B-11
FIGURE B-3. USING LIST COMMANDS AND QUERIES (SHEET 2 OF 2)
LIST:GEN DSEQ Changes the list to execute sequentially from locations 0 through 20).
LIST:COUN:SKIP? Returns 4. Skip first 4 steps after the first time through count.
LIST:COUN:SKIP 0 Specifies no steps to be skipped after the first time through the count.
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:VOLT:POIN? Returns 21 (the next location to be filled by LIST:VOLT).
LIST:VOLT 10,0,-10 Add 3 points to the list (location 21 through 23).
LIST:COUN? Returns 10 indicating that the list will be repeated 10 times when executed.
LIST:DIR? Returns UP (the default.)
LIST:DIR DOWN Reverses the sequence order.
VOLT:MODE LIST The list (24 steps) is executed. The output starts at -10V, goes to 0V, to 10V
to 20V then decreases to -20V in 2V steps and repeats 10 times. The saw-
tooth is similar to the previous sawtooth, except the waveform is inverted
and the abrupt change from -20 to +20 is executed in three steps of 10
volts.
LIST:GEN? Returns DSEQ (default sequence))
LIST:GENERATION:SEQ Changes sequence to user determined sequence.
VOLT:MODE:LIST The original list of 4400 points will be executed (without the three new
steps.)
LIST:QUERy 0 Sets query pointer to zero.
LIST:DWEL:POIN? Returns 1 indicating the next dwell time will be entered in location 1.
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 1 Enters dwell time of 1 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 24 to indicate the voltage list has 24 entries.
LIST:DWELL .01,.01,.01,.01,.01,.01,.01,.01,.01,.01,.1,.1,.1
Dwell times are entered in locations 11 through 23.
DWELL:POINTS? Returns 24 indicating there are now 24 step dwell times on the list.
LIST:QUER? Returns 0 indicating list queries will start from location 0
LIST:QUER 18 Causes list queries to start at location 18
LIST:DWEL? Returns .01,.01,.01,.1,.1,.1 (the dwell times for locations 18 through 23.
LIST:VOLT? Returns 16,18,20,10,0,-10
LIST COUNT 0 List will repeat indefinitely.
VOLT:MODE LIST The list is executed. Staircase wave now consists of 24 steps of .01 sec-
onds except for the 0V step (location 10) which outputs 0V for 1 second.
The end of the staircase has three steps of 0.1 second.
LIST:GEN? Returns error -221,Settings Error because a LIST command cannot be
executed while the LIST is still being executed.
VOLT:MODE FIX Stops execution of the list
VOLT? VOLT?Returns -20 (the last step in the list set the unit to -20V.
VOLT: -4 Programs output to -4V
VOLT:MODE TRAN .05 Prepares for a voltage transient lasting 0.05 seconds.
VOLT:RANG 4 Sets unit to 1/4 scale (e.g., for BOB 20-20M, maximum voltage now 5V.
VOLT: 3 Output goes to +3V for 0.05 second, then returns to -4V.
