1.7. OUTPut Subsystem

1.7.1. OUTPut?

This query returns the output state of the power supply. A 1 indicates the product’s power processing circuit is active and processing power, while and a 0 indicates the power supply is in standby or faulted state.

Query Syntax:

OUTPut[:STATe]?

Examples:

OUTP?

Return Param:

0 | 1

1.7.2. OUTPut:ARM

This command selects between fixed programmed set points and auto sequence mode. Fixed programmed set points energizes the product to voltage and current settings until the product is stopped. Auto sequence mode sequentially steps through the memory states, updating the supply’s set points at user defined increments. Each memory location contains the voltage set point, current set point, over voltage trip, over current trip, and period. The period parameter, in milliseconds, specifies the time period for operating at the memory location when auto sequence operation is active. When enabled, the ARM light lights on the front panel.

To initiate a program sequence, select the starting memory location, execute this command, and issue an OUTP:START command or use the front panel start switch. The ARM light will blink after the start command. If this process reaches the upper memory limit, memory location 99, the following memory location will revert back to 0 and continue. Auto sequence operation will continue until an OUTP:STOP is commanded or a memory location with period set to 0 is encountered.

ARM? returns the ARM status of the power supply unit (i.e. whether ARM is enabled or disabled).

Note

The OUTPut:ARM command is only available on TS Series and MT Series products with the D Version front panel.

Command Syntax:

OUTP:ARM <bool>

Parameters:

0 (OFF) | 1 (ON)

Examples:

OUTP:ARM OFF, OUTP:ARM 1

Query Syntax:

OUTP:ARM

Return Param:

0 | 1

1.7.3. OUTPut:START

This command closes the power supply’s input contactor and initiates either normal or auto sequence mode. Auto sequence mode will be initiated if the ARM option is enabled. Normal mode energizes the power supply with the current parameters for voltage set point, current set point, over voltage trip, and over current trip. Auto sequence mode will sequentially step through memory locations until the stop is commanded, OUTP:STOP, or a terminating condition is reached (see PERiod and OUTPut:STOP).

Command Syntax:

OUTP:START

Examples:

OUTP:START, OUTPut:START

1.7.4. OUTPut:STOP

This command opens the power supply’s input contactor and disables the power processing circuitry, stopping output and returning the power supply to standby. If an auto sequence is in progress, it is terminated.

Command Syntax:

OUTP:STOP

Examples:

OUTP:STOP, OUTPut:STOP

1.7.5. OUTPut:PROTection:CLEar

This command clears the alarm latches. There are seven alarm latches, namely: interlock, program line, phase loss, thermal, over voltage trip, over current trip, and fuse. Phase loss is not available on SL Series; fuse is available on TS Series and MT Series only. When a fault is detected, the power supply is rendered to an alarm state. The power supply cannot be restarted until the protection condition is cleared and the latch is reset.

Command Syntax:

OUTPut:PROTection:CLEar

Examples:

OUTP:PROT:CLE, OUTPUT:PROTection:CLEar
