Siglent Introduces High-Speed 4GHz 12bit 20Gsample/s Scope

New Flagship Oscilloscope from Siglent

Siglent has introduced its latest addition to the oscilloscope range, the SDS7404A. This new flagship model boasts impressive features including a 4GHz bandwidth, 12bit resolution, and a sampling rate of 20Gsample/s.

The SDS7404A is equipped with four analogue channels and 16 digital channels. It offers a remarkably low noise floor of only 220μVrms at 4GHz bandwidth. At a sampling rate of 20Gsample/s, the effective number of bits (ENOB) is typically 7.3bit.

It is important to note that the maximum sampling rate of 20Gsample/s is only available when using two of the four channels. If all four channels are in use, the sampling rate is reduced to 10Gsample/s for each channel.

The full bandwidth of the oscilloscope can be achieved by using coaxial probes and setting the inputs to 50Ω. The SDS7404A comes with four general-purpose probes that offer 500MHz per channel. For users requiring even more bandwidth, Siglent has developed an optional 5GHz active differential probe called the SAP5000D.

The SAP5000D features an 80ps rise time, 400fF differential input capacitance, and a 10:1 attenuation ratio. It does not require an external power supply and is automatically recognized by the oscilloscope.

The SDS7404A has a capture rate of 1Mwaveform/s and an acquisition depth of 500Mpoints per channel, which can be upgraded to 1Gpt/ch. The oscilloscope is powered by an x86 processor, which significantly improves the system's response speed, measurement accuracy, operation, and analysis speed.

The instrument is equipped with a 15.6-inch multi-touch screen that offers a 256-level intensity display grading and a color temperature mode. In addition to touch and manual controls, a mouse can be connected, and the oscilloscope can be controlled remotely via its LAN port.

Siglent's SDS7404A features a versatile trigger system that supports multiple modes, including serial bus triggering. The oscilloscope also offers various tools for waveform recording, search, navigation, signal scanning, mask testing, Bode plot analysis, power analysis, eye analysis, jitter analysis, and compliance testing.

Embedded automatic compliance tests include USB 2.0, 100base-TX, 1000base-T, 100base-T1, and 1000base-T1. Additionally, an optional built-in 50MHz arbitrary waveform generator is available, capable of outputting six basic waveforms and multiple arbitrary waveforms with amplitudes up to ±3V.

For enhanced accuracy, the SDS7404A can be equipped with an OCXO (ovened timebase oscillator) option, offering ±100ppb initial accuracy at 25°C, ±1ppb drift over 0-50°C, and ±50ppb over the first year of use.

Siglent also offers a 3GHz bandwidth version of the oscilloscope, the SDS7304A, which features a slightly improved noise floor of 180μV and an ENOB of 7.5bit.
