Dave investigates two very serious issues with jitter on the Rigol DS1000Z series oscilloscopes, including the DS1104Z and new DS1054Z
Some sort of modulated sampling/trigger jitter problem at 5 microsecond intervals (the “5us jitter problem”). And severe jitter with the AC coupled trigger mode, a problem which is also present on the DS2000 series scopes as well.

Today, we’ll be discussing Rigol’s MSO2302A Mixed Signal Oscilloscope from the MSO2000A series. Starting at $1,239, this oscilloscope features 300 MHz bandwidth, with 2 giga-samples per second, a memory depth of 14 megapoints (Mpts), with an option up to 56 megapoints. The large 8 inch high resolution screen typical to Rigol scopes allows for easy review of your data. 2 channel input and has an ethernet connection for networking and USB ports to interface with computers, save waveforms to USB storage devices, or print directly to printers.

Dave shows you how to reverse engineer a PCB to get the schematic. In this case the new Rigol DS1054Z oscilloscope.
How does the discrete transistor analog front end and the software bandwidth limiting work?
How do you decode SMD transistor codes?
How does it compare to the old Rigol DS1052E?
Dave also discusses the low voltage ohms function of a mulitmeter, how it’s useful, and how to test your multimeter to see if it will have any issues with in-circuit testing.

Saelig Company Inc. (www.saelig.com) has announced the availability of MSO functionality to their range of Rigol DS2000A and DS1000Z scopes. The mixed-signal extension provides digital signal debug capabilities to the user, allowing simultaneous viewing of analog and digital signals for comprehensive signal analysis. Both models leverage Rigol’s Ultravision technology from the DS6000 series, offering superior performance and functionality in this class.
Designed to reduce test time in research, development and failure analysis applications, the MSO2000A and MSO1000Z series digital oscilloscopes facilitate detecting signal and device characteristics with comprehensive trigger functions, hardware-based real time waveform records, replay, search and analysis functions. The multi-lingual user interface allows easy configuration of the oscilloscopes in the local language.

In this episode Shahriar explores the world of filters! Starting from a simple lumped RC filter, he briefly covers the theory before moving onto measurement techniques. The bandwidth of the filter is verified experimentally in the time domain. A more complex RLC band-stop filter is also demonstrated with a tune-able inductor which is measured using an RLC meter. Using a Rigol spectrum analyzer with built in tracking generator and an active probe, the frequency response of the filter is measured. Several other packaged filters are also demonstrated and a microwave band-pass filter is disassembled to reveal its internal construction.

High-performance RF signal source family offers AM/FM/Phase modulation with I/Q modulation option
Fairport NY: Saelig Company Inc. (www.saelig.com) has introduced a high-performance RF signal source family, the DSG3000 3GHz/6GHz series, offering standard AM/FM/Phase modulation, as well as options for I/Q modulation and I/Q baseband output. The DSG3000 Series generates waveforms with high signal purity, typical phase noise of less than 110dBc/Hz@20kHz, and a wide output range of -130dBm to +13dBm. The DSG3000 RF signal generator has standard pulse modulation with an on/off ratio of up to 80dB, with an optional pulse train generator also available. The DSG3000 series has a typical amplitude accuracy of better than 0.5dB, and the standard 0.5ppm internal clock can be upgraded to an optional 5ppb high stability oven-controlled clock.
The DSG3000 series RF signal generators support internal and external modulation capabilities and operate with USB, LAN, LXI-C, and GPIB remote control interfaces. They also feature a wear-free electronic attenuator design and an automatic flatness calibration function via external automated power meter control over USB. This can be used as an automatic flatness calibration test system functionality for cables, attenuators, amplifiers, etc. The DSG3000ʼs standard 2U height is designed to save space when used with the optional rack mount kit.
Offering remarkable value for the money, the DSG3000 Series RF source is ideal for applications in wireless communication, radar test, audio/video broadcasting, as well as for general purpose, educational, and consumer electronics needs.
DSG3000 Signal Generators are made by RIGOL Technologies, a rapidly growing test and measurement company and the worldʼs second largest oscilloscope manufacturer by volume. RIGOL delivers high quality, high performance and value-priced test equipment for engineers, technicians and students worldwide. Offered with a remarkable 3-year warranty, the DSG3000 series is available now from Saelig Company, Inc. 1-888-772-3544 firstname.lastname@example.org

This is a review / buyer’s guide / tutorial on the Rigol DS2000 / DS2072A. As this is my first oscilloscope review I’ve gone into a little more detail for those new to oscilloscopes. I’m trying to use a standard set tests for this review which will carry through to future reviews so comparisons can be made between oscilloscopes.
I will do a side by side review of the Rigol DS2000 vs the Agilent DSOX2000 in the future. In this review I do make comparisons and references to the Agilent 2000 X series.

In this episode Shahriar extensively reviews the Rigol DSA1030A-TG3 Spectrum Analyzer. A wide variety of experiments are performed using the Rigol spectrum analyzer to serve both as a tutorial to use the instrument and to demonstrate its capabilities. Some measurement results are also performed using other calibrated instruments to verify the accuracy of the spectrum analyzer. The Rigol DSA1030A-TG3 can be purchased directly from Rigol Inc.
