1. OVERVIEW
1.1 Features
The FG410 and FG420 are arbitrary/function generator based on direct digital synthesizers (DDS).
The FG410 is a 1-channel generator, while the FG420 is a two-channel generator.
• Highest frequency: 30 MHz (sine wave), 15 MHz (square wave, pulse)
• Frequency accuracy: ±(3 ppm + 2 pHz), high resolution of 0.01 μHz. 10 MHz external frequency
reference can be used.
• Maximum output voltage: 20 Vp-p/open, 10 Vp-p/50 Ω
• Large number of standard parameter-variable waveforms: Sine wave, square wave (variable duty),
pulse (variable pulse width/duty, leading edge time, trailing edge time), ramp wave (variable
symmetry), CF controlled sine wave (variable crest factor), staircase sine wave (variable number
of steps), Gaussian pulse (variable s), Sin(x)/x (variable number of zero crossings), exponential
rise/fall (variable time constant), damped oscillation (variable oscillation frequency, damping time
constant), pulse surge (variable rising and duration times), trapezoid (variable rise, fall, and upper
base width), and so on.
• Large-capacity arbitrary waveform memory: 512 K words max., saving capacity: 128 waveforms/4
M words
• Phase and waveform remain continuous even when frequency is changed or during frequency
sweep.
• Square wave, pulse with variable duty and high resolution of 0.0001%
• Pulse with variable leading edge time and trailing edge time

duty, constant value/ linear interpolation, jump/ repeat/ hold/ branch
• Sequence function for easy test waveform creation and adjustment
Flexible waveform creation possible through combination with standard parameter-variable
waveforms
Frequency, phase, amplitude, etc., can be rapidly changed and swept
• Intuitive user interface through use of high-resolution QVGA TFT color LCD
• Two-channel ganged function with 2 phases, constant frequency difference, constant frequency
ratio, and differential output (only FG420)
• Floated from housing for each channel to reduce effect of ground loop

• The DDS (digital direct synthesizer) uses a 120 MHz clock to generate various types of oscillation
and waveforms. Modulation, sweep, burst, and sequence are also processed within the DDS.
• The digital waveforms generated by the DDS are controlled to the specified polarity (normal,
inversed) in the amplitude range (-FS/0, ±FS, 0/+FS), and following digital amplitude adjustment,
the signal is input into the digital to analog (D/A) converter.
• The waveform converted into an analog signal by the D/A is then smoothed by the lowpass filter
(LFP), and the amplitude is controlled in 10 dB steps by the programmable gain amplifier (PGA).
• The external addition signal and DC offset are added to the PGA output. When an output voltage
exceeding ±2V/open is required, output is done via the ×5 amplifier.
• The maximum output voltage of the product is either 20 Vp-p or 4 Vp-p depending on whether or
not the ×5 amplifier is used. Also depending on this, the external addition gain is either ×10 or ×2.
• After passing through the LPF, the external modulation signal undergoes A/D conversion and is
then input to the DDS.

GENERATOR
• The analog block is insulated from the system controller block located in the housing potential.
• In the FG420, the analog block comprises two channels, each individually isolated from the
housing potential.
Systemcontrollerblock
• This block performs control of the analog block, including the display, panel key processing,
remote control (GPIB, USB) processing, trigger input processing, frequency reference control,
DDS control, amplitude, and DC offset.
• A 20 MHz crystal oscillator is used as the basic oscillation of the DDS.
• The signal to synchronize multiple units is sent to REF OUT (frequency reference output), and the
inter-channel sync (FG420 only) is sent to the analog block of each channel.
Power supply block
• The AC/DC directly connected to the power supply input is in a constantly powered state.
• Control of each power supply circuit is done through power switch manipulation.
