15.11.2 SPI and SSPI (Option R&S RTB-K1)
The Serial Peripheral Interface (SPI) is used for communication with slow peripheral
devices, in particular, for transmission of data streams.
SSPI is a Simplified SPI configuration without chip select line.
A 4-channel instrument is required for full support of the SPI and SSPI protocols.
The SPI/SSPI protocol requires two bus lines (bus 1 and 2 or bus 3 and 4), so the
number of buses (suffix <b>) is reduced. Bus 2 and/or bus 4 is not available.
