Functions
Basic waveform generation
DOSF is equipped with a built in function generator that produces basic waves such as sine, rectangular and triangle waves.
Frequency range can be set between 1 Hz and 200 kHz. You can adjust amplitude; start phase (for sine wave), on-phase control (for sine wave), and duty ratio (for rectangular/triange wave).
Application
Power activation test, Inrush current measurement, waveform fluctuation test
Sequence functions
The DOSF series is equipped with programmable sequence functions such as step time, step amplitude ramp, ramp, CV/CC mode, frequency sweep, AC superposition, step jump, and jump times. These useful functions help to program the desired waves in very flexible manner, enabling to support efficient laboratory and research works.
If amplifier’ s output turn off while it is running a sequence program half-way-through, the leftover sequence will not run but it is re-activated from the beginning of the original sequence.
- Step time: 10 ms to 1999 s 999 ms (resolution: 1 ms), ramp and AC waveform is 50 ms
- Up to 16 steps can be set and saved plus three programs per program.
- Can be set CV/CC mode per program
- Frequency: Infinite, 1 to 999
Sequence functions help to create complicated waves like below to be simply and easily edited.
Applications
Testing of motors, pulse power supply and various evaluation
Measurement functions
The DOSF series is equipped with programmable sequence functions such as step length, step amplitude ramp, ramp, CV/CC mode, frequency sweep, AC superposition, step jump, and jump times. These useful functions help to program the desired waves in very flexible manner, enabling to support efficient laboratory and research works.
Memory functions
During fundamental wave operation, output voltage (in CV mode), output current (in CC mode), CV/CC setting, and waveform settings can be saved in 10 set-up memories.
As sequence programs can be saved in up to three, it is useful when using frequently used multiple waveforms or sequence operations.
- Other functions:
- DOSF is equipped with a Protection function, Key-lock function, and CV/CC switching, as standard options.
