B.24 [SOURce:]LIST:QUERY COMMAND
LIST:QUER
Syntax: Short Form: LIST:QUER <int_value>
Long Form: LIST:QUERy <int_value>
int_value = 0 to 1001
Description: Determines first location to be queried by LIST:SEQ? query. Related Commands: LIST:SEQ?.
LIST:QUER?. (See example, Figure B-2.)
B.25 [SOURce:]LIST:QUERY? QUERY
LIST:QUER?
Syntax: Short Form: LIST:SEQ? Long Form: LIST:SEQuence?
Return Value: <int_value>
Description: Identifies first location to be queried by LIST:SEQ?, LIST:VOLT?, LIST:CURR?, LIST:DWEL?
queries. Related Commands: LIST:QUER, LIST:SEQ. (See example, Figure B-2.)
B.26 [SOURce:]LIST:VOLTage COMMAND
LIST:VOLT
Short Form: LIST:VOLT[:LEV] <exp_value>, <exp_value>, . . . (to max of 100 data points)
Long Form: LIST:VOLTage[:LEVel] <exp_value>, <exp_value>, . . . (to max of 100 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. LIST:CLE sets starting location to 0. Next location indi-
cated by LIST:VOLT:POIN? The maximum number of entries is 100. Since the input buffer of the KLP
has a limit of 253 characters, multiple commands are necessary to complete the full 100 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?, LIST:CLE, *RST. (See example, Figure B-2.)
B.27 [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:QUER, returns comma-separated list of up to 16 values indicating the main channel parameters
entered. i.e., the contents of the main channel List Data Table. Related Commands: LIST: VOLT,
LIST:QUER. If LIST:CURR has any entries, an error message: -221,"Settings conflict" is posted in the
error queue. (See example, Figure B-2.)
B.28 [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-2.)
B.29 MEASure[:SCALar]:CURRent[:DC]? QUERY
MEAS:CURR?
Syntax: Short Form: MEAS[:SCAL]:CURR[:DC]? Long Form: MEASure[:SCALar]:CURRent[:DC]?
Return Value: <num_value> (digits with decimal point and Exponent)
Description: Measures actual current. This query returns the actual value of output current (measured at the out-
put terminals) as determined by the programmed value of voltage and current and load conditions.
(See example, Figure B-1.) NOTE: The SCPI convention for this command allows the controller to
establish the range and accuracy of the measurement if nn,nn is added after the question mark; the
KLP accepts this format but sets the command warning bit (13) in the status questionable register and
ignores the extra characters.
