Programming Model and Serial Numbers
Since the instrument model and serial numbers are stored only on the A7
Midplane board assembly, this information will be lost when this board
assembly is replaced. Until the instrument model and serial numbers are
restored the instrument application software will not allow any user
measurements to be made, due to the fact that all previously installed license
keys will not be accepted. However, the license files will not be automatically
deleted. Once the model and serial numbers are restored the license files will
then be recognized and accepted, returning the instrument to the capability
that was available prior to the A7 Midplane board assembly replacement.
To program the model and serial numbers into a replacement A7 Midplane
board assembly the N7800A Keysight Calibration Application Software will be
required.
Information regarding N7800A Keysight Calibration Application Software can
be found at:

When the calibration software first detects the instrument it will recognize that
it does not have a valid model and serial number and will prompt the user to
enter the correct values.
Since the instrument model and serial numbers are stored on the A7 Midplane
board assembly, this should only be required when this assembly has been
replaced with a new one.
Be very careful when entering the instrument serial number into the
software, because once it has been written it can no longer be changed.
