FIGURE B-6. USING LIST COMMANDS FOR SAWTOOTH AND TRIANGLE WAVEFORMS
SIMPLE STAIRCASE SAWTOOTH WAVEFORM EXAMPLE
*RST Resets power supply to the default state.
CURR 1 Sets programmed current to 1A.
LIST:CLE Clears all list entries by setting all pointers to 0.
LIST:VOLT -5,-4,-3,-2, -1,0,1,2,3,4,5 Create 10 steps that increases from -5V to +5V.
LIST:DWEL 2 Set the dwell time for each step to 2 seconds.
LIST:COUN 10 Determines that the list will be repeated 10 times when executed.
OUTP ON Turns the BOP output on.
VOLT:MODE LIST Initiates execution of the list.
Upon sending VOLT:MODE LIST, the unit outputs a sawtooth waveform that increases from -5V to +5V and
repeats 10 times. Each step is 1V with a dwell time of 2 seconds. There is an abrupt change from +5V to -5V
each time the list transitions from the last step to the first step of the waveform. After the waveform repeats
10 times, the list stops running and the unit output will be +5V (the last step in the list). The total list running
time is equal to:
10 (from LIST COUN) x 11 (total number of list steps) x 2 seconds (dwell time of each step) = 220 seconds
SIMPLE STAIRCASE TRIANGLE WAVEFORM EXAMPLE
*RST Resets power supply to the default state
CURR 1 Sets programmed current to 1A
LIST:CLE Clears all list entries by setting all pointers to 0.
LIST:VOLT 0,1,2,3,4,5,6,7,8,9,10 Create 11 steps that increase from 0V to +10V.
LIST:VOLT 9,8,7,6,5,4,3,2,1,0 Create 10 steps that decrease from +9V to 0V. The 21-step list
forms a triangle stair waveform that first increases from 0V to +10V
and then decreases to 0V.
LIST:DWEL 2 Sets the dwell time for each step to 2 seconds.
LIST:COUN 10 Determines that the list will be repeated 10 times when executed.
OUTP ON Turns the BOP output on
VOLT:MODE LIST Initiates execution of the list.
The unit outputs a triangle stair waveform, that increases from 0V to +10V and then decrease to 0V. The
waveform repeats 10 times. Each step is 1V with a dwell time of 2 seconds. The waveform stays at 0V for 4
seconds because for each repetition, the last step of the decreasing list and the first step of the increasing
list are both 2 seconds at 0V. When the list stops running, the output will be 0V (the last step of the list). The
total list running time is equal to:
10 (from LIST COUN) x 21 (total number of list steps) x 2 seconds (dwell time of each step) = 420 seconds
To eliminate the first step and make the waveform times even, when the list stops running, add the following
command between OUTP ON and VOLT:MODE LIST above.
LIST:COUN:SKIP 1 Skip first step (0V level) after the first iteration
Upon sending VOLT:MODE LIST, the unit outputs a triangle stair waveform, that is identical to the original,
except that the first step (0V) is only executed for the first iteration. After 10 repetitions the list stops running
and the output is 0V. The total list running time is equal to:
10 (from LIST COUN) x 20 (total number of repeated list steps) x 2 seconds (dwell time of each step) = 400
s 2 seconds (dwell time of first step, run only once) = 402 seconds.
