SIGLENT Oscilloscopes, Analyzers & Signal Generators

SIGLENT Technologies Co., Ltd. (688112:SHH) is headquartered in Shenzhen, China, and is one of the few companies with R&D, manufacturing and sales across all four major categories of general-purpose electronic test instruments: digital oscilloscopes, vector network analyzers, spectrum analyzers and signal generators. It has subsidiaries in Oregon (USA), Augsburg (Germany), Tokyo (Japan) and Penang (Malaysia), and sells in over 80 countries and regions.

The range spans 12-bit high-resolution oscilloscopes from the SDS800X HD to the flagship SDS7000A with up to 8 GHz bandwidth, handheld scopes, benchtop and portable vector network analyzers, RF signal and spectrum analyzers up to 40 GHz, vector and microwave signal generators up to 67 GHz, arbitrary waveform generators, source/measure units, programmable DC power supplies, electronic loads and digital multimeters, plus software such as SigVSA vector signal analysis.

• High-resolution oscilloscopes: 12-bit SDS800X HD to SDS7000A series with up to 8 GHz bandwidth.
• Vector network analyzers: benchtop and portable VNAs for RF component and cable testing.
• Spectrum and signal analyzers: RF analysis up to 40 GHz with SigVSA vector signal software.
• Signal generators: vector, microwave (up to 67 GHz) and arbitrary waveform generators.
• Power and DC test: programmable DC power supplies, SMUs and electronic loads.
• Meters and accessories: digital multimeters, probes, compliance test options and fixtures.

A Vietnamese university can equip semiconductor and RF training labs with oscilloscopes, VNAs and spectrum analyzers. An IoT or telecom device maker can verify antennas and RF modules with portable VNAs. An EMS plant can build test stations around programmable supplies, loads and multimeters.

Labs and production lines can source oscilloscopes, VNAs, spectrum analyzers and generators from one vendor at accessible price points. 12-bit oscilloscopes give finer vertical resolution for power and sensor signals. A Penang subsidiary brings sales and support closer to Southeast Asian customers. Quality management is certified to ISO 9001:2015 and ISO 14001:2015, and trial units can be requested online.

Wider adoption of high-speed interfaces, RF and power electronics is increasing demand for high-resolution oscilloscopes and affordable RF instruments. Southeast Asia's electronics manufacturing, university labs and new semiconductor training programmes in Vietnam create volume demand for mid-range instruments with regional service, which Siglent targets through its Malaysian subsidiary.

Listed on the Shanghai Stock Exchange STAR Market (688112). Certified as a National High-tech Enterprise in China; 235 professional engineers, R&D spending about 22% of revenue and 373 patents. SIGLENT Malaysia was established in 2023 and its Penang subsidiary held a grand opening in 2025.
