IM FG410-01EN
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
• Various oscillation modes
• Continuous oscillation
• Modulation: FM, FSK, PM, PSK, AM, DC offset modulation, PWM
• Sweep: Frequency, phase, amplitude, DC offset, duty
• Burst oscillation: Auto burst, trigger burst, gate oscillation, triggered gate oscillation
• Sequence oscillation: Variable waveform/ frequency/ phase/ amplitude/ DC offset/ square wave
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
• Multiple-phase oscillator can be configured by synchronizing multiple units
• USB and GPIB interfaces provided
• Thin and lightweight: Height of approx. 9 cm, weight of approx. 2.1 kg
