Thank you for all the replies.
A solution with a PC is out, as I will have to take the unit with me and need everything in one box.
The RTB202 has only 128k of datapoints for the FFT against 1M in the Rigol. Does this make a differnece (esp. at the low frequencies)?

Let me just say this and won't bother you any more..
Picoscope 4224 IEPE has built in IEPE interface, it's 12 bit, it has 32MPoint mem. Picoscope software has advanced arbitrary math, custom probes. Ability to save complete measurements, setups etc. is very useful and implemented much better on a PC. That is pretty much instrument made for vibration analysis.
And as I said, you can capture whole day long, save it all and take it home to analyse the crap out of it, then create documentation or send data to colleagues, they can open it on a PC without Pico connected and analyse away....
As for portability, if I travel, I have to take my laptop with me anyway. This is one handheld box, that you connect with one USB cable and you are measuring. You get your power from PC, so you can run from battery. I got a small 14" laptop with I7 and high capacity battery, and just throw a Pico in the laptop bag, next to the power supply.
That complete bag is not heavier or bigger than Rigol 1000Z in carrying bag.
If you throw in a Signal Hound SA in other pocket you can carry whole lab with you in single bag.
If you have your reason for insisting on standalone instrument, it's your choice, no arguing that.
But for that particular use, that is most portable, best specced instrument for that price, period.
Sorry for being insistent, I just wanted to lay out all the facts, and from previous posts I wasn't sure you have all the info.
Best regards,
