M300 System Measurement Primer

Introduction to data acquisition with Rigol’s M300 The M300 Data Acquisition System is designed for automated multichannel measurement and switch applications. This includes environmental measurements like temperature for burn in tests as well as voltage, frequency, or resistance measurements from a wide variety of sensors used from research to production test. These applications are actually v...

SiFi Technology in Arb Wave Creation

Introduction to Waveform Generator Technology Traditional function and arbitrary waveform generators have for many years been built on one common technology – DDS or Direct Digital Synthesis. DDS allows an instrument to create waveforms by tracking the phase of a reference clock and outputting the closest sample to the desired signal at each output sample time. DDS has enabled quality performan...

SiFi 2 Technology and 16 Bit Resolution App Note

Unique waveform reproduction technology RIGOL’s newest arbitrary waveform generators, the DG800 and DG900 Series, combine high resolution output and advanced filtering techniques in point-to-point waveform generation expanding the value of arbitrary waveform generators in test platforms. The DG800 and DG900 (shown in Figure 1) each have our new 16 bit output capability which improves the accura...

Advanced Embedded Debug with Jitter and Real-Time Eye Analysis

Introduction Debugging embedded communications is one of the most common tasks for electronic design engineers. Efficient Analysis of serial communications requires more than simple triggering and decoding but historically there has been a significant cost difference between the oscilloscopes with mixed signal, serial triggering, and serial decode capabilities and the high performance instruments...

Bode Plot Analysis of switching Power Supplies

Overview A Bode plot is a graph that maps the frequency response of the system. It was first introduced by Hendrik Wade Bode in 1940. The Bode plot consists of the Bode magnitude plot and the Bode phase plot. Both the amplitude and phase graphs are plotted against the frequency. The horizontal axis is lgω (logarithmic scale to the base of 10), and the logarithmic scale is used. The vertical a...

Debug & Analysis of IoT Power Requirements

Power and Function The relationship between power and function in an Internet of Things (IoT) project is perhaps the most fundamental trade-off a design team needs to address; therefore, it must be made with definitive, testable goals from the customer’s perspective. Expert product development always begins with the an IoT development where the final product is a wrapper around the ‘big idea�...

Utilising Deep Memory with Rigol DS1000 Oscilloscope

Long Memory Storage with Rigol Oscilloscopes Some Digital scopes offer the capability of capturing waveforms in Long Memory mode. Utilising the long memory, Rigol scopes can capture complex signals in great detail over extended time periods. This allows an observer to examine high frequency effects within the captured waveform. How to use Long Memory Mode on the DS1000D/E Series scopes? Ent...

Debug and Analysis Considerations for Optimising Signal Integrity in your Internet of Things Design

Introduction As the Internet of Things continues to expand to include applications including home automation, fitness, video, and tracking as well as traditional embedded electronics use cases the needs for testing and optimising these designs become clearer. Even as IoT expands, the test requirements have begun to crystallise into a set of capabilities that can assist a design team in achieving ...

Meeting Embedded Design Challenges with Mixed Signal Oscilloscopes

Introduction Embedded design and especially design work utilising low speed serial signalling is one of the fastest growing areas of digital electronics design. The need to communicate between modules, FPGAs, and processors within a wide array of consumer and industrial electronics is increasing at an astounding rate. Customised communication protocol and bus usage is critical to design efficienc...
