App Note FFT
Fast Fourier Transforms with Rigol Oscilloscopes
FFT (Fast Fourier Transform) is a process which converts a time‐domain
signal into its frequency domain equivalent. Common applications for usage
of FFT waveforms are:
- Measuring harmonic content and distortion in systems
- Characterizing noise in DC power supplies
- Analyzing vibration

Benefit of Large Memory Depth in modern Scopes
When many people are looking for a new scope, Memory Depth is very often only the third or fourth point on their list of key parameters. The initial specifications that everyone is thinking about are bandwidth, sample, and Acquisition Rate. But a fundamental spec that can provide great benefit is memory depth.

Although the size and weight of the DSA800's make it attractive for use in
locations where there is no power, it suffers from the lack of an internal
battery. A Google search uncovers a raft of battery backed up power supplies
but the recommendation is that the DSA800's run from a supply that has a

App. Note DSA815 - EMI / EMC - EMC Precompliance
I wanted to write to let you all know that we are meeting with great success with EMI and EMC test labs here in North America.
Here is some back story. EMI/EMC Compliance labs use software packages that integrate the hardware (Spec Ans, Sources, Amplifiers, etc..), data analysis, and report generation tools. Each of these requires a software driver to communicate to the hardware to configure and collect data.
I am happy to report that we have been in communication with some of the development teams for two of the largest EMI companies.. and both ETS/Lundgren and Teseq are going to be building drivers for the DSA-815!
This will allow seamless integration of the Rigol DSA-815 into any test labs that use ETS/Lundgren TILE! or Teseq Compliance software in their labs.
We are also investigating having the DSA-815 tested against CISPR-16 specifications. This will allow us to know "how close" the DSA-815 is to "full compliance". This will highlight our strengths and point to the areas that will need further development for a full compliance EMI receiver. It will also allow us to help customers understand the differences between a precompliance instrument and a full compliance instrument.
Very exciting times here at Rigol!
