Maybe yours did (you are relating direct experience I assume) but mine came with a device that looked nothing like the TW523 or its X-10 Pro version:
There was a toggle key where you could see the 1/0 complement bits or collapse that view into the actual X-10 binary format. Through the rather novel use of graphics on the line about the raw data they were able to then "group" bits that were valid into X-10 meaningful frames, indicating the cycle gap, single valid frames and entire valid commands. It read in all the bits its buffer could hold and then processed them. That's why I'm certain it would be useful in analyzing something like Bruce's very noisy power supply.
I used it to analyze two Palmpads "colliding" and the Lynx showed pretty much what the Monterey did. Lots of "almost" codes, some valid codes, some single frames and some valid commands that were on a house code that neither transceiver was set to. I have all the screenprints somewhere, but I have little more than a passing interest in this subject and certainly not enough to go dig up the LynX-10 data. I'm quite content to wait until Jeff has the noisy power supply in hand to see what's what.
This discussion reminds me of astronomy where there are hard and fast theories about what can and can't be until new evidence arrives, usually through the use of better tools like space-based telescopes, large array telescopes and image processing. The new and better evidence usually blows the old theories out of the water.
Scientists once again had to rewrite the textbooks when a NASA's Stardust mission traveled almost 3 billion miles during a seven-year round-trip from Earth to Comet Wild-2 and back again. The craft managed to snag some real comet material. It turns out the composition was far different from what earth-based observations had predicted and the legend of the comet as a dirty snowball was pretty much put to rest. That's why I'm more than willing to wait until Jeff actually has our "comet" in his hands and can observe its real-world behavior as opposed to theorizing how it should behave.
