6.3 Command Descriptions
APS-1102 Programmable AC/DC Power Source 6-19
 [SOURce:]SEQuence:COUNt?
This returns the jump times of the step specified by SEQ:STEP. The step jump times response
ranges from
1 to 999. 1 is returned in the idle mode.
Syntax: [SOURce:]SEQuence:COUNt?
Parameters: None
Query example: SEQ:COUN?
Response format:
Response example: 2
 [SOURce:]SEQuence:DELete
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 voltage range (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.)
Syntax: [SOURce:]SEQuence:DELete
Parameters: 1
Command example: SEQ:DEL 1
Response format: None
Response example: None
 [SOURce:]SEQuence:EPARameter
This sets the step execution parameters.
The target sequence step must be already set by the SEQ:STEP. (
See
“[SOURce:]SEQuence:STEP” on page 6-22.)
However, the first parameter (DC voltage) and second parameter (DC voltage 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 waveform (ARB)
it is Vp-p.
When in AC-EXT, AC-ADD, AC-SYNC, AC+DC-EXT, AC+DC-ADD, or AC+DC-SYNC mode,
step execution parameters cannot be set or queried. ([3, “Invalid in this mode”] error occurs.)
