1.3 Waveforms That Can Be Generated

IM 707281-01E
This module has the following three waveform generation modes. One mode is selected
and the waveform is generated.
DC : DC signal
AG : Arbitrary waveform
FG : Sine wave, pulse wave, ramp wave, triangular wave, arbitrary wave, and DC
signal.
The functional differences between each waveform generation mode are as follows:
DC
Generated waveform Constant voltage output Loaded arbitrary waveform Sine, pulse, ramp,
Arbitrary waveform No

*1 mHz to 20 kHz during sine wave generation.
The differences between the creation and generation of arbitrary waveforms in the AG
mode and in the FG mode are as follows:
AG mode
• Used when outputting pattern waveforms.
• The maximum allowable data length is 4 Mwords/CH (when using 1 CH)
• Data saved by digital oscilloscope and digitizer modules can be used directly.
• Each channel of waveform memory can be divided into multiple blocks and waveform
data can be loaded to the individual blocks.
FG mode
• Used when outputting a constant waveform in units of one cycle.
• The data length is fixed to 64 Kwords.
• The output frequency can be set up to 10 kHz (20 kHz for sine waves).
• The frequency and amplitude can be specified.
• Frequency and amplitude sweeps are possible.
• The offset and phase difference between channels can be specified.
