Jitter analyzer. I say unlikely, given that jitter analysis is usually found in high-bandwidth oscilloscopes. I think we've established that's not the case here. Moving on.
Power analyzer. That's possible because you don't need high bandwidth for testing switching power supply circuits. Having frequency plots is essential in power analysis. This could be a response to Yokogawa's recent announcement of the PX8000.
Protocol analyzer. Many oscilloscopes have software that lets them decode protocols such as SPI, I2C, or RS-232. Thus protocol analyzer is a possibility.
Frequency counter. This feature could be considered part of a multimeter function. B&K precision has a frequency counter in an analog oscilloscope, but Tektronx has been out of the analog oscilloscope market for a long time.
Power supply. An oscilloscope that's also a power supply? That would be a first. Interesting idea, though how much power would you want your oscilloscope to provide? Still, I think it's possible.
There are my 10 choices for a 6-in-1 oscilloscope. What's your guess?
