The Siglent SDG2042X function generator is an advanced tool designed for electronic applications that require precise and reliable signals. With two independent channels and 40 MHz bandwidth, this generator lets you create a wide variety of waveforms for testing and development in the lab.
This model incorporates TrueArb technology, which generates arbitrary waveforms point by point, eliminating jitter and the distortions typical of other DDS methods. This ensures a stable signal with jitter below 150 ps, ideal for sensitive measurements and experiments.
It also features innovative EasyPulse, which allows square or pulse signals to be generated with rise and fall times adjustable with high precision and low jitter, overcoming the traditional limitations of DDS generators.
The SDG2042X supports multiple digital and analogue modulation modes, such as AM, FM, PM, FSK, ASK and DSB-AM, both internal and external, making it easier to simulate different signal scenarios.
Its standout features include:
- Burst generation for sine, square, ramp and arbitrary waves with phase and duration control.
- Linear and logarithmic sweep modes with upward or downward direction, useful for frequency response analysis.
- Integrated frequency counter with a range of 0.1 Hz to 200 MHz, independent of the output channels.
Key specifications:
- Maximum bandwidth: 40 MHz
- Frequency resolution: 1 µHz
- Sampling rate: 300 MSa/s, with interpolation up to 1.2 GSa/s
- Maximum output voltage: 20 Vpp
- Number of channels: 2
This generator is suitable for a range of electronics applications, from circuit development and testing to technical education and research. Its intuitive touchscreen interface makes signal setup and control easy.

Customer Questions & Answers
What benefits does TrueArb technology offer compared with traditional DDS generators for arbitrary signals?
Siglent's TrueArb technology removes typical DDS issues such as jitter and distortion by generating waveforms point by point from memory. This results in very low jitter (<150 ps) and faithful reproduction of arbitrary signals even with complex or very fast waveforms, which is not always possible with conventional DDS.
What are the dimensions, weight and exact box contents of the unit?
The SDG2042X generator measures 261 mm × 112 mm × 331 mm and weighs approximately 3.35 kg. Standard contents include: main unit, 2 BNC cables, 1 power cable, printed manual and support software CD. Minor accessory variations may apply depending on the region.
What electrical requirements and compatibility does it have for operation and integration in a laboratory?
The unit operates from a universal AC supply input of 100 V to 240 V, 45–440 Hz, with maximum power consumption of 40 W. Outputs are standard BNC connectors, compatible with most laboratory instruments. It is suitable for environments with stable mains voltage and effective grounding.
What are the maintenance recommendations and warranty and spare-part options for the SDG2042X?
It requires periodic external cleaning and should be kept away from dust and moisture. Internal fans operate automatically, and the ventilation grilles should be kept clear. The standard warranty is usually 3 years, parts and labour, although this may vary by region. Siglent offers spare parts and authorised technical service; check official distributors for after-sales support.
