Maximum 30MHz, easily outputting the necessary waveforms, improving test efficiency
The oscillation frequency ranges from 0 to a maximum of 30MHz, enhancing test reproducibility with low-distortion, high-quality waveforms. In addition to the main output, it features a sub-output that can independently output waveforms, a wide variety of output waveforms including double pulses used for power device evaluation, numerous oscillation modes, and sequence functions to support waveform output.

■ Sub-output function
The sub-output can independently output a continuous signal separate from the main output. It is capable of outputting two channels worth of frequency, waveform, phase, amplitude, and DC offset, even with a single-channel device. Moreover, when using the internal modulation function with the main output, the sub-output can output the modulated waveform. With such versatile settings, which are surprising for a sub-output, one FG (Function Generator) can be effectively utilized as a multi-phase signal generator.
■Parameter-variable waveforms
Typical waveforms such as power supply-related and pulse wave-related are pre-installed. One example is attenuated waveform vibration waveform. It is also possible to freely edit the vibration frequency and time constant while viewing the output.
■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.
Easily create square waves with overshoot and ringing by using the built-in 2nd order LPF waveform as a parameter-variable waveform.
■Auto range: 20Vp-p/4Vp-p/0.8Vp-p
The output voltage range has three settings: 20Vp-p, 4Vp-p, and 0.8Vp-p. It can automatically output in the range closest to the set voltage. With this feature, it is possible to provide an output with low noise even at lower output voltages.
■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.
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
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.
■Upper and lower limit function
Limiting the set value prevents excessive output due to operational errors. Range limit settings for frequency, positive and negative peaks of voltage, phase, and duty are possible.
