• Frequencies from 1 µHz to 15 MHz
• Frequency range:
  1 μHz to 15 MHz (Sine, Square)
  1 μHz to 200 kHz (Triangle, Pulse, Arbitrary waveform)
  High resolution:
  1 μHz or 9 digits max

• Arbitrary sweep patterns (FG310/FG320)
  You define the waveforms by entering points within the scaled ranges for the X (time) and Y (parameter) axes. The waveform can be generated using linear, step, or spline interpolation between the points. Moreover, you can load the data in ASCII format from an MS-DOS floppy disko you can set up the data in Excel or the spreadsheet of your choice. You can use arbitrary waveforms thus defined as output waveforms or as sweep patterns.

• Load and modify waveforms from other instruments (FG310/FG320)
  You can also use the floppy interface to load waveforms created with YOKOGAWA AG Series arbitrary waveform generators, or captured with YOKOGAWA digital oscilloscopes such as the DL4100, or DL5140/DL5180. You can then either output them as is, or, with the FG300 Series, make further modifications before use.

• Versatile sweep and modulation functions
  With these instruments you can sweep not only frequency, but also other parameters as well, such as phase, amplitude, offset voltage, or duty cycle, with linear, log, linear step, log step, or arbitrary (FG310/FG320) sweep patterns. You can even sweep frequency and amplitude at the same time. Modulation capabilities include not only AM/FM, but also DSB-AM, phase modulation (PM), offset modulation, and PWM. The modulation waveform can be sine or triangle (with variable symmetry), pulse, (with variable duty cycle), or an arbitrary user-defined waveform (FG310/FG320).

• External sweep control (/R1 option)
  Although these are digital function generators, you can still control the sweep parameters with an external analog signal. You can also control them directly with external digital signals. And you enjoy the high accuracy and repeatability that you can only get with digital technologies.

• Amplitude and duty cycle
  With the FG200/FG300 Series, the output signal is not disrupted even if you continuously vary a parameter such as frequency, phase, amplitude, offset voltage, or duty cycle. Duty cycle setting range is 0% to 100%, with 0.01% resolution.

• Multichannel output via synchronized operationBy linking multiple units in parallel with the accessory connecting cables, you can obtain three or even more channels of phase-synchronized signals, and even synchronize the sweep.

• Up to 256 programmed sequence steps (FG310/FG320)
  The sequencing function lets you define sets of parameters for the frequency, phase, amplitude, offset voltage, and duty cycle and select them sequentially via trigger events. You can also specify sets of parameters directly with external digital control signals (with the /R1 option).
