There are one channel (FG410) and two channel (FG420) models. As the output channels are isolated, an FG400 can also be used in the development of floating circuits.

Waveforms can be selected from the displayed list. Waveforms can be created in the FG400 or with the editor software.

Trouble shooting Generation is made easier as the FG400 can generate Acquisition waveforms that are difficult to reproduce. For example noise that only occurs on site. With the XviewerLITE software (freeware), waveform (binary data) that is acquired using a YOKOGAWA DL850E or DLM4000 can be analyzed on the PC to find the abnormal waveform. This abnormal part can then be clipped, saved and generated using the FG400. addition <"QQMJDBUJPO> $MJQQJOHUIFBCOPSNBMTJHOBM UIFOBEEJOHJU UPUIFOPSNBMTJHOBM Connect the clipped abnormal signal output of channel 2 to the additional input terminal of channel 1, and then press the Manual trigger key. The abnormal signal is added to the normal pulse waveform that is set on channel 1. Features and benefits FG400 Series Features and CFOFýUT Application-specific waveforms are also standard 4 1BSBNFUFS7BSJBCMF8BWFGPSNT In some cases engineers need application-specific waveforms like those needed to evaluate the response characteristics of mechanical/ electrical circuits and to emulate power supply circuits. The FG400 provides 25 different types of waveform as standard. As the parameters of application-specific waveforms can be changed like those of basic waveforms, waveforms are quicker and easier to generate.
