The MFG-2000 Series is a versatile multi-channel function generator designed for advanced testing, measurement, and signal simulation applications. Depending on the model, the instrument provides up to five simultaneous output channels, integrating several signal generation functions within a single platform.
The available channels include CH1 and CH2 high-performance dual-channel arbitrary function generators with frequencies up to 200 MHz for each channel. The series also features an RF signal generator capable of producing sine waves up to 320 MHz with multiple RF modulation options, a pulse generator with frequencies up to 25 MHz, and a power amplifier optimized for audio frequency applications.
These five functional channels are distributed across 11 different models, ranging from basic single-channel arbitrary function generators with pulse generator capabilities to advanced five-channel configurations. This flexible architecture allows the MFG-2000 series to meet the needs of a wide range of educational, laboratory, and industrial applications.
Arbitrary Function Generator Performance
The AFG channels of the MFG-2000 series can generate standard waveforms such as sine, square, and triangle waves, along with user-defined arbitrary waveforms. The instruments feature true point-by-point arbitrary waveform output with a sampling rate of 200 MSa/s, a waveform repetition rate of 100 MHz, 14-bit resolution, and a memory depth of 16k points.
The MFG-2220HM model provides enhanced performance with a sampling rate of up to 250 MSa/s and a repetition rate of 125 MHz.
Selected models support various modulation types including AM, FM, PM, FSK, and PWM. Additional functions available on certain models include sweep, burst, trigger operation, a built-in 150 MHz frequency counter, and a 25 MHz pulse generator. Dual-channel synchronized models also provide advanced correlated functions such as synchronization, delay, sum, and channel coupling.
RF Signal Generator and Pulse Generator
The integrated RF signal generator functions as a complete AFG signal source, including arbitrary waveform generation. It supports multiple modulation modes, frequency sweep functions, and digital modulation schemes such as ASK and PSK. The sine wave output frequency can reach up to 320 MHz.
All models include a full-featured pulse generator with frequencies up to 25 MHz. Pulse width, rise time, and fall time are fully adjustable, allowing the generator to be used for triggering and synchronization applications.
Power Amplifier for Audio Applications
An independent input/output power amplifier is available on selected models, delivering up to 20 W of output power with 20 dB gain. The amplifier offers a bandwidth of 5 Hz to 100 kHz and total distortion below 0.1%, making it suitable for audio testing and speaker evaluation.
Advanced Isolation Design
The MFG-2000 series (except the MFG-2220HM model) features earth-ground isolation between the input/output terminals and the instrument chassis, a design typically found only in high-end signal sources.
The output channels can withstand an isolation voltage of up to ±42 Vpk (DC + AC peak) relative to earth ground, making them ideal for floating circuit testing. This design allows multiple units to operate simultaneously without grounding reference issues.
Experiments such as full-wave rectification or voltage doubling can be performed safely without additional isolation devices. An external power supply can also be used to increase the DC bias voltage up to ±42 Vpk, which is particularly useful for automotive and educational applications requiring higher bias levels.
Waveform Editing and Reconstruction Software
The MFG-2000 series supports AWES (Arbitrary Waveform Editing Software), allowing users to easily create and edit custom waveforms. The DWR (Direct Waveform Reconstruction) function enables waveform capture from compatible GDS series digital oscilloscopes and direct reconstruction on the arbitrary waveform generator.
In addition, the system includes 102 built-in waveforms that can be used directly or modified by the user. Individual waveform segments can also be edited and output independently.
Applications
Thanks to its multi-functional design, the MFG-2000 series supports a wide variety of applications across multiple industries. Typical applications include:
- Dual-channel waveform simulation for industrial testing
- Low-frequency vibration simulation
- Automotive sensor testing
- Medical electronics signal simulation (except MFG-2220HM)
- AM/FM broadcast signal generation
- PWM motor and fan control signal generation
- Pulse synchronization and noise signal testing
- Audio circuit and speaker testing
The MFG-2000 series is therefore an ideal solution for scientific research, education, research and development, production testing, and quality control environments.

to increase D.C. bias voltage to ±42Vpk (DC+ AC peak value).
The output channels, as well as the synchronization and modulation input/output connectors, are electrically isolated from the instrument chassis. This design allows the connectors to withstand a maximum isolation voltage of up to ±42 Vpk (DC + AC peak value) relative to earth ground, making the system ideal for floating circuit testing.
Multiple instruments can therefore operate simultaneously without grounding reference issues. The built-in DC bias voltage of the MFG-2000 series can be applied to various waveforms and provides ±5 V under a 50 Ω load.
An external power supply can also be used to increase the DC bias voltage up to ±42 Vpk (DC + AC peak value) for applications requiring higher bias voltages.

RF Signal Generator
The RF signal generator operates as a full-featured AFG signal source. Similar to channels CH1 and CH2, it can generate a variety of waveforms including sine, square, ramp, pulse, and noise.
The sine wave frequency can reach up to 160 MHz or 320 MHz depending on the model. The true point-by-point arbitrary waveform generation function supports a 200 MSa/s sample rate, 100 MHz waveform repetition rate, 14-bit resolution, and 16k point memory depth.
The RF generator also supports frequency sweep and multiple modulation types including AM, FM, PM, FSK, PWM, PSK, and ASK.
It can be used as a high-frequency arbitrary waveform generator, a simulator for analog or digital broadcast signals, or as a carrier signal source for local oscillators.

amplifier of the MFG-2000 series to realize various physics experiments.
A 20 W power amplifier with 20 dB gain is available, providing a bandwidth of 5 Hz to 100 kHz and distortion lower than 0.1%.
This low-frequency power amplifier can be used as an audio amplifier or as a driver amplifier for piezoelectric components (in combination with an impedance transformer for a 20 W output).
It also enables testing of power component characteristics and magnetization characteristics (B-H curves) of magnetic materials such as ferrite and amorphous materials.

Burst Function
The series supports N-cycle burst mode or gated triggering.
Parameters such as phase angle, duration time, frequency, and waveform can be adjusted to meet the requirements of non-continuous signal output applications.
Correlated Output Functions for Dual Channels
Channels CH1 and CH2 on the MFG-2220HM, MFG-2230M, MFG-2260M, MFG-2260MFA, and MFG-2260MRA models can be used independently or with correlated functions.
Four correlated functions are available: sum, coupling, tracking, and phase control.
- Coupling: allows users to freely define frequency and amplitude ratios and offsets between both channels.
- Tracking: generates differential signals with a 180° phase offset.
- Phase: allows precise phase adjustment between signals such as sine, cosine, or square waves.
- Sum: combines two signals into a single output, useful for applications such as adding noise to a sine wave during speaker distortion testing.
