B.46 [SOURce:]CURRent[:LEVel]:LIMit::NEG? QUERY
CURR:LIM:NEG?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:LIM:NEG?
Long Form: [SOURce:]CURRent[:LEVel]:LIMit:NEGative?
Returns
Description: Identifies the negative software limit value of output current that the unit can source (quadrant 3, Fig-
ure 1-2) or sink (quadrant 2).
B.47 [SOURce:]CURRent[:LEVel]:LIMit::POS COMMAND
CURR:LIM:POS
Syntax:
Short Form: [SOUR:]CURR[:LEV]:LIM:POS
Long Form: [SOURce:]CURRent[:LEVel]:LIMit:POSitive
where
Description: Establishes the positive software limit
put current that the unit will be allowed to source (quadrant 1, Figure 1-2) or sink (quadrant 4) to the
value specified by the user. Requires MEM:UPD (PAR. B.11) to save for power up. See PAR. 3.5.2.2
and Figure 3-16 for special programming considerations.
B.48 [SOURce:]CURRent[:LEVel]:LIMit::POS? QUERY
CURR:LIM:POS?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:LIM:POS?
Long Form: [SOURce:]CURRent[:LEVel]:LIMit:Positive?
Returns
Description: Identifies the positive software limit value of output current that the unit can source (quadrant 1, Figure
1-2) or sink (quadrant 4).
B.49 [SOURce:]CURRent:MODE COMMAND
CURR:MODE
Syntax:
Short Form: [SOUR:]CURR:MODE (FIX | LIST | TRAN
Long Form: [SOURce:]CURRent:MODE (FIXed | LIST | TRANsient
nn =
Description: Allows the user to execute or stop a list, to execute a transient or to use an external reference.
The default mode is FIXed: the power supply executes commands normally, and LIST commands can
be issued to establish the parameters and sequence of a list. This command affects the main channel,
whether voltage or current.
When CURR:MODE LIST is issued, a list is executed (See LIST commands and Figure B-2). While
the list is being executed, LIST commands are not accepted and will produce a command error.
Issuing CURR:MODE FIX while the list is running will stop the execution of the list and return power
supply to settings in effect prior to running the list. If the list runs to completion, the settings of the last
step of the list will be in effect.
CURR:MODE TRAN nn causes the next CURR: or VOLT: command to produce a transient pulse of
nn seconds duration. (Similar to VOLT:MODE TRAN (see PAR. B.75 for examples). If the time nn
exceeds 1 second, error message -222 “dwell or frequency out range” is posted to the error queue.
CURR:MODE EXT Configures the unit to use an external reference to change the output current.
CURR:MODE GAIN Configures the unit to use an external reference to provide a proportional out-
put current.
Related Commands: LIST commands. (See example, Figure B-2.)
B.50 [SOURce:]CURRent:MODE? QUERY
CURR:MODE?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:MODE?
Long Form: [SOURce:]CURRent[:LEVel]:MODE?
Return value: FIXED, LIST, TRANSIENT, EXTERNAL or GAIN
Description: Identifies active current mode. Returns LIST while list is being executed. Returns TRANSIENT after
CURR:MODE:TRAN command has been issued, but before CURR: or *TRG command executes the
transient. Returns FIXED while in fixed (default) mode of operation. Returns EXT or GAIN when exter-
nal reference is to be used to either program output current or provide proportional output current,
respectively. Related Commands: LIST commands. (Similar to VOLT:MODE?, see Figure B-2.)
