FIGURE B-10. USING PROT:LIM:POS AND PROT:LIM:POS COMMANDS TO SET ASYMMETRICAL LIMITS
B.97 [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 ,
Description: Identifies the protection limits for voltage (positive, negative); maximum is 1% greater than rated out-
put voltage.
B.98 [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.
FIXED - Allows the limits to be controlled by digital commands.
EXTERNAL: Allows the limits to be controlled by analog signals applied to the analog port.SCPI com-
mands have no effect (see PAR. 3.3.6.1).
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 SCPI command. Whichever limit has a
lower absolute value (closest to zero) has effect.
B.99 [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.98 for details).
B.100 [SOURce:]VOLTage[:LEVel]:PROTect:NEGative COMMAND
VOLT:PROT:NEG
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT:NEG
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:NEGative
where 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.101 [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:
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
