B.28 [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-5.)
B.29 [SOURce:]CURRent[:LEVel]:PROTect[:BOTH] COMMAND
CURR:PROT[:BOTH]
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT:BOTH <value>
Long Form: [SOURce:]CURRent[:LEVel]:PROTect:BOTH <value>
where <value> is between minimum (box) value (Figure 1-3) and 1% above rated (nominal) output
current.
Description: Establishes both the positive and negative protection limits for current, the maximum current the unit is
set up to source and sink; maximum is 1% greater than rated output current.
B.30 [SOURce:]CURRent[:LEVel]:PROTect[:BOTH] QUERY
CURR:PROT[:BOTH]?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT[:BOTH]?
Long Form: [SOURce:]CURRent[:LEVel]:PROTect[:BOTH]?
Returns <value>, <value>
Description: Identifies the protection limits for current (source, sink), the maximum current the unit will source.or
sink
B.31 [SOURce:]CURRent[:LEVel]:PROTect:MODE COMMAND
CURR:PROT:MODE
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT:MODE (EXT | FIX | LESS |)
Long Form: [SOURce:]CURRent[:LEVel]:PROTect:MODE (EXTernal | FIXed | LESSer |)
Description: Determines how current protection limits are controlled.
FIXED - Allows the limits to be controlled by digital signals from either the keypad (if the unit is in local
mode) or SCPI command (if the unit is in remote mode).
EXTERNAL: Allows the limits to be controlled by analog signals applied to the analog port; limits set
from the keypad or SCPI command have no effect (see PAR. 3.3.6.1).
LESSER LIMIT: Allows protect limit to be automatically selected from either 1) the external analog limit
CURRent applied to the Analog I/O port or 2) the value set from the keypad or SCPI command).
Whichever limit has a lower absolute value (closest to zero) has effect
B.32 [SOURce:]CURRent[:LEVel]:PROTect:MODE? QUERY
CURR:PROT:MODE?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT:MODE?
Long Form: [SOURce:]CURRent[:LEVel]:PROTect:MODE?
Returns FIXED, EXTERNAL or LESS
Description: Identifies how current protection limits are controlled. (See PAR. B.31 for details).
B.33 [SOURce:]CURRent[:LEVel]:PROTect:NEGative COMMAND
CURR:PROT:NEG
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT:NEG <value>
Long Form: [SOURce:]CURRent[:LEVel]:PROTect:NEGative <value>
where <value> is between minimum (box) value (Figure 1-3) and 1% above rated (nominal) output
current.
Description: Establishes the negative protection limit for current, maximum is 1% greater than rated (nominal) out-
put current.
