Programming Select Sequence to Program

Sequences PROGram:NAME <sequence_number>

<sequence_number> is a number between 1 and 10 that corresponds to the number of the sequence.

Define the name of the program to be selected. If <sequence_number> already exists, then that existing program is selected. If the program name does not exist, then the new name is selected, but no program is defined by this selection.

Editing the Sequence

To edit an existing step or to program new steps, use the following commands: PROG:STEP<step_number>[:EDIT] [[[[[<voltage>]

,<current>],<power>],<OVP_level>],{<time>TRIG}]

Any of the step parameters may be omitted, in which case the default parameters will be used. The defaults are 0 V, 0 A, 0 W, 0 V, 10 ms.

To insert a step between commands in an existing program, use this command: PROG:STEP<step_number>:INS <voltage> ,<current>,<power>,<OVP_level>,{<time>TRIG}

The step number is where the inserted step is to be located. The existing step and all following steps at that location are moved down.

In both the edit and insert commands:

•<step_number> ranges from 1 to 99.

•<time> defines the duration of the step and must be entered in the format milliseconds. It ranges from 10ms to 99 hours.

•TRIG may be entered instead of a step duration. In this case, the unit will hold the output levels at that step until a trigger signal is supplied.

Setting Sequence Repetitions

PROG:REP {ONCE <sequence_count>FORINF}

•ONCE will run the sequence once and return it to its STOP condition.

•<sequence_count> ranges from 1 to 9999. It will run the sequence the number of times specified before putting it into the STOP condition.

•FORever and INFinity cause the sequence to repeat forever. A query will return 9.9E37, representing INFinity.
