Tektronix 071-0590-00 user manual Wordorder?, Memory allocation for Word Memory storage

Remote Commands

When changing the BUFFER MODE, the stored patterns and the current pattern may be lost. When transitioning from a smaller mode to a larger mode, some of the stored patterns will be lost. When going from larger to smaller, those patterns (including the current pattern) which have lengths greater than the allowed length will be initialized.

Memory allocation for Word Memory storage

1M ………………………….. **

512K WORD0…………………………….

256k WORD0………….WORD1………..WORD2…….

128k WORD0..WORD1..WORD2..WORD3..WORD4..WORD5..

64K 0.. 1.. 2.. 3.. 4.. 5.. 6.. 7.. 8.. 9..

** The 1M storage area is used only for the current WORD pattern.

The chart above can be used to determine which stored patterns will be saved after a MODE transition and in which storage location it will be found. For example, on transitions from 128K to 256K, the stored patterns 0, 2 and 4 of the 128K mode will be found at the 256K locations 0, 1, and 2 respectively, while the stored patterns at 1, 3 and 5 of the 128K will be lost.

On switching to a smaller MODE, only when the pattern in the storage area has a length greater than the new allowed length, will be lost. (Except for 128K to 64K, where WORD5 will always be lost).
