EX1629 Programming 73
SECTION 6
PROGRAMMING
INTRODUCTION
This section provides programming examples and rationale for use with the EX1629. While this is
not an exhaustive list, it provides a basis for the creation of code for several basic operations.
DEFAULT SETTINGS
The factory default instrument settings after an instrument reset or a power cycle are listed in
Table 6-1. Many programming applications do not require parameter changes from the default
settings and can be made far simpler by the elimination of redundant functions. The EX1629 can
be returned to the reset state at any time through the issuance of the vtex1629_reset function call.
NOTE The EX1629 supports saving user-defined configurations to non-volatile storage. If there is a user-
defined configuration stored in non-volatile storage, that configuration is applied after a reset,
power cycle, or use of the vtex1629_reset function. The vtex1629_clear_stored_config function
can be used to remove a configuration from non-volatile storage, after which the vtex1629_reset
function will restore the instrument to the factory defaults.
