Technical Note - Centering Pulse Waveform
In a settling time measurement, rise/fall time calculation, and tests known as template fitting test, samplers are used to record waveforms. The test signal waveform in such applications is usually a clock signal with 50% duty ratio. You may want to shift this waveform in the unit test period window to a position so you can analyze and parameterize it. This technical note describes how to shift ("center") your waveform to any desired phase.

Mixed-signal Lecture Series: DSP-Based Testing Fundamentals 4 - Multi-tone Data Generation
Multi-tone is a popular stimulus signal in mixed signal tests. By using a multi-tone you can capture gain and phase information at multiple frequency points with a single measurement so that it is very effective in frequency response analyses. As discussed in the last newsletter, when a multi-tone is programmed and generated by a DAC, it has a gain shaping of SINC function. In this issue, let’s look at the waveform and think of the point of appropriate multi-tone signal generation. |
Question: "Why does my Total Harmonic Distortion result look poor?"
The THD result of an ADC is bad. I expected -58 dB THD of 1 MHz signal at 10 MHz bandwidth but it only has -41 dB. What is wrong? |
