FIGURE B-3. USING LIST COMMANDS AND QUERIES (SHEET 2 OF 2)
B.34 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.)
B.35 MEASure:VOLTage[:SCALar][:DC]? QUERY MEAS:VOLT?
Syntax: Short Form: MEAS[:SCAL]:VOLT[:DC]? Long Form: MEASure[:SCALar]:VOLTage[:DC]?
Description: Measures actual voltage. This query returns the actual value of output voltage (measured at the out-
put terminals) as determined by the programmed value of voltage and current and load conditions.
(See example, Figure B-1.)
B.36 OUTPut[:STATe] COMMAND OUTP
Syntax: Short Form: OUTP[:STAT] <boolean> Long Form: OUTPut[:STATe] <boolean>
<boolean>=(0 or OFF, 1 or ON)
Description: Enables or disables the power supply output (see PAR.3.2.7.2 for disabling if analog program-
ming used). Upon power up the output is enabled (OUTP ON). When OUTP OFF is executed, the
digitally programmed values of voltage and current are saved, then voltage and current are pro-
grammed to 0V for voltage and between 3 and 10 LSBs for current; analog programming is not
affected. When OUTP ON is executed, the power supply output is restored to the previously saved
programmed values. The saved values of voltage and current can be viewed by VOLT? and CURR?
queries. Related Commands: OUTP?. (See example, Figure B-1.)
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 -226,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.
LIST: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 19 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 4,2,0,10,0,10.
LIST COUNT 0 List will repeat indefinitely.
VOLT:MODE LIST The list is executed. Staircase wave now consists of 21 steps of 0.01 sec-
onds except for the 20V step (location 10) which outputs 20V for 1 second.
The beginning of the staircase has three steps of 0.1 second.
VOLT:MODE FIX Stops execution of the list
VOLT 4 Programs output to 4V.
