Vector Network Analyzers of Rohde&Schwarz family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT...

The X-500 & X-55 SSDs use an internal DRAM, but only management data is cached in the DRAM, no user data (as done in other SSDs). User data is always processed through the small internal controller cache directly into the flash chips.
Together with the user data, also the page mapping information is saved into...

PCI was originally designed as an interconnect for personal computers; because of the nature of PCs at that time, the protocol architects did not anticipate the need for multiprocessors. Therefore, they designed the system assuming that the host processor would enumerate the entire memory space. Obviously, if another processor...
