The RIGOL MHO900-AFG100 Function/Arbitrary Waveform Generator Option expands a compatible RIGOL MHO900 Series oscilloscope with integrated dual-channel signal-generation capability. It is a licensed function upgrade rather than a separate benchtop waveform generator.
Once activated, the option allows engineers to generate controlled test signals while measuring circuit behaviour on the same oscilloscope platform. This combination is useful for electronics development, embedded-system testing, amplifier analysis, filter testing, control-loop evaluation, frequency-response measurements and educational laboratory work.
The AFG100 option provides a maximum sine-wave output frequency of 100 MHz, a 1 GSa/s sample rate and 16-bit vertical resolution. It supports standard, arbitrary, built-in and user-defined waveforms for a broad range of simulation and test requirements.
Supported Output Waveforms
The waveform generator supports the following basic waveforms:
- Sine
- Square
- Ramp
- DC
- White noise
- Arbitrary waveform
It also includes built-in waveforms such as:
- Sinc
- Exponential rise
- Exponential fall
- ECG1
- Gaussian
- Lorentz
- Haversine
User-defined waveforms are supported, allowing engineers to reproduce specialised test signals that are not available in the standard waveform library.
Waveform-Specific Frequency Ranges
The 100 MHz rating applies to sine-wave generation. The maximum output frequency varies according to the selected waveform:
- Sine: 2 mHz to 100 MHz
- Square: 2 mHz to 20 MHz
- Ramp: 2 mHz to 2 MHz
- Arbitrary waveform: 2 mHz to 20 MHz
- Built-in waveform: 2 mHz to 20 MHz
- White noise: greater than 100 MHz typical -3 dB bandwidth
This waveform-specific information should be considered when selecting the option for high-frequency testing.
Arbitrary Waveform Generation
The RIGOL MHO900-AFG100 supports arbitrary waveform generation with a waveform length of 16 kpts. Arbitrary waveform files can be imported in CSV format, making it possible to generate customised signals for simulation, fault reproduction and device-response testing.
Typical arbitrary waveform applications include:
- Sensor-output simulation
- Communication pulse testing
- Power-supply disturbance testing
- Control-signal simulation
- Reproduction of recorded signal patterns
- Custom waveform development
- Device stress and response testing
-
Frequency-Response and Bode Plot Testing
The AFG100 option supports the MHO900 Series Bode plot function. The oscilloscope uses the integrated waveform generator to excite the device under test while measuring its amplitude and phase response.
The supported Bode plot configuration includes:
- Start frequency from 10 Hz to 3 MHz
- Stop frequency from 100 Hz to 30 MHz
- 10 to 100 measurement points per decade
- Output amplitude from 20 mV to 10 V
-
This capability is useful for analysing:
- Amplifiers
- Active and passive filters
- Feedback networks
- Power-supply control loops
- Audio circuits
- Sensor-conditioning circuits
- Frequency-dependent components
- Educational electronics experiments
The Bode plot stop frequency is limited to 30 MHz even though the AFG sine-wave output can reach 100 MHz.
Modulation Capabilities
The option supports internal AM, FM and PM modulation. Available modulating waveforms include sine, square, triangle, upward ramp, downward ramp and noise. Supported carrier waveforms include sine, square and ramp.
The modulation functions are useful for:
- Communication-circuit testing
- Modulated-signal simulation
- Receiver and demodulator evaluation
- Educational experiments
- Frequency and phase response testing
- Fault-condition simulation
-
Suitable Applications
The RIGOL MHO900-AFG100 is suitable for:
- Electronic circuit design and debugging
- Embedded-system testing
- Frequency-response analysis
- Bode plot measurement
- Filter and amplifier testing
- Power-supply loop analysis
- Sensor and actuator simulation
- Communication circuit testing
- Automotive electronics development
- Research and development laboratories
- Production testing
- Educational engineering laboratories
- Device characterisation
- Custom waveform simulation

Installation and Activation
The MHO900-AFG100 is a licensed software function option for compatible MHO900 Series oscilloscopes. RIGOL’s ordering process requires the serial number of the target instrument so that the option can be activated for the correct oscilloscope.
The option can also be obtained as part of the MHO900-BND function and application bundle, which includes AFG100 and selected protocol-analysis options.
