Pattern Generation
Sets the type of pattern the R&S CMW generates and sends to the MS.
●
Random : Sends a random pattern to the MS and is the preferred method to obtain
the best measurement performance.
●
Fixed : Sends the bit pattern defined in the Pattern field. The R&S CMW generates
one fundamental data block to the MS. After a delay to allow for processing, the
MS sends one reverse fundamental data block back to the R&S
CMW. The
R&S CMW can set the bits within a data block to a random pattern or any desired
value (fixed).
