An oscilloscope with isolated channels is also the best solution for unknown environment. it is a useful tool for especially power supply of electronic equipment, differentiated grounds on the boards, sensors and associated electronics not referenced to ground, couplers, transformers, communication systems, electronic systems not powered by the mains or not referenced to ground.

In Equivalent-Time Sampling mode, you can sampling up to 4.5GS/s for repetitive signals.

Internal 8MB USB disk could be used to store waveform and upgrade firmware.
