Output Setting and Operation Commands

Output On/Off and Tracking Operation Commands

OUTPut[:STATe] {OFF | ON}

This command enables or disables all three outputs of the power supply. The

state of the disabled outputs is a condition of less than 0.6 volts of opposite

polarity with no load and less than 60 mA of opposite direction with a short

circuit. At

*RST

, the output state is off.

OUTPut[:STATe]?

This command queries the output state of the power supply. The returned

value is “0” (OFF) or “1” (ON).

OUTPut:TRACk[:STATe] {OFF | ON}

This command enables or disables the power supply to operate in the track

mode. When the track mode is first enabled, the -25V supply will be set to

the same voltage level as the +25V supply. Once enabled, any change of the

programmed voltage level in either +25V supply or -25V supply will be

reflected in the other supply. The

TRACk OFF

command returns the power

supply to the non-track mode. The ±25V supplies must not be coupled to

enable “Track”. At

*RST

, the track mode is disabled.

OUTPut:TRACk[:STATe]?

This command queries the track mode state of the power supply. The

returned value is “0” (OFF) or “1” (ON).

Output Setting Commands

[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]

{<current>|MINimum | MAXimum}

This command directly programs the immediate current level of the power

supply. The immediate level is the current limit value of the output selected

with the

INSTrument

command.

[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]?

[MINimum | MAXimum]

This query returns the presently programmed current limit level of the

selected output.

CURRent?

MAXimum

and

CURRent? MINimum

return

the maximum and minimum programmable current levels of the selected

output.
