[SOURce:]CURRent:MODE COMMAND
CURR:MODE
Syntax:
Short Form: [SOUR:]CURR:MODE (FIX | LIST | TRAN <nn> | EXT | GAIN | PROT)
Long Form: [SOURce:]CURRent:MODE (FIXed | LIST | TRANsient <nn> | EXTernal | GAIN | PROTect)
nn = <value> = time in Seconds for transient (from 0.0005 to 2.0)
Description:
Allows the user to execute or stop a list, to execute a transient or to use an external reference in
voltage or current mode of operation.
The default mode is FIXed: the power supply executes com-
mands 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 CURR:MODE LIST is issued, a list is executed (See LIST commands and Figure B-5). 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.
Issuing CURR:MODE HALT while the list is running will stop the execution of the list at the end of the
current cycle.
CURR:MODE TRAN nn causes the next CURR: or VOLT: command to produce a transient pulse of
nn Seconds duration. (Similar to VOLT:MODE TRAN (see PAR. B.95 for examples). If the time nn
exceeds 2 Seconds, error message -222 “dwell or frequency out range” is posted to the error queue.
CURR:MODE EXT Configures the unit to use an external reference to change the main channel,
whether voltage or current (see PAR. 3.4). Identical to VOLT:MODE EXT.
CURR:MODE GAIN Configures the unit to use an external reference to provide a proportional out-
put current.
CURR:MODE PROT - allows CURR command to accept values up to the protection limits of the
power supply without generating an error. For example for a BOP 36-28MG in current mode, after
sending CURR:MODE PROT, sending CURR 28.3 would set the protection levels to 28.3 and main
channel level to 28.

[SOURce:]CURRent:MODE? QUERY
CURR:MODE?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:MODE?
Long Form: [SOURce:]CURRent[:LEVel]:MODE?
Return value:
FIXED, LIST, TRANSIENT, EXTERNAL or GAIN
Description:
Identifies active current mode.
Returns LIST while list is being executed. Returns TRANSIENT after
CURR:MODE:TRAN command has been issued, but before CURR: or *TRG command executes the
transient. Returns FIXED while in fixed (default) mode of operation. Returns EXT or GAIN when exter-
nal reference is to be used to either program output current or provide proportional output current,
respectively.
Related Commands:
LIST commands. (Similar to VOLT:MODE?, see Figure B-5.)
B.29
[SOURce:]CURRent[:LEVel]:PROTect[:BOTH] COMMAND
CURR:PROT[:BOTH]
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT:BOTH <value>
Long Form: [SOURce:]CURRent[:LEVel]:PROTect:BOTH <value>
where <value> is between minimum (box) value (Figure 1-3) and 1% above rated (nominal) output
current.
Description: Establishes both the positive and negative protection limits for current, the maximum current the unit is
set up to source and sink; maximum is 1% greater than rated output current.

[SOURce:]CURRent[:LEVel]:PROTect[:BOTH] QUERY
CURR:PROT[:BOTH]?
Syntax:
Short Form: [SOUR:]CURR[:LEV]:PROT[:BOTH]?
Long Form: [SOURce:]CURRent[:LEVel]:PROTect[:BOTH]?
Returns <value>, <value>
Description: Identifies the protection limits for current (source, sink), the maximum current the unit will source.or
sink
