Super Phosphor Oscilloscopes
SDS2000X-E Series
The SDS2000X-E series employs a new generation of SPO technology. With its excellent signal fidelity, background noise is lower than similar products in the industry. It has a minimum vertical input range of 500 uV/div, an innovative digital trigger system with high sensitivity and low jitter, and a waveform capture rate of 400,000 frames/sec (sequence mode). It also employs a 256-level intensity grading display function and a color temperature display mode not found in other models in this class. Siglent’s newest oscilloscope offering supports multiple powerful triggering modes including serial bus triggering and decoding. History waveform recording and sequential triggering allow for extended waveform records to be captured, stored, and analyzed. Also included is the deep memory FFT. This math function uses upto 1 M samples for the FFT calculation, providing the SDS2000X-E with very high frequency resolution. The hardware co-processor executes true fast measurement and math to all of 28M sample points so that there is minimal distortion on analysis. It also supports searching and navigating, on-screen Bode plot, 16 channel digital /MSO (optional), an external USB powered 25 MHz AWG function generator module (option), a USB WIFI adapter for wireless control and monitoring (option), and an embedded application that allows remote control via web browser. The features and high-performance of the SDS2000X-E oscilloscopes cannot be matched else anywhere at this price.

VLF Electromagnetics
VLF surveying relies on radio signals that are broadcast from navigation stations around the world. The principle is that these signals are deflected in certain ways when they pass through conductive ore or water-filled vertical-to-sub-vertial fractures in the earth. By monitoring these deflections, the position and, potentially, size of the target can be determined.

20 GHz Signal Source
VCO Series
The SC5510A and SC5511A are VCO-based, synthesized signal sources with very low phase noise and an amplitude control of 0.01 dB throughout its -30 dBm to +15 dBm output power range. By utilizing a unique multiple phase-locked loop architecture, phase spurs are kept below -70 dBc across the entire tuning range, even at 1 Hz step resolution. Download the data sheet to see how the impressive features and specifications of these modules make them stand out when compared to other small modular synthesizers. These 20 GHz signal sources include an additional, independent RF2 channel with a tunable frequency range from 100 MHz to 3 GHz and a tuning resolution of 25 MHz. The extra channel makes the modules suitable for either single-stage RF conversion systems or dual-stage image suppression up/down converter systems. Both modules make great general-purpose laboratory signal sources where demanding low phase noise and signal purity are required. They are both ideal choices as an integrated clock source for fast DAC and ADC applications, especially those that require variable sampling rates. Full implementation instructions, GUI, driver software, and example code are provided with each module.
