B.51 [SOURce:]VOLTage:MODe COMMAND
VOLT:MODE
Syntax: Short Form: [SOUR:]VOLT:MODE (FIX | LIST | TRAN) nn
Long Form: [SOURce:]VOLTage:MODE (FIXed | LIST | TRANsient) nn
nn = = time in seconds for transient
Description: Allows the user to execute or stop a list, or to execute a transient. The default mode is FIX: the
power supply executes commands normally, and LIST commands can be issued to establish the
parameters and sequence of a list.
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 (Not supported at this time, contact Kepco for more information).
Related Commands: LIST commands. (See example, Figure B-2.)
B.52 [SOURce:]VOLTage:MODe? QUERY
VOLT:MODE?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:MODE?
Long Form: [SOURce:]VOLTage[:LEVel]:MODE?
Return value: FIXED or LIST or TRAN
Description: Identifies active voltage mode. Returns LIST while list is being executed. TRAN (transient) is not
supported at this time, contact Kepco for more information. Returns FIXED while in fixed (default)
mode of operation. Related Commands: LIST commands. (See example, Figure B-2.)
B.53 [SOURce:]VOLTage:PROTection[:LEVel] COMMAND
VOLT:PROT
Syntax: Short Form: [SOUR:]VOLT:PROT[:LEV]
Long Form: [SOURce:]VOLTage:PROTection[:LEVel]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Sets overvoltage protection level for power supply.If the value is out of the acceptable overvoltage
range for the power supply model, error message -222,"Data out of range" is posted in the output
queue. If the power supply output exceeds the voltage protection level programmed, then the power
supply output is disabled (programmed to 0) and the OV bit in the Questionable Condition status reg-
ister is set. An overvoltage condition can be cleared with the VOLT:PROT:CLE command. The voltage
protection level can be programmed independently of the output voltage level. Setting voltage protec-
tion to a value lower than the output voltage causes the voltage protection mechanism to trigger imme-
diately. (See example, Figure B-5.)
B.54 [SOURce:]VOLTage:PROTection[:LEVel]? QUERY
VOLT:PROT?
Syntax: Short Form: [SOUR:]VOLT:PROT[:LEV] MIN, MAX
Long Form: [SOURce:]VOLTage:PROTection[:LEVel] MIN, MAX
Return Value: = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Identifies overvoltage protection setting, maximum allowable overvoltage protection, or mini-
mum overvoltage protection. VOLT:PROT? returns value set by VOLT:PROT. VOLT:PROT? MAX
returns maximum voltage protection value (see Table 1-2 ); this value is determined at the factory and
cannot be changed by the user. VOLT:PROT? MIN returns the minimum voltage protection value
(always 0). (See example, Figure B-5.)
B.55 [SOURce:]VOLTage:[:LEVel]TRIGgered[:AMPlitude] COMMAND
VOLT:TRIG
Syntax: Short Form: [SOUR:]VOLT[:LEV]:TRIG[:AMP]
Long Form: [SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPlitude]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Programs voltage value to be transferred to output by *TRG commands. Actual output voltage
will depend on load conditions. If the value exceeds the maximum for the model being programmed,
error message -222,”Data out of range” is posted in output queue. If value exceeds VOLT:LIM:HIGH
value, a value corresponding to the voltage limit will be programmed. NOTE: A current trigger must be
entered at least once. (See example, Figure B-1.)
