It supports standard SCPI remote control commands, PC-based software, and compatibility with the latest mainstream multimeter command sets. Its embedded web server enables direct remote control and programming via a browser, fulfilling diverse communication and automation needs.
Web control
The SDM4065A high-speed 6½-digit multimeters strike a balance between speed, accuracy, and stability. Whether applied in automated control system testing, power engineering, electronics manufacturing and repair, telecommunications and networking, or scientific research and education, the SDM4065A series is dedicated to delivering a new measurement experience for engineers, enabling more precise and efficient testing.
SIGLENT Launches New 8 GHz Digital Oscilloscope！
July 10, 2025 — SIGLENT has unveiled the enhanced SDS7000A/AP models, building on the success of its SDS7000A high-resolution digital oscilloscope series. The new models now feature bandwidth up to 8 GHz, a high-resolution 12-bit ADC, maximum 20 GSa/s sampling rate per channel, and a maximum memory depth of 2 Gpts/ch. New capabilities include 2.5G/5G/10GBase-T Ethernet Electrical Compliance Testing, MIPI-DPHY protocol analysis, Real-Time Spectrum Analysis (RTSA), Digital Down-Conversion (DDC), and upgraded CAN XL decoding.
SIGLENT Expands RF Test Capabilities with the New SSG6082A-V Vector Signal Generator
With the ongoing advancement of wireless communication, the introduction of new mobile network standards, and the growing adoption of IoT and communication technologies, the demand for high-performance RF solutions continues to rise. Developers and engineers face increasingly stringent requirements, particularly in generating complex modulated signals that are essential for modern communication and IoT applications. To meet these growing demands, Siglent is expanding its portfolio with a new high-performance vector signal generator.
On March 12, 2025, SIGLENT introduced the SSG6082A-V Vector Signal Generator, a high-performance instrument with an output frequency range of 9 kHz to 8 GHz and a 500 MHz bandwidth IQ baseband source, significantly enhancing its portfolio of vector signal solutions. Concurrently, a firmware update for the PC Software SigIQPro will be released in synchronization with the SSG6082A-V, introducing expanded support for WiFi, 5G NR, LTE, and other mainstream communication protocols to streamline the generation of sophisticated signals.
Expanded Output Frequency and Power Range
With a maximum frequency of 8 GHz and a peak output level of 30 dBm for CW signals, the new generator serves as both a high-precision RF source and a carrier for modulated signals. Its wide frequency and power range meet the demanding testing requirements of many modern communication systems.
Wider Modulation Bandwidth and Superior Signal Quality
As data exchange rates between devices continue to rise, broadband communication technologies are becoming increasingly prevalent. The SSG6082A-V offers a modulation bandwidth of up to 1 GHz and excellent in-band response, thanks to precise in-factory calibration, making it suitable for a wide range of communication test scenarios.
The SSG6000A-V series features ultra-low phase noise, reaching -132 dBc/Hz at a 10 kHz offset for a 1 GHz signal. Higher spectral purity reduces test errors, enhancing the accuracy and reliability of measurement results. In wireless communication, low phase noise signals help minimize bit error rates (BER), improving communication stability and reliability.
Phase noise at different carrier frequencies
For modulated signals, the SSG6082A-V delivers an excellent adjacent channel power ratio (ACPR), ensuring high-quality signal generation while maintaining the target output power. This minimizes neighboring channel interference during multi-channel testing, enabling more accurate simulation of real-world communication environments.
5G NR Test Mode TM1.1 100M bandwidth ACPR
More Accurate Transmitter Simulation
The SSG6082A-V supports automatic amplitude, frequency, and phase compensation based on the S2P file of the test system. This compensation minimizes phase fluctuations and phase noise while flattening the signal amplitude across the entire frequency range, ensuring consistent signal levels at different frequencies. With enhanced system compatibility, the SSG6082A-V accommodates a broader range of applications, delivering precise and efficient test system performance.
