User’s Guide
Disk Options
Surveyor supports saving and examining very large capture files. Two disk options
are available to support large captures,
Cache File Location and Disk Capture
Location. Choose System Settings… from the Configuration menu and select the
Disk Options tab to set either option.
Cache File Location
To support viewing very large captures (greater than 10MB), you can specify the
size and location of a disk cache in the
Cache File Location area. When decoding
large captures, the entire capture typically resides on a remote analyzer device disk,
such as in a THGsE. When using Surveyor to view capture contents, the entire
capture is not downloaded at once to your local disk; only the parts you access are
transferred. However, Surveyor retains the information you have downloaded in a
local disk cache, providing faster retrieval of recently downloaded information. You
specify the location and size of the cache based on the capacity and configuration of
your local system. For example, if your disk drive D: has a capacity of 100GB and
your drive C: has a 4GB capacity loaded with operating systems and applications,
you could set up a 50GB cache directory on disk drive D:.
Use the
Browse button to specify a location for the cache directory and use the slider
to specify its maximum size. Surveyor will not allow you to specify a size greater
than the available free space on your disk drive. The minimum cache size is 40MB.
The cache directory is cleared of files containing information related to a capture
when you close the capture or exit the Surveyor application.
Disk Capture Location
To support local disk captures, you can specify the size limit and location in the
Disk
Capture Location area. Note that this governs the size of large captures created on
your local disk but does not affect the size of captures stored on remote analyzer
devices. This setting affects only large captures made from THGm cards within
your local system. Specify the location of the capture directory based on the
capacity and configuration of your local system.
Use the Browse button to specify a location for the capture directory and use the
slider to specify its maximum size. Surveyor will not allow you to specify a size
greater than the available free space on your disk drive and the minimum size is
40MB. Surveyor uses this directory for all captures made with local cards when
using
Cap+Disk mode. This is not, however, "permanent" storage of the capture
information. Capture information you want to save must be stored in a file using the
Save option. The capture directory is cleared of files containing information related
to this capture when you close Surveyor.
