SETUP Configuration Commands and Queries
‡
SUPPly:CURRent:MAXimum?
Returns the maximum output current capacity of the power supply in
amperes. This value can only be configured via front panel operation of the
SUPPLY setup menu and is set automatically when a preset supply type is
selected.
‡
SUPPly:MODE?
Returns an integer value corresponding to the voltage output mode
according to the table below:
This value can only be configured via front panel operation of the SUPPLY
setup menu and is set automatically when a preset supply type is selected.
‡
CONFigure:STABility < percent >
Sets the stability setting in percent.
‡
STABility?
Returns the stability setting in percent.
‡
CONFigure:COILconst < value (kG/A, T/A >
Sets the coil constant (also referred to as the field-to-current ratio) per the
selected field units. The coil constant must be set to a non-zero, positive
value in order to command or query the Model 420 in units of field.
‡
COILconst?
Returns the coil constant setting in kG/A or T/A per the selected field
units.
‡
CONFigure:CURRent:LIMit < current >
Sets the magnet current limit in amperes. The current limit is the largest
magnitude operating current allowed during any ramping mode. For four-
quadrant power supplies, the current limit functions as both a positive and
negative current limit.
