4.5 Sequence Operation
4.5.1 Sequence operation specifications
The BP4610 allows the output voltage and output current to be freely programmed using the sequence
function.
In addition to basic oscillation, the sequence function can be used as the signal source of the power
supply for specification testing, such as power supply environment testing and automotive electronics
testing. For example, by programming in advance a series of voltage change patterns for use in voltage
variation testing for electrical equipment, the output can be cycled through variations according to a
preset sequence, allowing testing to be completed through a single operation.
The BP4610’s internal DC (direct current), sine wave, square wave, or any of 16 arbitrary waveforms
loaded via the USB interface can be used for the sequence operation. The sequence can be set to up to
255 steps (1 step = 0.1 ms minimum), and the waveform, level, duration, and constant/sweep settings
can be selected individually for each step. Moreover, repetition of the sequence can be specified
between 1 to 1000 times (or continuous).
Additional functions including branch operation, which causes the operation to go to the specified step
during sequence operation, sequence start, stop, and hold, are also provided.
Number of sequences: 1 sequence each for the CV mode and CC mode
Number of steps: 1 to 255 (within 1 sequence)
Step time: 0.1 ms to 999.9999 s (resolution: 0.1 ms)
Operation within step: Constant or linear sweep
Parameters: CV mode: DC voltage, superimposed AC voltage, frequency,
waveform, step sync output (2-bit)
CC mode: DC current, superimposed AC current, frequency, waveform,
step sync output (2-bit)
Remark: If a sine wave or square wave is selected as the waveform,
the waveform cannot be changed during the sequence.
If arbitrary waveform is selected, an arbitrary wave can be
specified for each step.
Jump count: 1 to 999, or continuous
Sequence control: Start: Starts sequence.
Stop: Stops sequence.
Hold: Maintains settings at that point in time. The operation
resumes at sequence start.
Branch: Branches to the specified step.
