4.4 Using the Sequence Function
4.4.1 Sequence operations
When the sequence function of the APS-1102A is used, the pattern to be output can be freely
programmed.
For example, if a series of voltage change patterns that will be used in voltage variation tests for car
electronics are programmed in advance, the output will change according to the sequence, so the test can
be completed in one series of operations.
In the sequence operation programming, DC, sine waves, and square waves, which are built in the
APS-1102A, and arbitrary waveform (16 types) captured via the USB interface is able to use. Maximum
step number is 255 (minimum step time is 0.1 ms). In each step, waveform, level, and duration time can be
set and constant/keep/sweep can be chosen. In addition, sequences can be repeated from 1 to 999 times (or
continuously). The APS-1102A is also equipped with other functions, such as for branching to a specified
step during a sequence operation, and for starting, stopping, or holding a sequence operation.
Data is saved to sequence memory automatically.
These sequence functions can be used in AC-INT mode or AC+DC-INT mode.
Number of sequences: Retained for each operation mode (AC/AC+DC) and each output voltage
range (100 V/200 V).
Number of steps: 1 to 255 (per sequence)
Step time: 0.1 ms to 999.9999 s (resolution 0.1 ms or 0.0001 s)
Operations within step: Constant, keep, or linear sweep
Parameter: DC voltage
Note
, AC voltage
Note
, frequency, waveform, phase (start, end), step
synchronized output (2 bits)
Jump times: 1 to 999 or infinite
Sequence control: Start: Starts a sequence.
Stop: Stops a sequence.
Hold: Maintains current settings. This is restarted when a
sequence is started.
Branch: Branches to the specified step.
Note The setting ranges for AC voltage and DC voltage are determined by the output voltage ranges
set when editing the sequence data.
Sequence control cannot be executed when the output is off.
