CC Load/CV Load
The CC Load emulates a constant-current load. The CV Load
emulates a constant-voltage load. The figures below show the CC and
CV load settings.
In CC load mode you can specify the input Current and Range as well
as the + Voltage Limit. Current Priority mode is locked. Remember to
set the input current to a negative value. The + Voltage Limit should
normally be set to its maximum value. The – Voltage limit is not
programmable. In Meter mode, the measurement polarities and
current settings are shown as negative values.
In CV load mode you can specify the input Voltage and Range as well
as the – Current Limit. Voltage Priority mode is locked. Set the input
voltage to a positive value. The – Current Limit should normally be
set to its maximum negative value. The + Current Limit is not
programmable. In Meter mode, the measurement polarities and
current settings are shown as negative values.
From the remote interface:
To specify the 4-quadrant, 2-quadrant, or 1-quadrant power supply
emulation setting:
EMUL PS4Q,(@1)
EMUL PS2Q,(@1)
EMUL PS1Q,(@1)
To set the voltage priority mode:
FUNC VOLT,(@1)
To set the output voltage to 5 V and the low voltage range:
VOLT 5,(@1)
RANG 6,(@1)
To set the positive current limit of output 1 to 1 A:
CURR:LIM 1,(@1)
To set the negative current limit, you must first turn limit coupling
(tracking) off. Then set the negative current limit to 0.5 A:
CURR:LIM:COUP OFF,(@1)
CURR:LIM:NEG 0.5,(@1)
