--- 以下为原视频简介 ---
It's SIBAS 32 again! But this time, it's a simple 1000Hz carrier-based asynchronous modulation with a bunch of sync modes. The Class 332 and Class 333 aren't Desiro UK trains. Yes, built by Siemens Transportation Systems (now Siemens Mobility) but also CAF had a hand in its design as the manufacturer. It's known simply as a Suburban EMU.
Sorry, I can't distinguish between high pulse-counts and pulses that are simply wide here. Eventually, someone who can read the current waveform more diligently can identify them.
