B.37 [SOURce:]CURRent:LIMit:HIGH COMMAND
CURR:LIM:HIGH
Syntax: Short Form: [SOUR:]CURR:LIM:HIGH
Long Form: [SOURce:]CURRent:LIMit:HIGH
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Sets Virtual Model maximum programmable limit for power supply output current (see PAR.
3.2.5). If the value is out of the acceptable current range for the power supply model, error message
-222,"Data out of range" is posted in the output queue. If the user tries to set an output current value
larger than the CURR:LIM:HIGH setting, a value corresponding to the current limit will be programmed
and error message -301,"Value bigger than limit" is posted in the output queue. Once the limit is
established, the unit will not allow values higher than the programmed limit. NOTE: If the Virtual Model
maximum programmable current limit is changed, previously stored trigger levels, (PAR. B.43), stored
settings (PAR. A.11) or programmed sequences using the LIST commands may be outside the range
established by the new virtual model. In this case, prior to execution, the value is cleared to the default
minimum (minimum A) and an “out of range” error message is generated. This command is password
protected, requires SYST:PASS:CEN prior to execution. Related Commands: CURR,
SYST:PASS:CEN. (See example, Figure B-3.)
B.38 [SOURce:]CURRent:LIMit:HIGH? QUERY
CURR:LIM:HIGH?
Syntax: Short Form: [SOUR:]CURR:LIM:HIGH? Long Form: [SOURce:]CURRent:LIMit:HIGH?
Return Value: = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Returns value representing Virtual Model current limit set by CURR:LIM:HIGH command.
Related Commands: CURR:LIM:HIGH, CURR. (See example, Figure B-3.)
B.39 [SOURce:]CURRent:MODE COMMAND
CURR:MODE
Syntax: Short Form: [SOUR:]CURR:MODE (FIX | LIST | TRAN) nn
Long Form: [SOURce:]CURRent: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 CURR: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 CURR: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.
CURR:MODE TRAN nn (Not supported at this time, contact Kepco for more information).
Related Commands: LIST commands. (See example, Figure B-2.)
B.40 [SOURce:]CURRent:MODE? QUERY
CURR:MODE?
Syntax: Short Form: [SOUR:]CURR[:LEV]:MODE?
Long Form: [SOURce:]CURRent[: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.)
