Well, they probably put some DRAM in which is not full speed but limited to the MSa/s range or whatever.
right, you can even find something about in the user manual, see pictures.
Translated :
single channel - short memory 6kpts, long memory 16Mpts
dual channel - short memory 6kpts, long memory 8Mpts each
so definitely there is more memory inside. From the pure size to price ration must be SDRAM/DDR
therefore possible that the long memoryis even 1GSs running.
more "interessting" is this :
Waveforms/sec: 150,000 This is a lot for FPGA based device, when this is truth (combined with the memory depth) the UNI-T
managed to create something nice - when the firmware has been modified from what it was on older models.
I would be really happy if someone could make pictures of what inside
