GW Instek AFG-2225 25MHz Dual-Channel Arbitrary Function Generator Price in Bangladesh

N.B: This is a pre-order item.

The GW Instek AFG-2225 is a 25MHz true dual-channel arbitrary function generator designed for laboratory signal generation, electronics testing, circuit development, and waveform analysis. It provides two equivalent output channels, allowing users to generate and control two signals for applications such as differential signaling, phase-related experiments, amplifier testing, and other dual-signal applications.

The instrument provides a frequency range from 1μHz to 25MHz for sine and square waveforms, with 1μHz resolution across the full range. Standard waveform functions include sine, square, ramp, pulse, noise, and arbitrary waveforms.

For arbitrary waveform generation, the AFG-2225 provides a 120MSa/s sampling rate, 10-bit vertical resolution, and 4k-point waveform length. The unit also includes built-in arbitrary waveform editing capabilities and supports multiple methods for creating or modifying waveforms.

The two channels can operate independently or in correlated modes. Couple, tracking, and phase functions allow users to establish relationships between CH1 and CH2, making the instrument useful for experiments requiring synchronized or related signals.

What is an Arbitrary Function Generator?

An arbitrary function generator (AFG) is a laboratory instrument used to produce electrical waveforms with controlled frequency, amplitude, offset, and other parameters.

Unlike a basic signal generator that may provide only a few fixed waveforms, an arbitrary function generator can generate standard waveforms as well as user-defined waveforms.

The AFG-2225 combines standard signal generation with arbitrary waveform capability. Users can work with common signals such as sine, square, ramp, pulse, and noise, while also creating or editing arbitrary waveforms for specialized testing.

Technical Specifications

Specifications are based on GW Instek’s published AFG-2225 documentation.

Working Principle

The AFG-2225 uses digital signal-generation technology to create controlled electrical waveforms. The user selects a waveform and sets parameters such as frequency, amplitude, offset, phase, and duty cycle through the front-panel controls.

For standard signals, the instrument generates the selected waveform according to the programmed parameters. For arbitrary waveforms, digital waveform data is stored and processed at the specified sampling rate before being converted into the corresponding analog output signal.

The two output channels can operate independently or be correlated. The Couple function can establish relationships between frequency, amplitude, or DC offset. The Tracking function can coordinate CH1 and CH2, while phase control can be used when synchronized signals with a defined phase relationship are required.

The instrument also supports modulation, sweep, and burst functions, extending its usefulness beyond basic waveform generation.

Applications

The GW Instek AFG-2225 can be used for:

• Electronics laboratory experiments
• Analog circuit development
• Digital circuit testing
• Amplifier testing
• Filter response testing
• Audio-frequency experiments
• Sensor and signal-conditioning circuits
• Communication-system experiments
• Differential signal generation
• Phase-related signal experiments
• IQ-related laboratory experiments
• Arbitrary waveform testing
• Educational electronics laboratories
• Research and development
• Engineering test and measurement

Advantages

The AFG-2225 combines two full-function output channels in one instrument. Both channels provide equivalent characteristics, which is useful when two related signals need to be generated simultaneously.

Its broad frequency range, very fine frequency resolution, arbitrary waveform capability, modulation functions, sweep, burst, and frequency-counter functions provide flexibility for a wide range of laboratory experiments.

The USB Host and Device interfaces also support waveform editing and transfer workflows. GW Instek provides PC software for arbitrary waveform editing, and the instrument can work with compatible GDS-series digital storage oscilloscopes for waveform capture and reconstruction.

Limitations

The maximum sine and square-wave frequency is 25MHz, so applications requiring higher-frequency signal generation require a different instrument.

The arbitrary waveform memory is limited to 4k points, and the arbitrary waveform vertical resolution is 10-bit. These specifications should be considered when creating detailed custom waveforms.

Output amplitude also depends on load impedance and frequency. For example, the published maximum output specification is 10Vpp into 50Ω, while open-circuit output can reach 20Vpp under the specified conditions.

Installation / Usage Tips

Place the AFG-2225 on a stable laboratory surface with adequate ventilation. Connect the appropriate power cable and allow the instrument to operate according to the manufacturer’s recommended conditions.

Use suitable BNC cables and test leads for connecting the generator to the circuit under test. Verify the load impedance before setting the output amplitude because the displayed output level depends on the selected impedance configuration.

When working with two channels, check the selected coupling, tracking, and phase settings before enabling the outputs.

For arbitrary waveform experiments, verify the waveform shape and amplitude on an oscilloscope before applying the signal to a sensitive circuit. Use appropriate signal levels for the circuit under test.

Never connect the function generator directly to hazardous electrical sources or circuits outside the instrument and cable ratings.
