B.114 [SOURce:]VOLTage[:LEVel]:PROTect[:BOTH]? QUERY
VOLT:PROT[:BOTH]?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT[:BOTH]?
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect[:BOTH]?
Returns <exp_value>,<exp_value>
Description: Identifies the protection limits for voltage (positive, negative); maximum is 1% greater than rated out-
put voltage.

B.115 [SOURce:]VOLTage[:LEVel]:PROTect:MODE COMMAND
VOLT:PROT:MODE
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT:MODE (EXT | FIX | LESS |)
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:MODE (EXTernal | FIXed | LESSer |)
Description:Determines how voltage protection limits are controlled in voltage or current mode of oper-
ation.
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 both current and voltage 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. 3.4.5).
LESSER LIMIT: Allows protect limit to be automatically selected from either 1) the external analog
voltage applied to the Analog I/O port or 2) the value set from the keypad or SCPI command). Which-
ever limit has a lower absolute value (closest to zero) has effect
B.116 [SOURce:]VOLTage[:LEVel]:PROTect:MODE? QUERY
VOLT:PROT:MODE?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT:MODE?
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:MODE?
Returns FIX, EXT or LESS
Description: Identifies how voltage protection limits are controlled: FIX for Fixed, EXT for external, LESS for the
lesser of the internal (fixed) and external protection limit values (See PAR. B.115 for details).
B.117 [SOURce:]VOLTage[:LEVel]:PROTect:NEGative COMMAND
VOLT:PROT:NEG
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT:NEG <exp_value>
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:NEGative <exp_value>
where <value> is between minimum (box) value (Figure 1-3) and 1% above rated (nominal) output
voltage.
Description: Establishes the negative protection limit for voltage; maximum is 1% greater than rated output voltage.
B.118 [SOURce:]VOLTage[:LEVel]:PROTect:NEGative? QUERY
VOLT:PROT:NEG?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT:NEG?
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:NEGative?
Returns: <exp_value>
Description: Identifies the negative protection limit for voltage.
NOTE: The power supply is assumed to be operating in constant voltage mode.
VOLT:PROTECT:LIMIT:POS 5 Sets positive voltage protection limit to +5V.
VOLT:PROTECT:LIMIT:NEG 15 Sets negative voltage protection limit to -15V.
VOLT:PROTECT 10 Attempts to set voltage protection levels to ±10V. No error generated.
VOLT:PROT:POS? Returns 5 (positive voltage protection set to +5V since 5 is less than
10.
VOLT:PROT:NEG? Returns 10 (negative voltage protection set to -10V.
VOLT:PROTECT 18 Sets both voltage protection limits to +18V. No error generated.
VOLT:PROT:POS? Returns 5 (positive voltage protection set to +5V since 5 is less than
18.
VOLT:PROT:NEG? Returns 15 (negative voltage protection set to -15V, since 15 is less
than 18
