BIT 4886 051010
B-13
B.45 [SOURce:]LIST:VOLTage COMMAND
LIST:VOLT
Short Form: LIST:VOLT[:LEV] <exp_value>, <exp_value>, . . . (to max of 1002 data points)
Long Form: LIST:VOLTage[:LEVel] <exp_value>, <exp_value>, . . . (to max of 1002 data points)
<exp_value> = digits with decimal point and Exponent, e.g., 2.71E1 for 27.1
Description:
Adds the voltage value (in Volts) to list.
This command sequentially adds LIST:VOLTage values to
the main channel List Data Table locations illustrated in Table B-2. LIST:CLE sets starting location to 0.
Next location indicated by LIST:VOLT:POIN? These locations correspond to the default sequence
(LIST:GEN DESQ) The maximum number of entries is 1002.
Since the input buffer of the BIT 4886
has a limit of 253 characters, multiple commands are necessary to complete the full 1002 entries of
the list. If LIST:CURR has any entries, an error message: -221,"Settings conflict" is posted in the error
queue. Related Commands: LIST:VOLT:POIN?, FUNC:MODE, LIST:CLE, *RST. (See example, Fig-
ures B-2 and B-3.)
B.46 [SOURce:]LIST:VOLTage? QUERY
LIST:VOLT?
Syntax:
Short Form: LIST:VOLT?
Long Form: LIST:VOLTage?
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 the main channel locations of Table B-2. Related Commands: LIST:
VOLT, LIST:QUERy. If LIST:CURR has any entries, an error message: -221,"Settings conflict" is
posted in the error queue. (See example, Figure B-3.)
B.47 [SOURce:]LIST:VOLTage:POINts? QUERY
LIST:VOLT:POIN?
Syntax:
Short Form: LIST:VOLT:POIN? Long Form: LIST:VOLTage:POINts?
Return Value: <value> (0 to 1001)
Description:
Identifies the total number of points in a list and the next location to be filled by LIST:VOLT
command.
The LIST:VOLT pointer is initially at 0 via *RST or LIST:CLE. For each data point entered
by a LIST:VOLT command the list pointer is incremented If LIST:VOLT:POIN? returns 5, the
LIST:VOLT pointer is at 5 indicating there are 5 data points comprising the list (locations 0 though 4)
and location 5 is the next to be filled. If LIST:CURR has any entries, an error message: -221,"Settings
conflict" is posted in the error queue. Related Commands: LIST:VOLT. (See example, Figure B-3.)
B.48 [SOURce:]CURRent[:LEVel][:IMMediate][:AMPlitude] COMMAND
CURR
Syntax:
Short Form: [SOUR:]CURR[:LEV][:IMM][:AMP] <exp_value>
Long Form: [SOURce:]CURRent[:LEVel][:IMMediate][:AMPlitude] <exp_value>
<exp_value> = digits with decimal point and Exponent, e.g., 2.71E1 for 27.1
Description:
Sets programmed current level at power supply output.
This command programs output current to
a specific value; actual output current will depend on load conditions. If CURR:RANG is set to 4, any
data that exceeds 1/4 of I
MAX
causes error message -222 “data out range” to be posted to the error
queue (See example, Figure B-4.)
B.49 [SOURce:]CURRent[:LEVel][:IMMediate][:AMPlitude] QUERY
CURR?
Syntax:
Short Form: [SOUR:]CURR[:LEV][:IMM][:AMP]? MIN, MAX
Long Form: [SOURce:]CURRent[:LEVel][:IMMediate][:AMPlitude]? MIN, MAX
Return Value:
<exp_value> = digits with decimal point and Exponent, e.g., 2.71E1 for 27.1
Description:
Returns either the programmed value, maximum value, or minimum value of current.
The
CURR? query returns the programmed value of current. Actual output current will depend on load con-
ditions. The CURR?MAX query returns the maximum current allowed for a particular model. CURR?
MIN returns minimum current allowed for power supply (always negative).
