[QUOTE="Scott Helmke, post: 15783, member: 96"] Re: Damn you Bennett! I've noticed a couple things using SMAART with a USBPre. One is that the USBPre (the older version) outputs tend to act a little funny when loaded down. Rational recommends using a Y-cable for the reference signal, so that if the output gets loaded funny and changes response it won't matter much to the measurement. The other is that SMAART doesn't have very fine delay resolution compared to high frequency phase. So when I measure a digital device the phase trace often goes well away from 0 degrees at high frequencies, because there isn't a delay compensation setting that exactly matches the test device latency.
