Purpose/Contents

SSD) contains the operating
system and all stored user
data as well as a recovery
partition to restore the PNA
to its as-shipped condition.
Yes This device, located on the
Test Set Motherboard, is
used to store calibration
constants used to make the

that are determined by the
adjustment program can be
stored. There is no other

is in a proprietary format.
