Saelig Introduces Siglent SDS7000A 4 Channel 12-Bit 4GHz MSO Oscilloscope Series

Siglent’s first high-bandwidth, high-resolution oscilloscope SDS7000A series offers bandwidths up to 4 GHz, 12-bit resolution, and a sampling rate of 20 GSa/s, together with a matching high-bandwidth active differential probe SAP5000D.

Fairport, NY. Saelig Company, Inc. has announced the Siglent SDS7000A series of high-bandwidth, high-resolution oscilloscopes with advanced features such as 20GSa/s sampling, 12-bit vertical resolution, and 500 Mpts per channel memory. Using 12bit ADCs to limit quantization errors aids greatly in observing small signal details. The noise floor on the 7000A series is as low as 220μVrms at 4 GHz bandwidth and the waveform capture rate reaches 1 million wfm/s, ideal for capturing abnormal events. The SDS7000A scopes have a 15.6-inch high-definition touch screen for analyzing all signal channels simultaneously and improving operational efficiency. 16 digital channels are also available for high performance mixed signal analysis.

The SDS7000A series supports multiple automatic parameter measurements, such as jitter and eye characterization, with easy setup to speed debugging tasks and simplify engineering design testing. Siglent also provides embedded compliance test solutions to evaluate systems versus communication standards including USB 2.0, 100base-TX, 1000base-T, 100base-T1 and 1000base-T1. Users can configure the test items, allowing software to control the oscilloscope to automatically complete the defined test, and automatically provide signal test results (Pass/Fail) after comparison with reference standards. This helps to speed up, identify, and resolve critical signal and transmission issues. The trigger system supports multiple powerful triggering modes including serial bus triggering. Tools such as History waveform recording, Search and Navigate functions, Signal Scan, Mask Test, Bode Plot, Power Analysis, Eye/Jitter Analysis and Compliance Test allow for extended waveform records to be captured, stored, and analyzed.

The oscilloscope is supported by the SAP5000D 5GHz active differential probe for detailed signal analysis. Its high input resistance and low input capacitance ensures that the load introduced by the measurement system is minimized. The probes do not need an additional external power supply and are automatically recognized by the oscilloscope via an intelligent SAPBus interface, making them also suitable for oscilloscopes in the SDS5000X, SDS6000A and SDS7000A series.

The Siglent SDS7000A series of high-bandwidth, high-resolution oscilloscopes consists of two models: SDS7404A (4GHZ) and SDS7304A (3GHz). They are available now from Saelig Company, Inc. For detailed specifications, free technical assistance, or more information,  please contact Saelig at 1-888-7SAELIG, via email:, or visit

What are the Differences Between an Integrated ADC and a Standalone ADC?
Sponsored by Mouser Electronics and Microchip
Many designs today require some form of analog to digital conversion but how you implement an ADC into your design can make a big difference when it comes to accuracy and precision. In this episode of Chalk Talk, Iman Chalabi from Microchip and Amelia Dalton investigate the benefits of both integrated ADC solutions and standalone ADCs. They discuss the roles that internal switching noise, process technology, and design complexity play when choosing the right ADC solution for your next design.
