B.52 [SOURce:]LIST:CURRent COMMAND
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.).

B.53 [SOURce:]LIST:CURRent? QUERY
Syntax:
Short Form: LIST:CURR?
Return Value: <value1>, <value2>, . . . to <value16>
Description: Identifies the parameters (main channel) entered for the list. Starting at location established by
LIST:QUERy, returns comma-separated list of up to 16 values indicating the main channel parameters
entered. i.e., the contents of main channel locations of Table B-2. Related Commands: LIST: CURR,
LIST:QUERy. If LIST:VOLT has any entries, an error message: -221,"Settings conflict" is posted in the
error queue. (See example, Figure B-5.)
B.54 [SOURce:]LIST:CURR:APPLy COMMAND
Syntax:
Short Form: LIST:CURR:APPL <type>,<value1>,<value2>[,<value3>]
Long Form: LIST:CURRent:APPLy <type>,<value1>,<value2>[,<value3>]
Where <type> is {SQUARE | RAMP+ | RAMP- | TRIANGLE | SINE | LEVEL}
<value1> is frequency (or period (duration) for LEVEL
<value2> is p-p amplitude (or amplitude (offset) for LEVEL
<value3> is offset (optional, default is 0, not applicable to LEVEL)
Description: Causes the unit to add a series of points to both the list:curr array and the list:dwell array to
make either a level or a waveform of one of five types. Refer to table 3-11 for a description of the
waveform types. The waveform type specified is generated at the frequency specified with a peak-to-
peak amplitude centered on zero. If the optional offset value is specified, the center of the generated
series of points is moved off zero. The apply generator takes into account the soft limits for the current
channel and insures the generated array does not exceed the unit's capabilities.
B.55 [SOURce:]LIST:CURRent:APPLy:SWEep COMMAND
Syntax:
Short Form: LIST:CURR:APPL:SWE <value1>,<value2>
Long Form: LIST:CURRent:APPLy:SWEep <value1>,<value2>
Where <value1> is start angle. Valid from 0 to 359.99 degrees.
<value2> is stop angle. Valid from 0.01 to 360.00 degrees
Description: Allows the user to provide a starting angle for either triangle and sine waveforms and an
optional stop angle. If the stop angle is not supplied, the unit defaults to 360 degrees. This command
should be placed at the beginning of the waveform program to be applicable to all sine and triangle
waveform segments.
