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
Long Form: [SOURce:]CURRent[:LEVel]:PROTect:BOTH
where 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.

CURR:PROT[:BOTH]?

Syntax:

Short Form: [SOUR:]CURR[:LEV]:PROT[:BOTH]?
Long Form: [SOURce:]CURRent[:LEVel]:PROTect[:BOTH]?
Returns ,

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).

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).
