As the title says, I need a suggestion on a 4ch portable scope for use ASAP (for working from home for the coming Chinese National Day from 10.1).
Therefore, I only consider established brands with good Chinese existence as if I was to get something like a CleverScope, the shipment won't make it.
Hard Requirements:
1. 100MHz+/4ch
2. Battery operation
Good to Have:
1. Channel-to-channel deskewing
2. Segmented memory
3. Isolation
4. Higher sample rate
Candidates:
1. Micsig STO1104C
Goods: cheap, large memory, true FPGA architecture, can also be used as a desktop scope
Bads: only 1gsps shared by 4 channels, bad LCD viewing angle (sort of IPS, but not true 178 degree IPS), no deskewing, no segmented memory
2. Fluke 190-204
Goods: quad isolated channels, higher sample rate (2.5Gsps/2ch, 1.25Gsps/4ch), ruggedized
Bads: expensive, only 10kpts memory, computer software is paid, no deskewing (not found in manual, presumed), no segmented memory (presumed)
3. PicoScope 2408B
Goods: powerful software, good memory depth, SDK available, in-the-middle price
Bads: no isolation, only 1gsps shared by 4 channels
Any other suggestions and any user's experience from either devices?
