B.72 [SOURce:]VOLTage[:LEVel]:LIMit:NEGative? QUERY
VOLT:LIM:NEG?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:LIM:NEG? <value>
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:NEGative? <value>
Description: Identifies the software limit value for negative output voltage specified by the user.
B.73 [SOURce:]VOLTage[:LEVel]:LIMit:POSitive COMMAND
VOLT:LIM:POS
Syntax: Short Form: [SOUR:]VOLT[:LEV]:LIM:POS <value>
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:POSitive <value>
where <value> is between zero and rated (nominal) output voltage
Description: Establishes the software limit <value> for positive output voltage, i.e., sets the maximum value of pos-
itive output voltage that the unit will be allowed to produce. 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.74 [SOURce:]VOLTage[:LEVel]:LIMit:POSitive? QUERY
VOLT:LIM:POS?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:LIM:POS? <value>
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:POSitive? <value>
Description: Identifies the software limit value for positive output voltage specified by the user.
B.75 [SOURce:]VOLTage:MODE COMMAND
VOLT:MODE
Syntax: Short Form: [SOUR:]VOLT:MODE (FIX | LIST | TRAN <nn> | EXT | GAIN)
Long Form: [SOURce:]VOLTage:MODE (FIXed | LIST | TRANsient <nn> | EXTernal | GAIN)
nn = <value> = time in seconds for transient (from 0.035 to 1)
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 VOLT: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
VOLT: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.
VOLT:MODE TRAN nn causes the next VOLT: or CURR: command to produce a transient pulse of
nn seconds duration, after which the voltage goes to zero. E.g., VOLT:25 sets the output to 25 volts, and
VOLT:MODE TRAN 0.1 primes the unit for a transient of 0.1 seconds. When VOLT:10 is issued, the
power supply output goes to 10V for 0.1 seconds. Similarly, sending VOLT:TRIG 14, VOLT:MODE
TRAN .05 and *TRG causes the output to go to 14V for 0.05 seconds. If the time nn exceeds 1 second,
error message -222 “dwell or frequency out range” is posted to the error queue.
VOLT:MODE EXT Configures the unit to use an external reference to change the output voltage;
±10V reference produces output = ±Eo (rated) (Fixed gain = Eo (rated).
VOLT:MODE GAIN Configures the unit to use an external reference to provide a proportional output
voltage.
Related Commands: LIST commands. (See example, Figure B-2.)
B.76 [SOURce:]VOLTage:MODE? QUERY
VOLT:MODE?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:MODE?
Long Form: [SOURce:]VOLTage[:LEVel]:MODE?
Return value: FIX, LIST, TRANS, EXT, or GAIN
Description: Identifies active voltage mode. See PAR. B.75 for further details Related Commands: LIST com-
mands. (See example, Figure B-2.)
B.77 [SOURce:]VOLTage[:LEVel]:PROTect:BOTH COMMAND
VOLT:PROT[:BOTH]
Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT[:BOTH] <value>
Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:[BOTH] <value>
where <value> is bewteen minimum (box) value (Figure 1-2) and 1% above rated (nominal) output
voltage.
Description: Establishes the both the positive and negative protection limits for voltage.
