Sequence Step
This outputs the step number being executed.
GW APS-1102 SOUR Seq Len.vi
This returns the maximum number of sequence steps. 255 is always returned.
Max Step
This outputs the maximum step count.
GW APS-1102 SOUR Seq Coun.vi
This returns the jump times of the step specified by SEQ:STEP. –1 is returned in the Idle mode.
Sequence Count
This returns and outputs the step number being executed.
GW APS-1102 SOUR Seq Delete.vi
This clears the sequence memory. When this command is executed, all sequence step settings are
cleared.
However, the sequence memory contains a separate sequence for each operation mode (AC and
AC+DC) and each output (100 V and 200 V), for a total of four combined sets. When sequence
memory is cleared by this command, only one of these four sets is selected as the memory.
When in AC-EXT, AC-SYNC, AC+DC-EXT or AC+DC-SYNC mode, sequence memory cannot be
cleared. ([3,"Invalid in this mode"] error occurs.)
GW APS-1102 SOUR Seq Epar.vi
This sets the step execution parameters. The target sequence step must be already set by the
SEQ:STEP.
However, the first parameter (DC voltage) and second parameter (DC current operation type) are
valid only during AC+DC mode. When in AC mode, dummy values should be set. A “0” is returned
for each of these parameters when in AC mode.
The unit of the third parameter varies depending on the waveform set by the seventh parameter. For
the sine wave (SIN) and square wave (SQU), it is Vrms, and for the arbitrary wave (ARB) it is Vp-p.
