Sub-output function
Equipped with a sub-output. Independent frequency, waveform, phase, amplitude and DC offset. 1CH model can be used as 2CH model. (Sub-output has a maximum amplitude ±3.3V). For differential output application like using two outputs at the same time. WF1981/WF1983 as a 2CH model, WF1982/WF1984 as a 4CH model
Parameter-variable waveforms
Typical waveforms such as power supply related and pulse wave related are pre-installed. One example, Attenuated waveform vibration waveform. It is also possible to freely edit the vibration frequency and time constant while viewing the output.
Double pulse for power device evaluation
Double pulse waveform used for evaluating switching power devices response such as SiC.
Damped vibration
Damped vibration waveform whose amplitude decreases with time, such as a transient response.
Pulse edge variable function
Waveforms can be edited, such as adding overshoots to rising/falling pulse transitions. In addition to general straight lines, cosine and arbitrary waveforms can also be set.
Sequence function
Parameters such as waveform, frequency and amplitude can be set and output sequentially. Complex waveforms can be generated with a maximum of 1023 steps. Sequence editing can be easily done with the control software provided for download.
High-speed, large-capacity arbitrary waveform
Complex waveforms can be output with a long memory of up to 64 Mi words/waveform (WF1983/WF1984) and 32 Mi (WF1981/WF1982). Total capacity Approx. 4Gi words, sampling up to 240M samples/sec. Arbitrary waveform creating can be easily done with the control software provided for download.
2-channel mode (2CH model only)
In addition to using 2 channels independently, various settings such as 2-phase, differential, constant frequency, and constant frequency ratio are possible.
Syncrator function
For waveform conversion of external signals. Output synchronized with externally input signal is possible. The division ratio/multiplication ratio, waveform, phase difference, etc. are also changeable.
