The Channel Voltage Offset Calibration Registers store voltage offset
calibration constants in non-volatile memory. There are 16 registers, one
for each output channel. The register at base + 100
base + 102 stores channel 2, up to base 11E

Voltage Offset Calibration Constant: Writing a 12-bit value to this field
stores a new constant used to calibrate the channel output. Values are in the

memory. Writing to this memory requires a complicated sequence of
register accesses not documented here. It is recommended that calibration
be performed using the SCPI driver for the module, not register access.
Non-volatile memory has finite life, based upon the number of writes. Use
care when writing to this memory.
The contents of this register are loaded into volatile memory at power-on
and not used on an on-going basis.
