B.22 [SOURce:]FUNCtion:MODE COMMAND
FUNC:MODE
Syntax:
Short Form: FUNC:MODE {VOLT | CURR} Long Form: [SOURce:]FUNCtion:MODE {VOLT | CURR}
Description:
Establishes the operating mode of the power supply.
VOLT = Voltage mode. CURR = Current
mode. FUNC:MODE VOLT commands power supply to Voltage mode, FUNC:MODE CURR com-
mands power supply to Current mode. Commanded mode establishes parameters (voltage or current)
monitored for error conditions. Actual mode depends upon load conditions. When commanded to Volt-
age mode, if load conditions cause the power supply to try to exceed the current limit, the unit will flag
an error condition. When commanded to Current mode, if load conditions cause the power supply to
try to exceed the voltage limit, the unit will flag an error condition. If VOLT:MODE or CURR:MODE is
set to TRANS, FUNC:MODE command automatically changes the mode to FIXed. (See example, Fig-
ure B-4.)
B.23 [SOURce:]FUNCtion:MODE? QUERY
FUNC:MODE?
Syntax:
Short Form: FUNC:MODE?
Long Form: [SOURce:]FUNCtion:MODE?
Return value:
0 (voltage mode) or 1 (current mode)
Description:
Returns the operating mode of the power supply.
0 = Voltage mode. 1 = Current mode.
B.24 [SOURce:]FUNCtion:MODE:TRIGger
FUNC:MODE:TRIG
Syntax:
Short Form: FUNC:MODE:TRIG {VOLT | CURR}
Long Form: [SOURce:]FUNCtion:MODE:TRIGger {VOLT | CURR}
Description:
Establishes the operating mode of the power supply when a TRIGger command is sent.
VOLT =
Voltage mode. CURR = Current mode. This command establishes the operating mode for triggers
which is to be saved or recalled using *SAV or *RCL command. FUNC:MODE:TRIG VOLT commands
power supply to Voltage mode when a TRIGger command is sent, FUNC:MODE:TRIG CURR com-
mands power supply to Current mode when a TRIGger command is sent. If VOLT:MODE or
CURR:MODE is set to TRANS, FUNC:MODE:TRIG command automatically changes the mode to
FIXed. (See example, Figure B-5.)
B.25 [SOURce:]FUNCtion:MODE:TRIGger? QUERY
FUNC:MODE:TRIG?
Syntax:
Short Form: FUNC:MODE:TRIG?
Long Form: [SOURce:]FUNCtion:MODE:TRIGger?
Return value:
0 = voltage mode or 1 = current mode
Description:
Returns the operating mode which the power supply will enter when a trigger command is
sent.
VOLT = Voltage mode. CURR = Current mode. (See example, Figure B-5.)
B.26 [SOURce:]LIST:CLEar COMMAND
LIST:CLE
Syntax:
Short Form: LIST:CLE
Long Form: LIST:CLEar>
Description:
Clears all list entries by setting all pointers to 0.
Also sets LIST:DIR to UP, LIST:GEN to DSEQ,
Related Commands: All LIST commands (See example, Figures B-2 and B-3.)
B.27 [SOURce:]LIST:COUNt COMMAND
LIST:COUN
Syntax:
Short Form: LIST:COUN<int_value 0 to 255> Long Form: LIST:COUNt> <int_value 0 to 255>
Description:
Establishes how many times the list is executed.
Allows user to establish how many times the list
(established by LIST:GEN DSEQ or LIST:GEN SEQ and LIST:SEQ) is executed. The order (from
beginning to end or from end to beginning) is determined by LIST:DIR. For LIST:COUN 0, the unit will
execute the sequence indefinitely until either a VOLT:MODE FIXED, or PROG:STOP command is
received. Commands: LIST:GEN, LIST:SEQ, LIST:DIR. (See example, Figures B-2 and B-3.)
B.28 [SOURce:]LIST:COUNt? QUERY
LIST:COUN?
Syntax:
Short Form: LIST:COUNT?
Long Form: LIST:COUNt?
Return Value: <int_value>
Description:
Identifies how many times the list will be executed.
Returns value set by LIST:COUN command.
(See example, Figure B-3.)
