description: Adds the current value (in Amps) to list. This command sequentially adds LIST:CURRent values to
the main channel List Data Table locations illustrated in Table B-2. Starting location is indicated by
LIST:CURR:POIN? The maximum number of entries is 2950,3933 or 5900. Since the input buffer of
the BOP has a limit of 253 characters, multiple commands are necessary to complete the full 3933
entries of the list. If LIST:VOLT has any entries, an error message: -221,”Settings conflict” is posted in
the error queue. Related Commands: LIST:CURR:POIN?. (See example, Figure B-5.).
.VOLT:MODE LIST Executes the list. For 240 milliseconds the BOP outputs a staircase triangle
wave from -20V to +20V and back down to -20V. This staircase will have a
uniform spacing between voltage changes of 10 milliseconds 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 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 .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.
