FIGURE B-3. USING LIST COMMANDS AND QUERIES (SHEET 1 OF 2)

NOTE:

Examples below are intended only to illustrate command functions. Refer to PAR. 3.3.6 for pro-
gramming techniques to optimize performance.

LIST:CLEAR

Initializes the list processor to add entries, clears main channel (LIST:CURR
or LIST:VOLT) and LIST:DWEL data tables.

LIST:DWELL .010

Sets the time duration for location 0 to be 0.010 second (Since dwell times
for the rest of the locations in the list are not entered before running the list,
the dwell time will be 0.010 second for all locations.

LIST:VOLT 0,2,4,6,8,10,12,14,16,18,20

Starting at location 0 (0), up to location 10 (20), fills the list with 11 data
points.

LIST:VOLT:POIN?

Returns 11. Indicates that 11 data points have been entered, and location
11 is the next location to be filled (for the 12th data point.

NOTE: See PAR. B.2 for format and accuracy of all numerical data returned.

LIST:QUERY?

Returns 0 (pointer cleared by LIST:CLE).

LIST:VOLT?

Returns -20,-18,-16,-14,-12,-10,-8,-6,-4,-2,0 (the contents of locations 0
through 10). (See PAR. B.2 for format and accuracy of numerical data.)

LIST:VOLT 18,16,14,12,10,8,6,4,2,0

Adds 10 points to the list (location 11 through 20). List now has 21 points.

LIST:VOLT:POIN?

Returns 21 (the next location to be filled by LIST:VOLT).

LIST:VOLT?

Returns 0,2,4,6,8,10,12,14,16,18,20,18,16,14,12,10,8,6,4,2,0 (the contents
of locations 0 through 20).

LIST:QUERY 16

Start LIST queries from location 15.

LIST:QUERY 32

Start LIST queries from location 31.

LIST:COUNT 100

Specifies that when VOLT:MODE LIST is issued, the user-determined
sequence will be executed 100 times. (44 steps in the list will be executed
100 times)

LIST:COUN:SKIP 4

Specifies that the first 4 steps of the sequence will only be executed the first
time through the list. For the subsequent 99 iterations established by
LIST:COUNT 100, location 0 (0V) will last 10 milliseconds.

CURR .001;VOLT 20

initializes the BHK output

OUTPUT ON

Turns the output on (BHK now provides 0 volts)

LIST:CURR .001

Established current level for list.

VOLT:MODE LIST

Executes the list. For 40 milliseconds the BHK outputs 0V, then outputs a
staircase triangle wave from 0V to +20V and back down to 0V. This stair-
case will have a uniform spacing between voltage changes of 10 millisec-
onds and will repeat 100 times.

VOLT?

Returns 0 (the last step in the list set the unit to 0V.

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 0V to +20V and repeats 10 times.

VOLT?

Returns 0, (the last step in the list set the unit to 0V.

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 0V then increases to 20V in 2V steps and repeats 10 times. The saw-
tooth is similar to the previous sawtooth, except the waveform is inverted.
