CPU board, not
battery backed.
Turn off
instrument power.
2. Main Memory

User file system
a
, which
includes flatness
calibration, instrument
states, and sweep lists
Firmware
upgrades and
user-saved
data
a
CPU board
(same chip as
firmware
memory, but
managed
separately)
Because this
memory chip
contains 8 MB of
user data
(described here)
and 8 MB of
firmware memory,
a full-chip erase is
not desirable.
User data areas
are selectively and
completely
sanitized by the
procedure “Erase
and Sanitize All
(Option 006 Only)”
