set (scope object)

Property Description Writable

MaxWriteFileSize

Provide the maximum size of Filename,

in bytes. This value must be a multiple of

WriteSize.Defaultis536870912.

When the size of a log file reaches

MaxWriteFileSize, the software creates

a subsequently numbered file name, and

continues logging data to that file, up

until the highest log file number you have

specified.Ifthesoftwarecannotcreateany

additional log files, it overwrites the first

log file.

Yes

Grid

Values are 'on' and 'off'.

For scopes of type

'Host' or 'File',this

parameter has no effect.

Yes

Mode

For scopes of type 'Target',indicate

how a scope dis plays the signals. Values

are

'Numerical', 'Redraw' (default),

'Sliding',and'Rolling'.

For scopes of type

File,specifywhenafile

allocation table (FAT) entry is updated.

Values are

'Lazy' or 'Commit'.Both

modes write the signal data to the file.

With

'Commit' mode, each file write

operation simultaneously updates the FAT

entry for the file. This mode is slower, but

the file system always knows the actual

file size. With

'Lazy' mode, the FAT entry

is updated only when the file is closed and

not during each file write operation. This

mode is faster, but if the system crashes

before th e file is clo sed , the fil e system

mightnotknowtheactualfilesize(thefile

contents, howev er, will b e intact).

Yes
